The draft genome of an extended-spectrum β-Lactamase-producing Klebsiella pneumoniae subsp. pneumoniae strain Cow102, isolated from cow milk used for production of traditional foods in Nigeria, is reported. Result The genome has a total length of 5,359,907 bp with 70 contigs and GC content of 57.35%. A total of 5,244 protein coding sequences were detected with 31% mapped to a subsystem, and genes coding for amino acids and derivatives being the most prevalent. Multilocus sequence typing revealed that the strain had new allelic profile assigned to the novel 6914 sequence type possessing capsular and lipopolysaccharide antigen K locus 122 with an unknown K type (KL122) and O locus O1/O2v2 with type O2afg, respectively. A total of 28 resistance-related genes, 98 virulence-related genes, two plasmids and five phages were identified in the genome. Comparative analysis indicated translocation was the most common structural rearrangements in the genome. Conclusion Whole-genome sequencing and bioinformatics analysis revealed new allelic profile, structural rearrangements, virulence and drug resistance factors in the genome, however, further studies are required to characterize the capsular K type oof Cow102. animal milk draft genome Klebsiella pneumoniae subsp. pneumoniae multidrug resistance Figures Figure 1 Figure 2 Background In recent years, there has been growing concern about the emergence and spread of antibiotic resistance in bacteria [ 1 ]. One of such examples involve the rising incidence of various species, especially strains of Klebsiella pneumoniae , acquiring the capability to synthesize extended-spectrum β-Lactamase (ESBL) enzymes that confer resistance to a broad range of β-lactam antibiotics [ 2 ]. Members of the Klebsiella genus, a Gram-negative non-motile, encapsulated, facultative anaerobic bacterium, within the family Enterobacteriaceae cause a wide range of infections in both humans and animals. Klebsiella pneumoniae is a versatile bacterium that can be found in various environments, including the oral cavity, skin, and gastrointestinal tracts of different mammals [ 3 ]. While normally present as a part of the human microbiota, this bacterium can also act as an opportunistic pathogen, leading to a range of infections such as pneumonia, septicaemia, urinary tract infections, and soft tissue infections, among others [ 3 ]. Beta-lactam antibiotics, e.g., penicillins, cephalosporins, monobactams, and carbapenems, which are widely used as therapeutic agents to combat bacterial infections, exert their antimicrobial effects by cleaving to the penicillin-binding protein [ 2 ]. This binding prevents the biosynthesis of the bacterial cell membrane, ultimately inhibiting the growth and survival of the bacteria [ 2 ]. However, the presence of ESBLs considerably reduces the efficacy of beta-lactam antibiotics, creating a serious problem in the treatment of infection by ESBL-producing bacteria. In recent years, the World Health Organization (WHO) has recognized K. pneumoniae as being among the top priority pathogens due to the significant morbidity and mortality rates associated with its infections and status as a major worldwide reservoir and vector for antibiotic resistance [ 1 , 4 ]. As a result, there is a growing demand for genotyping this important pathogen to better understand its genetic characteristics and transmission patterns. One of the molecular methods commonly employed for this purpose is multilocus sequence typing (MLST) based on housekeeping genes, this allows for the characterization of the genetic relationship between different bacterial strains. Klebsiella strains are largely oligoclonal [ 5 ], which means they can be assigned into several unique sequence types (STs). This method of classification provides unambiguous and reliable data, which allows researchers and healthcare professionals gain valuable insights into the genetic diversity and transmission patterns of this pathogen. In Nigeria, a significant proportion of the available data that employed molecular techniques to identify Klebsiella strain is predominantly derived from studies conducted in healthcare facilities and medical