In Ethiopia, particularly in the study area, there is a lack of sufficient data on the prevalence of MRSA and VRSA among healthcare personnel. Therefore, this study was designed to investigate the rate of nasal carriage of methicillin- and vancomycin-resistant Staphylococcus aureus among healthcare workers. Objective This study aimed to assess the nasal carriage rate of methicillin-resistant and vancomycin-resistant staphylococcus aureus , as well as their antibiotic susceptibility pattern among healthcare workers at Jigjiga University Sheik Hassen Yebare Comprehensive Specialized Hospital, Jigjiga, Ethiopia Materials and Methods A hospital-based cross-sectional study was carried out at Jigjiga University Sheik Hassen Yebare Comprehensive Specialized Hospital over a three-month period, from May to July 2024. A total of 178 healthcare professionals working in various wards were enrolled using a convenient sampling method. Nasal swab samples were collected and cultured on Blood Agar and Mannitol Salt Agar, followed by incubation at 37°C for 24 hours. Bacterial identification and antimicrobial susceptibility testing were performed using the automated VITEK 2 Compact system. Result The nasal carriage rate of staphylococcus aureus and methicillin resistance staphylococcus aureus among health care workers was 21.9% (95% CI: 18.3–27.7%) and 71.8% (95%CI: 65.1–75.1%), respectively. Five (17.9%) inducible clindamycin resistance and two (5.1%) vancomycin resistance staphylococcus aureus isolates were also detected. Linezolid, Tigecycline, Vancomycin and Teicoplanin were the most effective antibiotic for both methicillin sensitive and methicillin resistance staphylococcus aureus . The overall prevalence of muti-drug resistance isolates was 41.3% (95% CI: 35.7–46.3%). Conclusions and recommendations: The high rate of methicillin resistance staphylococcus aureus carriage among health care workers is concerning and highlights the need for a further, more comprehensive study. Implementing regular screening of health care personnel is crucial to effectively control and prevent the spread of methicillin resistance staphylococcus aureus MRSA VRSA Nasal carriage Healthcare workers JJUSHYCSH Figures Figure 1 Figure 2 Introduction Staphylococcus aureus(S.aureus ) is a gram positive, non-motile, non-spore former bacteria most healthy people have on their skin and nasal mucosa (1, 2). However it is an important opportunistic human pathogen and frequent cause of both nosocomial and community acquired infections associated with high mortality and morbidity around the world (3). Methicillin-resistant Staphylococcus aureus (MRSA) is a strain of S. aureus that has developed resistance to β-lactam antibiotics such as Methicillin, Oxacillin, Cefoxitin and Nafcillin(4). MRSA develops resistance through the acquisition of the mec A gene, which alters pencillin-binding protein, while VRSA gains resistance via the vanA gene, often acquired from vancomycin-resistance enterococci (VRE) (5). The emergence of MRSA is an important hospital acquired pathogen continues to remain a significant factor for failure of patient management worldwide (6). Methicillin resistant staphylococcus aureus (MRSA) and vancomycin resistant staphylococcus aureus (VRSA) represent significant public health threats due to their ability to cause a wide range of infections, from minor skin and soft tissue infections to severe conditions such as bloodstream infections, pneumonia, and endocarditis that are difficult to treat with standard antibiotics (7, 8). These drug resistant bacteria are associated with increased morbidity, mortality, and healthcare costs, as they require alternative, often more toxic and expensive treatment (9, 10). The problem of MRSA is observed all over the world, although, the burden of infection is high in developing countries including Africa(11). The resistance of MRSA and VRSA to standard antibiotics often necessitates the use of newer or less commonly used antibiotics, such as linezolid, daptomycin or ceftaroline, which may be expensive or have side effects. This growing prevalence of MRSA and VRSA underscores the urgent need for improved infection control measures, more effective antimicrobial stewardship, and the development of novel therapies to combat these formidable pathogens. Health care workers (HCWs) play a significant role in MRSA transmission at health care institutions. Colonized HCWs have been implicated as a source of infection for their patients and themselves as they propagate it to different site of infection through their hands (12). Health care workers who have direct contact between the community and hospital may serve as the agents of the cross-transmission of the community acquired and hospital acquired MRSA (13). Therefore, the colonization of health-care workers with S. aureus , especially MRSA, is considered one of the important risk factors for nosocomial infection (14, 15). Multidrug resistance of nasal S. aureus associated with methicillin-resistant