settings [ 6 , 7 ]. Studying the genomic characteristics of ESBL-producing K. pneumoniae isolated from alternative sources, such as animal milk, could offer fresh perspectives on the transmission of these opportunistic pathogens across different niches in Nigeria. Moreover, genome typing of Klebsiella strains from various sources will provide resources for bio-surveillance. This research also contributes to understanding antibiotic resistance dissemination as well as the development of targeted interventions and preventive measures to mitigate the spread of K. pneumoniae in both animal and human populations. Results and discussion Antimicrobial susceptibility profile Klebsiella species are major global reservoirs and conduit of drug resistance genes between various bacterial niches [ 8 ]. We report the draft genome sequence of an ESBL-producing K. pneumoniae subsp. pneumoniae strain Cow102 previously isolated from cow milk [ 9 , 10 ]. The phenotypic antimicrobial susceptibility profile of strain cow102 showed resistance to cephalosporins, carbapenem, and drugs from different classes of antibiotics including aminoglycosides (streptomycin), quinolone (ciprofloxacin, nalidixic acid), beta-lactams (amoxicillin + clavulanic acid, ampicillin, cefotaxime, ceftazidime, piperacillin), folic acid synthesis inhibitor (trimethoprim/sulfamethoxazole), monobactams (aztreonam), fosfomycin, and tetracycline. The strain was identified as an ESBL producer due to its resistance to aztreonam, cefotaxime, ceftazidime, and ceftriaxone, which are commonly used as indicators for ESBL production. Haemolysis test The strain reported in this study was non-hemolytic on blood agar and lacked the genes hlyA and cnf-1 that code for this function. General genome features Illumina sequencing of the genomic DNA of strain cow102 generated 12,005,232 total read pairs (2 × 150 bp) giving approximately 336 × coverage. The assembly genome totalled 5,359,907 bp with 70 contigs, an N50 value of 376,296 bp, and a GC content of 57.35%. The assembly was characterized using CheckM as 100% complete with, 0.1% contamination, 99.4% and 97.8% coarse and fine consistencies, respectively. Genome annotation performed using RASTk identified, a total of 5,244 protein coding sequences (CDS), 72 transfer RNA (tRNA) genes, and 5 ribosomal RNA (rRNA) genes. There were 4,605 proteins with functional assignments and 639 hypothetical proteins in the annotation. Among the proteins with functional assignments, 1,457 possessed Enzyme Commission (EC) numbers, 1,208 had Gene Ontology (GO) assignments, and 1,065 contained KEGG pathway mappings. Also, about 31% of the CDS was mapped to a subsystem. Genes responsible for amino acids and derivatives (417 ORFs), protein metabolism (227 ORFs), and cofactors, vitamins, prosthetic groups, and pigments (196 ORFs) were abundant among the SEED subsystem categories. An overview of the subsystem categories and feature counts is shown in Fig. 1A while the genome annotation can be viewed on Figshare. Phylogenetic analysis, Multilocus Sequence typing (MLST) and capsular typing The whole-genome phylogenetic analysis showed that strain Cow102 is closely related to K. pneumoniae subsp. pneumoniae strains IS39, DSM30104, ISC21, and DSM30104, all of which belong to the HS11286 group (Fig. 1B). Multilocus Sequence typing analysis revealed that the current isolate had a new allelic profile [(gapA (2), infB (3), mdh (70) pgi (1) phoE (275), rpoB (44) and tonB (39)], assigned as sequence type 6914 based on the standard 7-gene MLST scheme, initially defined by Diancourt et al [ 11 ]. eBURST analyses showed that ST6914 clustered closely with ST494, ST4138, ST4139 and ST6476 (Figure S1 A). The current strain, ST6914 is a triple-locus variant to all closely clustered ST, differing at the phoE, rpoB and tonB loci. The serotyping of ST6914 revealed a 99.96% match with K locus 122 with an unknown K type (KL122) for the capsular (K typing) antigen (Figure S1 B) using the wzi sequencing K-typing method [ 12 ], and a 98.51% match with O locus O1/O2v2 with type O2afg for the lipopolysaccharide (O typing) antigen (Figure S1 C). Antimicrobial resistance genes Several studies in Nigeria reported drug-resistant Klebsiella strains in raw animal milk and milk products; however, genomic data and serotypes of the reported strains are rare [ 13 , 14 ]. Molecular characterization of the resistance factors associated with strain Cow102 revealed the presence of 38 Antibiotic Resistance Genes (ARGs) (Table 1 and Fig. 2), out of which 24 genes were fully concordant with the phenotypically derived resistance profile. The resistance genes identified in strain Cow102 include core chromosomal resistance genes belonging to the bla SHV family, which transfer resistance to beta-lactam antibiotics. In addition, acquired genes such as aadA2, an aminoglycoside nucleotidyltransferase gene; catA2 and catII, which confer resistance by enzymatic inactivation of amphenicol antibiotics; TEM families, which transfer resistance through similar mechanisms as bla SHV family; and Escherichia coli FosA and oqxAB gene conferring resistance to fosfomycin and quinolones, respectively, were found. Furthermore, the presence of the efflux pump gene, Tet (D), which provides resistance to tetracycline, was expected (Table 1 and Fig. 2). This is likely due to the common practice among veterinary and para-veterinary professionals in Nigeria to prescribe oxytetracycline for treating diseases [ 15 , 16 ]. Table 1 Antimicrobial resistance genes identified in Klebsiella pneumoniae subsp. pneumoniae strain Cow102 and conferring resistance to tested antibiotics Resistance gene Antibiotic Class Antibiotic (phenotype observed) aadA2b aminoglycoside Streptomycin (resistant) blaSHV-1 a beta-lactam Amoxicillin (resistant) a,b,c,d,f,g,n blaSHV-11 b Amoxicillin + clavulanic acid (resistant) d blaSHV-13 c Ampicillin(resistant) a,b,c,d,f,g,n blaSHV-26 d Ampicillin + clavulanic acid (resistant) d blaSHV-70 e Aztreonam (resistant) c,e,g blaSHV-78 f Cefotaxime (resistant) c,e,g blaSHV-98 g Ceftazidime (resistant) c,e,g blaSHV-145 h Ceftriaxone (resistant) c,e,g blaSHV-161 i Piperacillin (resistant) a,b,c,d,f,g,n blaSHV-179 j blaSHV-185 k blaSHV-194 l blaSHV-199 m blaTEM-1B n catA2 amphenicol Chloramphenicol (intermediate) dfrA16 q folic acid synthesis inhibitor trimethoprim o,q /sulfamethoxazole p (resistant) fosA fosfomycin Fosfomycin (intermediate) fosA5 fosA6 OqxA o Quinolone and folic acid synthesis inhibitor Ciprofloxacin (intermediate) OqxB o Nalidixic acid (resistant) sul1 p folic acid synthesis inhibitor Sul2 p Tet(D) tetracycline Tetracyclin (resistant) Key: Superscripts represent combination of resistance gene conferring resistance to an antibiotic The genome as shown in Fig. 2 includes several additional genes associated with antimicrobial resistance that were not phenotypically tested, and their presence alone does not confirm resistance. These include KatG gene and operons MarA, MarB, and MarR, which are involved in enzymatic catalysis of antibiotics. The BcrC gene serves as a protective protein for antibiotic targets. GdpD and PgsA genes are involved in altering the charge of the cell wall, while OccD6/OprQ and OprB modulate antibiotic permeability. The presence of AcrAB-TolC, EmrAB-TolC, H-NS, and OxyR suggests the role of regulatory factors in modulating the expression of antibiotic resistance genes. Additionally, the genome harbours other ARGs that were acquired through horizontal gene transfer such as the E. coli UhpT gene, which carries a mutation conferring resistance to fosfomycin, mdfA gene, an efflux pump, and multidrug transporter, as well as the Haemophilus influenzae PBP3 gene which confers resistance to beta-lactam antibiotics (Fig. 2). Comprehensive details of ARGs, their orientation and genomic location is presented in Table S1 . Virulence factors Profiling of virulence features in the current strain revealed the presence of 98 virulence factors (Table 2 ) classified into 12 categories: adherence (15 genes), antimicrobial activity/competitive advantage (3 genes), biofilm formation (10 genes), effector delivery system (25 genes), exotoxins (2 genes), immune modulation (16 genes), invasion (2 genes), motility (3 genes), nutritional/metabolic factors (14 genes), regulation (7 genes), and other (1 gene).