strains is of great public health concern, especially in developing countries (16, 17). Accurate and early determination of methicillin resistance is very important in the prognosis of infections (18). However, there is limited information regarding the prevalence of S. aureus and MRSA nasal colonization among health-care workers. Thus, this study aimed to determine the prevalence and antimicrobial susceptibility patterns of methicillin resistance S. aureus among health-care workers working at Jigjiga University Sheik Hassen Yebare Comprehensive Specialized Hospital, Jigjiga Ethiopia. Materials and Methods Study design, period, and area This hospital-based cross-sectional study was conducted from May 1 to July 30, 2024, at Jigjiga University Sheik Hassen Yebare Comprehensive Specialized Hospital. The hospital is one of the largest tertiary-level referral and teaching hospital in the Somali region, located 630 km from Addis Ababa in eastern Ethiopia. The hospital provides surgical, orthopedic, medical, pediatric, gynecological, obstetric, ENT, neurology, dialysis and intensive care services. It has a separate laboratory units with more than 282 beds and services for people in the surrounding zones and nearby regions(19). Study populations, sample size, and sampling technique The study population consisted of health care workers working at Jigjiga University Sheik Hassan Yebare Comprehensive Specialized Hospital. Participants who had received antibiotics therapy 2weeks prior to the study and individuals who had nasal bleeding were excluded from the study. The minimum sample size was calculated based on the assumption of 5% expected margin of error and 95% confidence interval, taking the prevalence of 12.0% from the previous study that was conducted in Adigrat town (11) using a single population proportion formula and adding a 10% non-response rate, the final sample size was 178 study participants. Health care workers were stratified based on their profession and the sample size was allocated for each stratum by using convenience sampling technique. Data collection and analysis A one-day training session was conducted for the data collector, focusing on data collection procedures and interview techniques. Sociodemographic information of the participants was obtained through face-to-face interviews using semi-structured questionnaires. Sample collection, Transportation and processing Sample collection was performed according to the WHO standard for diagnosis of S. aureus . A sterile cotton swab moistened with normal saline will be passed into the anterior nares of both nostrils of study participants and rotated in both directions to obtain nasal swabs for culture. Each sample was properly labeled with a unique code number, along with the date and time of collection. The samples were then immediately placed in Amies transport medium (Oxoid, England) and transported to the Microbiology Laboratory at Jigjiga University Sheik Hassen Yebare Comprehensive Specialized Hospital (JJUSHYCSH), where they were processed for microbiological analysis within two hours of collection. Isolation of Staphylococcus aureus and Antimicrobial susceptibility test Collected swabs were inoculated onto Mannitol Salt Agar (MSA) (Oxoid Ltd. England) to confirm the fermentation of Mannitol, the growth of golden yellow colonies on MSA surrounded by yellow zones after 24 hours of incubation at 37°C indicated a positive result for S. aureus . These isolates were sub-cultured onto Blood Agar Plate and incubated at 37°C for 24hrs for identification of type of hemolysis. Preliminary gram stain was performed and all gram positive isolates that had beta hemolytic colony on BAP, cluster appearance on the microscope and ferment mannitol (golden yellow colonies) on MSA were identified using an automated Vitek 2 compact system. The VITEK 2 system detects metabolic changes by fluorescence-based techniques which facilitate the identification of most aerobic gram-positive and gram-negative organisms. It uses small plastic cards containing multiple wells filled with either biochemical substrates or antibiotic dilutions(20). The system uses a manual filler sealer to inoculate the cards with the organism. Once these steps are complete, the VITEK 2 seals the cards into a chamber to prevent contamination during processing. The cards are then loaded into the reader incubator, which ejects them at the end of testing. The VITEK 2 uses colorimetric technology with three wavelengths of light to provide broad profiles for the most clinically significant organisms. The analysis is performed by using algorithms to look at a variety of parameters and test conditions to ensure accurate results and early detection of resistance mechanisms through proprietary software. It monitors kinetics of bacterial growth and calculates MICs using a unique algorithm (21). Each bacterial isolate was suspended in 3 milliliters of 0.45% physiological saline solution to the density of 0.5 to 0.60 McFarland measurement using DensiCHEK