eight IS families: IS1, IS3, IS5, IS110, IS66, IS91, IS630, and ISNCY in the genome of strain Cow102. A comprehensive list of all identified IS, along with their corresponding CDS positions and terminal inverted repeats (TIR) is presented in Table S2 . The only plasmids found in the present genome were IncFIB(K)-1-Kpn3 and Col440I_1. These plasmids were respectively detected in 16 (67%) and 11 (46%) of 24 K. pneumoniae isolates from powdered milk from Germany [ 17 ]. Additionally, five bacteriophages were detected, of which three (Klebsi phiKO2, Escher 500465, Entero cdtI) were intact, one (Salmon 118970 sal3) was incomplete, and one (Escher RCS47) yielded inconclusive results. Figure S1 illustrates the positions of these bacteriophages within the CDS region of the Cow102 strain. Comparative genomics A first glance at the genomic comparison analysis between the current and 22 other strains of K. pneumoniae suggested a high level of sequence similarity with pairwise average nucleotide identity (ANI) ranging from 99.1–99.9% (Figure S3 ). It is worthy of note that the other strains were from various hosts (chicken, cow, human, pig) and sources (chicken faeces, open wound, blood, urine, vaginal swab, pork, cow milk). Pairwise whole-genome alignments with CLC genomic workbench for all 22 assemblies against the cow102 strain revealed sequence alignment percentages of about 85% and 90% (Figure S3 ), despite the fact that huge differences were observed in assembly metrics such as N50 and GC content. A closer look at the variations between the genomes using DNAdiff found significant differences ( p < 0.05) in sequence inversions, insertions/deletions (indels), relocations and translocations between the assemblies and the examined strains (Table S3 ). The most common structural rearrangements discovered were translocations (x̄=105), which occurred between neighbouring 1-to-1 alignment blocks in different sequences. Additionally, there was an average of approximately nine breaks in the alignment where adjacent 1-to-1 alignment blocks were in the same sequence (relocations), and two somewhat unusual breaks where adjacent 1-to-1 alignment blocks were inverted with regard to each other (inversions). Furthermore, an average of 221 insertion events, three tandem duplication insertion events (TandemIns), 32995 Single Nucleotide Polymorphism (SNPs) and 2629 Single Nucleotide Materials and methods Bacterial isolation and growth conditions The current report stemmed from a 2019 study that sought to identify functional bacteria in animal milk [ 9 , 10 ]. A synopsis of the sample collection and bacterial isolation conducted is provided here. Cow milk samples (n = 20) were collected from dairy farms in Sokoto State, Nigeria, between May and June 2019. Each sample was subjected to six dilution series. Bacteria were isolated on De-Mann Rogosa Sharpe (MRS) agar plates supplemented with D-Sorbitol and incubation of inoculated plates was performed in anaerobic conditions at 37°C for 24 hours. Antimicrobial susceptibility testing and screening of the ESBL production Antimicrobial susceptibility testing (AST) was done using the agar diffusion method and the Clinical and Laboratory Standards Institute (CLSI) M100 guideline (31st edition) for drug selection and interpretation of result. Briefly, Mueller–Hinton agar plates (20ml) were overlaid with MacFarland standardized broth containing the Klebsiella pneumoniae subsp. pneumoniae strain Cow102. The plates were then treated with a selection of antibiotics from various classes: aminoglycosides (streptomycin [10 µg]) quinolones (ciprofloxacin [5 µg], nalidixic acid [30 µg]) beta-lactams (amoxicillin + clavulanic acid [20/10 µg], ampicillin [10 µg], cefotaxime [30 µg], ceftazidime [30 µg], piperacillin [100 µg]), folic acid synthesis inhibitor (trimethoprim/sulfamethoxazole [1.25/23.75 µg]), monobactams (aztreonam [30 µg]) and other antibiotics (fosfomycin [200 µg], tetracycline [30 µg]). Plates were incubated at 37°C for 24 hours under aerobic conditions, thereafter the diameters of the inhibition zones were measured. The strain was considered susceptible or resistant, using the breakpoints established by CLSI. ESBL-production was suspected due to reduced susceptibility to Ceftazidime (30 µg) and Cefotaxime (30 µg) in the AST. The Combination Disc Test (CDT), as recommended by the CLSI, was employed to confirm the production of ESBL. In summary, clavulanic acid (10 µg) was combined with each of cefotaxime (30 µg) and ceftazidime (30 µg). The test was considered positive when an increase in the growth-inhibitory zone around either the ceftazidime or the cefotaxime disk with clavulanic acid was ≥ 5 mm the diameter around the disk containing ceftazidime or cefotaxime alone. Haemolysis test Haemolytic phenotype was tested on blood agar plates (Blood Agar Base number 2; Oxoid, Basingstoke, UK) containing defibrinated sheep erythrocytes 5% v/v. Production of haemolysis was read after overnight incubation at 37°C DNA extraction and sequencing High-quality genomic DNA was extracted from pure pellets of K. pneumoniae subsp. pneumoniae Cow102 using the Quick-DNA fungal/bacterial miniprep kit (Zymo Research) and sent to South Africa Novogene Bioinformatics Technology Co. Ltd. for genome sequencing using the Illumina NovaSeq 6000 instrument. Illumina library was constructed (300-cycle v1.5 kit) and its quality was assessed on the Qubit 2.0 Fluorometer (Thermo Scientific). Genome assembly, annotation, and alignment The quality of sequence reads was determined using FastQC Version 0.12.0 [ 18 ]. Adapter trimming, quality filtering, and per-read quality pruning was performed using fastp software [ 19 ]. The sequence reads were merged using PEAR v0.9.6 [ 20 ]. The filtered paired-end reads were de novo assembled using SPAdes v3.15.3 [ 21 ]. Genome quality and completeness was evaluated using CheckM v1.0.18 [ 22 ] while quality assessment of the assembled sequence was done using QUality ASsessment Tool (QUAST) v5.2.0 [ 23 ]. Genome annotation was performed using the RASTk version 1.073 [ 24 ]. Taxonomic assignment, Multilocus Sequence typing (MLST) and capsular typing Taxonomic classification of the strain was done using kraken2 v2.1.3 [ 25 ] and the Genome Database Taxonomy (GTDB-Tk) v2.3.2 [ 26 ]. High quality genomes from The National Center for Biotechnology Information (NCBI) Reference sequence (RefSeq) database [ 27 ] were retrieved for the calculation of evolutionary distances. Reference genomes closely similar to the cow102 strain were identified by Mash/MinHash algorithm [ 28 ], protein families were identified using Protein Families for the Microbial Genomes database (PATtyFam) [ 29 ]. The protein sequences were aligned using MUSCLE v5 [ 30 ] and the nucleotides for each of those sequences mapped to the protein alignment. The resulting alignments were concatenated into a data matrix for phylogenetic analysis using RaxML v8.2.12 [ 31 ]. Multilocus sequence typing (MLST) of seven housekeeping genes (gapA, infB, mdh, pgi, phoE, rpoB and tonB) was performed by querying the Pasteur Institute ( http://bigsdb.pasteur.fr/klebsiella/klebsiella.html ) [ 32 ] using the MLST v2.220 software [ 33 ]. The Kaptive tool v2.0.4 [ 34 ] was used to determine capsular type (K-type and O-type). Identification of resistance determinants, virulence factors, phages and mobile genetic elements The staramr tool v0.10 [ 35 ] was used to query the current genome against the ResFinder database v4.4.2 [ 36 ] for profiling of AMR genes and drug classes, the plasmidfinder database [ 37 ] for identification of plasmids. Using ABRicate v1.0.1 [ 38 ], virulence determinants were investigated by aligning the reads to the Virulence Factors Database (VFDB) [ 39 ]. ISEScan tool V1.7.2.3 [ 40 ] was used to identify IS elements on the ISFinder database [ 41 ]. Insertion sequence elements shorter than 400 base pairs or single copy IS elements without perfect terminal inverted repeats were not considered. Phages were identified using the PHASTER (PHAge Search Tool Enhanced Release) web tool ( https://phaster.ca/ ) [ 42 ]. Default parameters were used for all tools except otherwise stated. Comparative genome Twenty quality genomes of K. pneumoniae strains of different sequence types isolated from various hosts (chicken, human, pig) and different sources (chicken faeces, open wound, blood, urine, vaginal swab, pork) in Nigeria, one reference genome from the RefSeq database, and one strain that was chosen at random to serve as an outgroup were all obtained from the NCBI database. Description of selected strains is presented in supplementary table S3 . Sequence alignment, pairwise average nucleotide identity (ANI) and sequence alignment percentages was performed using the CLC genomic workbench software v24.0. Thereafter, genome-wide variants were identified using MUMmer4’s DNAdiff tool v4.0 [ 43 ] using the Klebsiella pneumoniae subsp. pneumoniae cow102 assemblies against each NCBI assembly. Structural relocations, translocations, and inversions were identified alongside total and aligned bases. Prior to running the DNAdiff tool, each assembly was filtered to remove contigs of < 1kb in length to prevent short sequences from exaggerating structural variations between assemblies. Ethical clearance According to the Animal Use and Care Committee (AUCC) of the National Veterinary Research Institute (NVRI), Nigeria, the approach used for milk sample was non-invasive and did not cause pain or suffering to the animals, hence no ethical approval was necessary. Quality assurance The genomic DNA used for sequencing was isolated from a single colony of the bacteria. The 16S rDNA gene was extracted from the genome using extractseq version 5.0.0 [ 44 ]. The assessment of potential contamination of the genomic library by allochthonous microorganisms was achieved through BLAST annotation against NCBI microbial 16S database.