Plus instrument (Biomerieux, USA).The suspensions were used for both bacterial identification and AST using the Vitek 2 compact system (Biomerieux, USA) according to the manufacturer’s instructions (Biomerieux, USA). All AST inoculum dilutions, card sealing and incubator loading functions were performed by the instrument. Gram positive (GP) cards were used for Gram-positive bacterial identification. The filled and sealed cards were inserted into the Vitek 2 reader-incubation chamber and incubation was performed at temperature 35.5°C. Gram-positive AST cards were used for Gram - positive AST using Vitek-2-compact system. Optical reading of cards was performed every 15 minutes by the Vitek 2 compact system, with a multi-channeled fluorometer and photometer to record fluorescence, turbidity, and colorimetric signals. At the completion of the incubation cycle, bacterial isolates were identified, and MIC values were determined for each antibiotic contained on the card. MDR isolates were tested against different classes of antibiotics representing aminoglycosides, macrolides, cephalosporin, lincosamide, quinolones, tetracycline and sulphonamides. Multiple drug resistance is defined as the resistance of an isolate to at least one agent in three or more antimicrobial classes. Quality control All laboratory activities were conducted in accordance with standard operating procedures (SOPs). To ensure the quality and sterility of culture media, performance testing was conducted for each batch. Specifically, 5% of the prepared media were randomly selected and incubated aerobically at 37°C for 24 hours to assess sterility. The quality and performance of the media were further validated using the reference strain Staphylococcus aureus ATCC 25923. Data quality control Data quality was ensured through the use of pretested questionnaires prior to the main study to verify the feasibility and validity of the study variables. Additionally, data quality was maintained by closely monitoring the completeness of the checklists on-site by the data collectors. The principal investigator, along with the supervisor, actively oversaw the data collection process. Furthermore, the principal investigator regularly and thoroughly reviewed the collected data to ensure its completeness and clarity. Data processing and analysis Data were initially entered into EPI-Info version 7 to perform thorough checks for completeness, accuracy, and consistency. Following this, the cleaned dataset was exported to the Statistical Package for the Social Sciences (SPSS) version 20 for further statistical analysis. Descriptive statistics were computed to summarize the data, including frequencies and proportions for categorical variables, as well as means and standard deviations for continuous variables. The Chi-square test was applied to examine the association between independent variables and outcome measures. Statistical significance was determined at a p-value threshold of less than 0.05. The analyzed results were systematically organized and presented in the form of tables and figures to facilitate clear interpretation and communication. Ethical consideration Ethics clearance was obtained from the Ethics and Review Committee of the College of Medicine and Health Sciences, Jigjiga University, Ethiopia. Before data collection, the study participants were informed of the study, and their written consent for participation was obtained. For child participants, assent/consent to participate was collected from their parents/guardians in a written form, and confidentiality was maintained by omitting their names and personal identifiers throughout the study.

Most of the isolates (56.4%) were identified from nurses and 20.5% of isolates were discovered from pediatric ward. From the total of 39 S. aureus isolates 71.8% (28/39) and 5.1% (2/39) were MRSA and VRSA isolates respectively. Similarly, most of MRSA isolates (71.4%) were from female participants and 57.1% were from age group of 31–40. Like staphylococcus aureus , most of MRSA isolates (60.7%) were identified from Nurses and 25% of them were from pediatric ward. From the 39 isolates of S. aureus 7 (17.9%) were positive for inducible clindamycin resistance (Table 2 ).

However, lowest resistance rate was observed for Tigecycline (2.6%), Linezolid (2.6%) and Vancomycin (5.6%) (Fig. 1 ). Antibiotic resistance patterns of Methicillin resistant Staphylococcus aureus Methicillin resistant Staphylococcus aureus showed the highest resistance to Tetracycline (57.1%), Erythromycin (57.1%), Ciprofloxacin (53.6%) and Trimethoprim/Sulfamethoxazole (46.4%). However, lowest resistance rate was observed for Tigecycline (3.6%), Linezolid (3.6%) and Vancomycin (7.4%) (Fig. 2 ). Multidrug resistance patterns of S.aureus and MRSA Out of 39 S. aureus isolates, 18 of them were sensetive to all antibiotics tested. However 16(41%) of isolates showed multidrug resistance. Additionally, from 28 MRSA isolates 15 (53.6%) of them showed multidrug resistance ( Table 3 ).

Moreover, there is a possibility of transmission of these organisms from patient to patient and healthcare worker to patient (22). Consequently, it is essential to identify MRSA nasal carriage among hospital HCWs, especially those employed in the critical care units. The present study determined the rate of MRSA carriage on HCW at JJUSHYCSH. In this study the prevalence of S. aureus carriage in nares was 21.9% (95% CI: 18.3–27.7%). This observation agrees with previous studies conducted in Bhubaneswar and Ghana (25.5%) (23, 24). However, this was lower than studies conducted in Gaza strip (31%) and Dessie, Ethiopia (28.8%) (25, 26). The local prevalence of MRSA, local infection control strategies and microbiological techniques can account for variations between countries and hospitals. These discrepancies may also be attributed to varying degrees of dedication to infection control practices. In this study, the prevalence of MRSA was 71.8% (95%CI: 65.1–75.1%). This finding was in agreement with study conducted in Minia City, Egypt (65.2%) (27). However, this was higher than studies that reported in a previous study conducted in Bhubaneswar, Iran and Ghana which was 7.5%, 31.3% and 8.5% respectively, (23, 24, 28). The discrepancy in the carriage rate may be due to variation in the study design, sample size and MRSA identification technique. The prevalence of VRSA in this study was 5.1% (95% CI: 2.9–7.3%). However studies conducted at Iran and Pakistan showed that none of study participants was found to be nasal carriers of VRSA (28, 29). However this finding was lower than studies conducted in Gaza strip (15.7%) and Libya (22%) (25, 30). Regarding the antimicrobial resistance pattern, in this study staphylococcus aureus shows the highest resistance to Tetracycline (48.7%), Trimethoprim/Sulfamethoxazole (43.6%), Erythromycin (43.6%), Ciprofloxacin (35.9%) and Cindamycine (30.8%). This was similar with studies done in Oman (Tetracycline (50%), Trimethoprim/Sulfamethoxazole (43%), Erythromycin (48%), Cindamycine (30.8%) (31). However, highest sensetivity was oserved in Tigecycline (97.4%), Linezolid (97.4%), Vancomycin (94.7%), and Teicopanin (92.3%). This was in agrrement with studies conducted in Oman (31) and North India (100% sensrtivity for each) (20). Also studies conduted in Somalia showed 100% sensetivity rate for Linezolid and Vancomycin (32). This could be due to the limited prescription and use of these antibiotics in the community. Like methicillin sensitive staphylococcus aureus MRSA isolates showed highest resistance to similar antibiotics except variying in percent which showed Tetracycline (57.1%), Erythromycin (57.1%), Ciprofloxacin (53.6%), Trimethoprim/Sulfamethoxazole (46.4%) and Cindamycine (39.3%) resistance rate. However, highest sensetivity was observed in Tigecycline (96.4%), Linezolid (96.4%), Vancomycin (92.6%) and Teicoplanin (89.3%) like methicillin sensitive staphylococcus aureus. In the present study, the overall proportion of MDR among Staphylococcus aureus was 41.3% (95% CI: 35.7–46.3%). Of these, 93.7% was observed on MRSA isolates. This finding is comparable with reports from Sudan which shows 95.7% MDR in MRSA isolates (33). Conclusion and recommendation The result of this study showed that 71.8% of health care workers were an MRSA carrier which is very high prevalence. The alarmingly high prevalence of MRSA carriage rate in our study area should be addressed in a larger study in the future. Consequently, infection prevention and control measures in hospitals should receive special attention and should be given to infection prevention and control strategies in the hospital, and routine screening of apparently asymptomatic Healthcare personnel is essential to preventing the spread of infection.