One of such examples involve the rising incidence of various species, especially strains of \u003cem\u003eKlebsiella pneumoniae\u003c/em\u003e, acquiring the capability to synthesize extended-spectrum β-Lactamase (ESBL) enzymes that confer resistance to a broad range of β-lactam antibiotics [\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e]. Members of the \u003cem\u003eKlebsiella\u003c/em\u003e genus, a Gram-negative non-motile, encapsulated, facultative anaerobic bacterium, within the family Enterobacteriaceae cause a wide range of infections in both humans and animals. \u003cem\u003eKlebsiella pneumoniae\u003c/em\u003e is a versatile bacterium that can be found in various environments, including the oral cavity, skin, and gastrointestinal tracts of different mammals [\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e]. While normally present as a part of the human microbiota, this bacterium can also act as an opportunistic pathogen, leading to a range of infections such as pneumonia, septicaemia, urinary tract infections, and soft tissue infections, among others [\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eBeta-lactam antibiotics, e.g., penicillins, cephalosporins, monobactams, and carbapenems, which are widely used as therapeutic agents to combat bacterial infections, exert their antimicrobial effects by cleaving to the penicillin-binding protein [\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e]. This binding prevents the biosynthesis of the bacterial cell membrane, ultimately inhibiting the growth and survival of the bacteria [\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e]. However, the presence of ESBLs considerably reduces the efficacy of beta-lactam antibiotics, creating a serious problem in the treatment of infection by ESBL-producing bacteria.\u003c/p\u003e \u003cp\u003eIn recent years, the World Health Organization (WHO) has recognized \u003cem\u003eK. pneumoniae\u003c/em\u003e as being among the top priority pathogens due to the significant morbidity and mortality rates associated with its infections and status as a major worldwide reservoir and vector for antibiotic resistance [\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e, \u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e]. As a result, there is a growing demand for genotyping this important pathogen to better understand its genetic characteristics and transmission patterns. One of the molecular methods commonly employed for this purpose is multilocus sequence typing (MLST) based on housekeeping genes, this allows for the characterization of the genetic relationship between different bacterial strains. \u003cem\u003eKlebsiella\u003c/em\u003e strains are largely oligoclonal [\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e], which means they can be assigned into several unique sequence types (STs). This method of classification provides unambiguous and reliable data, which allows researchers and healthcare professionals gain valuable insights into the genetic diversity and transmission patterns of this pathogen.\u003c/p\u003e \u003cp\u003eIn Nigeria, a significant proportion of the available data that employed molecular techniques to identify \u003cem\u003eKlebsiella\u003c/em\u003e strain is predominantly derived from studies conducted in healthcare facilities and medical settings [\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e, \u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e]. Studying the genomic characteristics of ESBL-producing \u003cem\u003eK. pneumoniae\u003c/em\u003e isolated from alternative sources, such as animal milk, could offer fresh perspectives on the transmission of these opportunistic pathogens across different niches in Nigeria. Moreover, genome typing of \u003cem\u003eKlebsiella\u003c/em\u003e strains from various sources will provide resources for bio-surveillance. This research also contributes to understanding antibiotic resistance dissemination as well as the development of targeted interventions and preventive measures to mitigate the spread of \u003cem\u003eK. pneumoniae\u003c/em\u003e in both animal and human populations.\u003c/p\u003e"},{"header":"Results and discussion","content":"\u003cdiv id=\"Sec3\" class=\"Section2\"\u003e \u003ch2\u003eAntimicrobial susceptibility profile\u003c/h2\u003e \u003cp\u003e \u003cem\u003eKlebsiella\u003c/em\u003e species are major global reservoirs and conduit of drug resistance genes between various bacterial niches [\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e].