Jigjiga University Sheik Hassen Yebare Comprehensive Specialized Hospital, Jigjiga, Ethiopia","fulltext":[{"header":"Introduction","content":"\u003cp\u003e\u003cem\u003eStaphylococcus aureus(S.aureus\u003c/em\u003e) is a gram positive, non-motile, non-spore former bacteria most healthy people have on their skin and nasal mucosa (1, 2). However it is an important opportunistic human pathogen and frequent cause of both nosocomial and community acquired infections associated with high mortality and morbidity around the world (3).\u003c/p\u003e\u003cp\u003eMethicillin-resistant \u003cem\u003eStaphylococcus aureus\u003c/em\u003e(MRSA) is a strain of \u003cem\u003eS. aureus\u003c/em\u003e that has developed resistance to β-lactam antibiotics such as Methicillin, Oxacillin, Cefoxitin and Nafcillin(4). MRSA develops resistance through the acquisition of the \u003cem\u003emec\u003c/em\u003eA gene, which alters pencillin-binding protein, while VRSA gains resistance via the vanA gene, often acquired from vancomycin-resistance enterococci (VRE) (5). The emergence of MRSA is an important hospital acquired pathogen continues to remain a significant factor for failure of patient management worldwide (6).\u003c/p\u003e\u003cp\u003eMethicillin \u003cem\u003eresistant staphylococcus aureus\u003c/em\u003e (MRSA) and vancomycin resistant \u003cem\u003estaphylococcus aureus\u003c/em\u003e (VRSA) represent significant public health threats due to their ability to cause a wide range of infections, from minor skin and soft tissue infections to severe conditions such as bloodstream infections, pneumonia, and endocarditis that are difficult to treat with standard antibiotics (7, 8). These drug resistant bacteria are associated with increased morbidity, mortality, and healthcare costs, as they require alternative, often more toxic and expensive treatment (9, 10).\u003c/p\u003e\u003cp\u003eThe problem of MRSA is observed all over the world, although, the burden of infection is high in developing countries including Africa(11). The resistance of MRSA and VRSA to standard antibiotics often necessitates the use of newer or less commonly used antibiotics, such as linezolid, daptomycin or ceftaroline, which may be expensive or have side effects. This growing prevalence of MRSA and VRSA underscores the urgent need for improved infection control measures, more effective antimicrobial stewardship, and the development of novel therapies to combat these formidable pathogens.\u003c/p\u003e\u003cp\u003eHealth care workers (HCWs) play a significant role in MRSA transmission at health care institutions. Colonized HCWs have been implicated as a source of infection for their patients and themselves as they propagate it to different site of infection through their hands (12). Health care workers who have direct contact between the community and hospital may serve as the agents of the cross-transmission of the community acquired and hospital acquired MRSA (13).\u003c/p\u003e\u003cp\u003eTherefore, the colonization of health-care workers with \u003cem\u003eS. aureus\u003c/em\u003e, especially MRSA, is considered one of the important risk factors for nosocomial infection (14, 15). Multidrug resistance of nasal \u003cem\u003eS. aureus\u003c/em\u003e associated with methicillin-resistant strains is of great public health concern, especially in developing countries (16, 17). Accurate and early determination of methicillin resistance is very important in the prognosis of infections (18).\u003c/p\u003e\u003cp\u003eHowever, there is limited information regarding the prevalence of \u003cem\u003eS. aureus\u003c/em\u003e and MRSA nasal colonization among health-care workers. Thus, this study aimed to determine the prevalence and antimicrobial susceptibility patterns of methicillin resistance \u003cem\u003eS. aureus\u003c/em\u003e among health-care workers working at Jigjiga University Sheik Hassen Yebare Comprehensive Specialized Hospital, Jigjiga Ethiopia.\u003c/p\u003e"},{"header":"Materials and Methods","content":"\u003cdiv id=\"Sec3\" class=\"Section2\"\u003e\u003ch2\u003eStudy design, period, and area\u003c/h2\u003e\u003cp\u003eThis hospital-based cross-sectional study was conducted from May 1 to July 30, 2024, at Jigjiga University Sheik Hassen Yebare Comprehensive Specialized Hospital. The hospital is one of the largest tertiary-level referral and teaching hospital in the Somali region, located 630 km from Addis Ababa in eastern Ethiopia. The hospital provides surgical, orthopedic, medical, pediatric, gynecological, obstetric, ENT, neurology, dialysis and intensive care services. It has a separate laboratory units with more than 282 beds and services for people in the surrounding zones and nearby regions(19).\u003c/p\u003e\u003c/div\u003e\n\u003ch3\u003eStudy populations, sample size, and sampling technique\u003c/h3\u003e\n\u003cp\u003eThe study population consisted of health care workers working at Jigjiga University Sheik Hassan Yebare Comprehensive Specialized Hospital. Participants who had received antibiotics therapy 2weeks prior to the study and individuals who had nasal bleeding were excluded from the study. The minimum sample size was calculated based on the assumption of 5% expected margin of error and 95% confidence interval, taking the prevalence of 12.0% from the previous study that was conducted in Adigrat town (11) using a single population proportion formula and adding a 10% non-response rate, the final sample size was 178 study participants.

A sterile cotton swab moistened with normal saline will be passed into the anterior nares of both nostrils of study participants and rotated in both directions to obtain nasal swabs for culture. Each sample was properly labeled with a unique code number, along with the date and time of collection. The samples were then immediately placed in Amies transport medium (Oxoid, England) and transported to the Microbiology Laboratory at Jigjiga University Sheik Hassen Yebare Comprehensive Specialized Hospital (JJUSHYCSH), where they were processed for microbiological analysis within two hours of collection.\u003c/p\u003e\n\u003ch3\u003eIsolation of Staphylococcus aureus and Antimicrobial susceptibility test\u003c/h3\u003e\n\u003cp\u003e\u003c/p\u003e\u003cdiv class=\"BlockQuote\"\u003e\u003cp\u003eCollected swabs were inoculated onto Mannitol Salt Agar (MSA) (Oxoid Ltd.

These isolates were sub-cultured onto Blood Agar Plate and incubated at 37°C for 24hrs for identification of type of hemolysis. Preliminary gram stain was performed and all gram positive isolates that had beta hemolytic colony on BAP, cluster appearance on the microscope and ferment mannitol (golden yellow colonies) on MSA were identified using an automated Vitek 2 compact system.\u003c/p\u003e\u003cp\u003eThe VITEK 2 system detects metabolic changes by fluorescence-based techniques which facilitate the identification of most aerobic gram-positive and gram-negative organisms. It uses small plastic cards containing multiple wells filled with either biochemical substrates or antibiotic dilutions(20). The system uses a manual filler sealer to inoculate the cards with the organism. Once these steps are complete, the VITEK 2 seals the cards into a chamber to prevent contamination during processing. The cards are then loaded into the reader incubator, which ejects them at the end of testing. The VITEK 2 uses colorimetric technology with three wavelengths of light to provide broad profiles for the most clinically significant organisms. The analysis is performed by using algorithms to look at a variety of parameters and test conditions to ensure accurate results and early detection of resistance mechanisms through proprietary software. It monitors kinetics of bacterial growth and calculates MICs using a unique algorithm (21).\u003c/p\u003e\u003cp\u003eEach bacterial isolate was suspended in 3 milliliters of 0.45% physiological saline solution to the density of 0.5 to 0.60 McFarland measurement using DensiCHEK Plus instrument (Biomerieux, USA).The suspensions were used for both bacterial identification and AST using the Vitek 2 compact system (Biomerieux, USA) according to the manufacturer’s instructions (Biomerieux, USA). All AST inoculum dilutions, card sealing and incubator loading functions were performed by the instrument.\u003c/p\u003e\u003cp\u003eGram positive (GP) cards were used for Gram-positive bacterial identification. The filled and sealed cards were inserted into the Vitek 2 reader-incubation chamber and incubation was performed at temperature 35.5°C. Gram-positive AST cards were used for Gram - positive AST using Vitek-2-compact system. Optical reading of cards was performed every 15 minutes by the Vitek 2 compact system, with a multi-channeled fluorometer and photometer to record fluorescence, turbidity, and colorimetric signals.\u003c/p\u003e\u003cp\u003eAt the completion of the incubation cycle, bacterial isolates were identified, and MIC values were determined for each antibiotic contained on the card. MDR isolates were tested against different classes of antibiotics representing aminoglycosides, macrolides, cephalosporin, lincosamide, quinolones, tetracycline and sulphonamides. Multiple drug resistance is defined as the resistance of an isolate to at least one agent in three or more antimicrobial classes.\u003c/p\u003e\u003c/div\u003e\u003cp\u003e\u003c/p\u003e\u003cdiv id=\"Sec8\" class=\"Section2\"\u003e\u003ch2\u003eQuality control\u003c/h2\u003e\u003cp\u003eAll laboratory activities were conducted in accordance with standard operating procedures (SOPs). To ensure the quality and sterility of culture media, performance testing was conducted for each batch. Specifically, 5% of the prepared media were randomly selected and incubated aerobically at 37°C for 24 hours to assess sterility. The quality and performance of the media were further validated using the reference strain \u003cem\u003eStaphylococcus aureus\u003c/em\u003e ATCC 25923.\u003c/p\u003e\u003c/div\u003e\n\u003ch3\u003eData quality control\u003c/h3\u003e\n\u003cp\u003eData quality was ensured through the use of pretested questionnaires prior to the main study to verify the feasibility and validity of the study variables. Additionally, data quality was maintained by closely monitoring the completeness of the checklists on-site by the data collectors. The principal investigator, along with the supervisor, actively oversaw the data collection process. Furthermore, the principal investigator regularly and thoroughly reviewed the collected data to ensure its completeness and clarity.\u003c/p\u003e\n\u003ch3\u003eData processing and analysis\u003c/h3\u003e\n\u003cp\u003eData were initially entered into EPI-Info version 7 to perform thorough checks for completeness, accuracy, and consistency. Following this, the cleaned dataset was exported to the Statistical Package for the Social Sciences (SPSS) version 20 for further statistical analysis. Descriptive statistics were computed to summarize the data, including frequencies and proportions for categorical variables, as well as means and standard deviations for continuous variables. The Chi-square test was applied to examine the association between independent variables and outcome measures. Statistical significance was determined at a p-value threshold of less than 0.05. The analyzed results were systematically organized and presented in the form of tables and figures to facilitate clear interpretation and communication.\u003c/p\u003e\u003cdiv id=\"Sec11\" class=\"Section2\"\u003e\u003ch2\u003eEthical consideration\u003c/h2\u003e\u003cp\u003e Ethics clearance was obtained from the Ethics and Review Committee of the College of Medicine and Health Sciences, Jigjiga University, Ethiopia.