The current strain, ST6914 is a triple-locus variant to all closely clustered ST, differing at the phoE, rpoB and tonB loci.

associated with antimicrobial resistance that were not phenotypically tested, and their presence alone does not confirm resistance. These include KatG gene and operons MarA, MarB, and MarR, which are involved in enzymatic catalysis of antibiotics. The BcrC gene serves as a protective protein for antibiotic targets. GdpD and PgsA genes are involved in altering the charge of the cell wall, while OccD6/OprQ and OprB modulate antibiotic permeability. The presence of AcrAB-TolC, EmrAB-TolC, H-NS, and OxyR suggests the role of regulatory factors in modulating the expression of antibiotic resistance genes. Additionally, the genome harbours other ARGs that were acquired through horizontal gene transfer such as the \u003cem\u003eE. coli\u003c/em\u003e UhpT gene, which carries a mutation conferring resistance to fosfomycin, mdfA gene, an efflux pump, and multidrug transporter, as well as the \u003cem\u003eHaemophilus influenzae\u003c/em\u003e PBP3 gene which confers resistance to beta-lactam antibiotics (Fig.\u0026nbsp;2). Comprehensive details of ARGs, their orientation and genomic location is presented in Table \u003cspan refid=\"MOESM1\" class=\"InternalRef\"\u003eS1\u003c/span\u003e.\u003c/p\u003e \u003c/div\u003e

eight IS families: IS1, IS3, IS5, IS110, IS66, IS91, IS630, and ISNCY in the genome of strain Cow102. A comprehensive list of all identified IS, along with their corresponding CDS positions and terminal inverted repeats (TIR) is presented in Table \u003cspan refid=\"MOESM2\" class=\"InternalRef\"\u003eS2\u003c/span\u003e. The only plasmids found in the present genome were IncFIB(K)-1-Kpn3 and Col440I_1. These plasmids were respectively detected in 16 (67%) and 11 (46%) of 24 \u003cem\u003eK. pneumoniae\u003c/em\u003e isolates from powdered milk from Germany [\u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e]. Additionally, five bacteriophages were detected, of which three (Klebsi phiKO2, Escher 500465, Entero cdtI) were intact, one (Salmon 118970 sal3) was incomplete, and one (Escher RCS47) yielded inconclusive results. Figure \u003cspan refid=\"MOESM1\" class=\"InternalRef\"\u003eS1\u003c/span\u003e illustrates the positions of these bacteriophages within the CDS region of the Cow102 strain.\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec10\" class=\"Section2\"\u003e \u003ch2\u003eComparative genomics\u003c/h2\u003e \u003cp\u003eA first glance at the genomic comparison analysis between the current and 22 other strains of \u003cem\u003eK. pneumoniae\u003c/em\u003e suggested a high level of sequence similarity with pairwise average nucleotide identity (ANI) ranging from 99.1\u0026ndash;99.9% (Figure \u003cspan refid=\"MOESM3\" class=\"InternalRef\"\u003eS3\u003c/span\u003e). It is worthy of note that the other strains were from various hosts (chicken, cow, human, pig) and sources (chicken faeces, open wound, blood, urine, vaginal swab, pork, cow milk). Pairwise whole-genome alignments with CLC genomic workbench for all 22 assemblies against the cow102 strain revealed sequence alignment percentages of about 85% and 90% (Figure \u003cspan refid=\"MOESM3\" class=\"InternalRef\"\u003eS3\u003c/span\u003e), despite the fact that huge differences were observed in assembly metrics such as N50 and GC content. A closer look at the variations between the genomes using DNAdiff found significant differences (\u003cem\u003ep\u003c/em\u003e\u0026thinsp;\u0026lt;\u0026thinsp;0.05) in sequence inversions, insertions/deletions (indels), relocations and translocations between the assemblies and the examined strains (Table \u003cspan