potential sources of MRSA organisms due to the close contact of patients with healthcare workers, patient care equipment and hospital environment. Moreover, there is a possibility of transmission of these organisms from patient to patient and healthcare worker to patient (22). Consequently, it is essential to identify MRSA nasal carriage among hospital HCWs, especially those employed in the critical care units. The present study determined the rate of MRSA carriage on HCW at JJUSHYCSH.\u003c/p\u003e\u003cp\u003eIn this study the prevalence of \u003cem\u003eS. aureus\u003c/em\u003e carriage in nares was 21.9% (95% CI: 18.3–27.7%). This observation agrees with previous studies conducted in Bhubaneswar and Ghana (25.5%) (23, 24). However, this was lower than studies conducted in Gaza strip (31%) and Dessie, Ethiopia (28.8%) (25, 26). The local prevalence of MRSA, local infection control strategies and microbiological techniques can account for variations between countries and hospitals. These discrepancies may also be attributed to varying degrees of dedication to infection control practices.\u003c/p\u003e\u003cp\u003eIn this study, the prevalence of MRSA was 71.8% (95%CI: 65.1–75.1%). This finding was in agreement with study conducted in Minia City, Egypt (65.2%) (27). However, this was higher than studies that reported in a previous study conducted in Bhubaneswar, Iran and Ghana which was 7.5%, 31.3% and 8.5% respectively, (23, 24, 28). The discrepancy in the carriage rate may be due to variation in the study design, sample size and MRSA identification technique.\u003c/p\u003e\u003cp\u003eThe prevalence of VRSA in this study was 5.1% (95% CI: 2.9–7.3%). However studies conducted at Iran and Pakistan showed that none of study participants was found to be nasal carriers of VRSA (28, 29). However this finding was lower than studies conducted in Gaza strip (15.7%) and Libya (22%) (25, 30).\u003c/p\u003e\u003cp\u003eRegarding the antimicrobial resistance pattern, in this study \u003cem\u003estaphylococcus aureus\u003c/em\u003e shows the highest resistance to Tetracycline (48.7%), Trimethoprim/Sulfamethoxazole (43.6%), Erythromycin (43.6%), Ciprofloxacin (35.9%) and Cindamycine (30.8%). This was similar with studies done in Oman (Tetracycline (50%), Trimethoprim/Sulfamethoxazole (43%), Erythromycin (48%), Cindamycine (30.8%) (31). However, highest sensetivity was oserved in Tigecycline (97.4%), Linezolid (97.4%), Vancomycin (94.7%), and Teicopanin (92.3%). This was in agrrement with studies conducted in Oman (31) and North India (100% sensrtivity for each) (20). Also studies conduted in Somalia showed 100% sensetivity rate for Linezolid and Vancomycin (32). This could be due to the limited prescription and use of these antibiotics in the community.\u003c/p\u003e\u003cp\u003eLike methicillin sensitive \u003cem\u003estaphylococcus aureus\u003c/em\u003e MRSA isolates showed highest resistance to similar antibiotics except variying in percent which showed Tetracycline (57.1%), Erythromycin (57.1%), Ciprofloxacin (53.6%), Trimethoprim/Sulfamethoxazole (46.4%) and Cindamycine (39.3%) resistance rate. However, highest sensetivity was observed in Tigecycline (96.4%), Linezolid (96.4%), Vancomycin (92.6%) and Teicoplanin (89.3%) like methicillin sensitive \u003cem\u003estaphylococcus aureus.\u003c/em\u003e\u003c/p\u003e\u003cp\u003eIn the present study, the overall proportion of MDR among \u003cem\u003eStaphylococcus aureus\u003c/em\u003e was 41.3% (95% CI: 35.7–46.3%). Of these, 93.7% was observed on MRSA isolates. This finding is comparable with reports from Sudan which shows 95.7% MDR in MRSA isolates (33).\u003c/p\u003e"},{"header":"Conclusion and recommendation","content":"\u003cp\u003eThe result of this study showed that 71.8% of health care workers were an MRSA carrier which is very high prevalence. The alarmingly high prevalence of MRSA carriage rate in our study area should be addressed in a larger study in the future. Consequently, infection prevention and control measures in hospitals should receive special attention and should be given to infection prevention and control strategies in the hospital, and routine screening of apparently asymptomatic Healthcare personnel is essential to preventing the spread of infection.\u003c/p\u003e"},{"header":"Abbreviations","content":"\u003cp\u003eAMR, antimicrobial resistance; ATCC, American Type Culture Collection; CLSI, Clinical and Laboratory Standard Institute; HCWs: Heath care workers; JJUSHYCSH: \u0026nbsp;Jigjiga University Sheik Hassen Yebare Comprehensive Specialized Hospital;\u0026nbsp;MDR: Multidrug resistance; MRSA: Methicillin resistance \u003cem\u003estaphylococcus aureus\u003c/em\u003e; MSSA: Methicillin sensitive \u003cem\u003estaphylococcus aureus\u003c/em\u003e; SPSS, Statistical Package for Social Sciences; VRSA: Vancomycin resistance \u003cem\u003estaphylococcus aureus\u003c/em\u003e\u003c/p\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003e\u003cem\u003eAcknowledgement\u0026nbsp;\u003c/em\u003e\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eFirst, our heartfelt gratitude goes to Jigjiga University for funding this research.

In Ethiopia, particularly in the study area, there is a lack of sufficient data on the prevalence of MRSA and VRSA among healthcare personnel. Therefore, this study was designed to investigate the rate of nasal carriage of methicillin- and vancomycin-resistant \u003cem\u003eStaphylococcus aureus\u003c/em\u003e among healthcare workers.\u003c/p\u003e\u003ch2\u003eObjective\u003c/h2\u003e\u003cp\u003eThis study aimed to assess the nasal carriage rate of methicillin-resistant and vancomycin-resistant \u003cem\u003estaphylococcus aureus\u003c/em\u003e, as well as their antibiotic susceptibility pattern among healthcare workers at Jigjiga University Sheik Hassen Yebare Comprehensive Specialized Hospital, Jigjiga, Ethiopia\u003c/p\u003e\u003ch2\u003eMaterials and Methods\u003c/h2\u003e\u003cp\u003eA hospital-based cross-sectional study was carried out at Jigjiga University Sheik Hassen Yebare Comprehensive Specialized Hospital over a three-month period, from May to July 2024. A total of 178 healthcare professionals working in various wards were enrolled using a convenient sampling method. Nasal swab samples were collected and cultured on Blood Agar and Mannitol Salt Agar, followed by incubation at 37\u0026deg;C for 24 hours. Bacterial identification and antimicrobial susceptibility testing were performed using the automated VITEK 2 Compact system.\u003c/p\u003e\u003ch2\u003eResult\u003c/h2\u003e\u003cp\u003eThe nasal carriage rate of \u003cem\u003estaphylococcus aureus\u003c/em\u003e and methicillin resistance \u003cem\u003estaphylococcus aureus\u003c/em\u003e among health care workers was 21.9% (95% CI: 18.3\u0026ndash;27.7%) and 71.8% (95%CI: 65.1\u0026ndash;75.1%), respectively. Five (17.9%) inducible clindamycin resistance and two (5.1%) vancomycin resistance \u003cem\u003estaphylococcus aureus\u003c/em\u003e isolates were also detected. Linezolid, Tigecycline, Vancomycin and Teicoplanin were the most effective antibiotic for both methicillin sensitive and methicillin resistance \u003cem\u003estaphylococcus aureus\u003c/em\u003e.