refid=\"MOESM3\" class=\"InternalRef\"\u003eS3\u003c/span\u003e). The most common structural rearrangements discovered were translocations (x̄=105), which occurred between neighbouring 1-to-1 alignment blocks in different sequences. Additionally, there was an average of approximately nine breaks in the alignment where adjacent 1-to-1 alignment blocks were in the same sequence (relocations), and two somewhat unusual breaks where adjacent 1-to-1 alignment blocks were inverted with regard to each other (inversions). Furthermore, an average of 221 insertion events, three tandem duplication insertion events (TandemIns), 32995 Single Nucleotide Polymorphism (SNPs) and 2629 Single Nucleotide\u003c/p\u003e \u003c/div\u003e"},{"header":"Materials and methods","content":"\u003cdiv id=\"Sec12\" class=\"Section2\"\u003e \u003ch2\u003eBacterial isolation and growth conditions\u003c/h2\u003e \u003cp\u003eThe current report stemmed from a 2019 study that sought to identify functional bacteria in animal milk [\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e, \u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e].

Bacteria were isolated on De-Mann Rogosa Sharpe (MRS) agar plates supplemented with D-Sorbitol and incubation of inoculated plates was performed in anaerobic conditions at 37\u0026deg;C for 24 hours.\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec13\" class=\"Section2\"\u003e \u003ch2\u003eAntimicrobial susceptibility testing and screening of the ESBL production\u003c/h2\u003e \u003cp\u003eAntimicrobial susceptibility testing (AST) was done using the agar diffusion method and the Clinical and Laboratory Standards Institute (CLSI) M100 guideline (31st edition) for drug selection and interpretation of result. Briefly, Mueller\u0026ndash;Hinton agar plates (20ml) were overlaid with MacFarland standardized broth containing the \u003cem\u003eKlebsiella pneumoniae\u003c/em\u003e subsp. \u003cem\u003epneumoniae\u003c/em\u003e strain Cow102. The plates were then treated with a selection of antibiotics from various classes: aminoglycosides (streptomycin [10 \u0026micro;g]) quinolones (ciprofloxacin [5 \u0026micro;g], nalidixic acid [30 \u0026micro;g]) beta-lactams (amoxicillin\u0026thinsp;+\u0026thinsp;clavulanic acid [20/10 \u0026micro;g], ampicillin [10 \u0026micro;g], cefotaxime [30 \u0026micro;g], ceftazidime [30 \u0026micro;g], piperacillin [100 \u0026micro;g]), folic acid synthesis inhibitor (trimethoprim/sulfamethoxazole [1.25/23.75 \u0026micro;g]), monobactams (aztreonam [30 \u0026micro;g]) and other antibiotics (fosfomycin [200 \u0026micro;g], tetracycline [30 \u0026micro;g]). Plates were incubated at 37\u0026deg;C for 24 hours under aerobic conditions, thereafter the diameters of the inhibition zones were measured. The strain was considered susceptible or resistant, using the breakpoints established by CLSI.\u003c/p\u003e \u003cp\u003eESBL-production was suspected due to reduced susceptibility to Ceftazidime (30 \u0026micro;g) and Cefotaxime (30 \u0026micro;g) in the AST. The Combination Disc Test (CDT), as recommended by the CLSI, was employed to confirm the production of ESBL. In summary, clavulanic acid (10 \u0026micro;g) was combined with each of cefotaxime (30 \u0026micro;g) and ceftazidime (30 \u0026micro;g). The test was considered positive when an increase in the growth-inhibitory zone around either the ceftazidime or the cefotaxime disk with clavulanic acid was \u0026ge;\u0026thinsp;5 mm the diameter around the disk containing ceftazidime or cefotaxime alone.\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec14\" class=\"Section2\"\u003e \u003ch2\u003eHaemolysis test\u003c/h2\u003e \u003cp\u003eHaemolytic phenotype was tested on blood agar plates (Blood Agar Base number 2; Oxoid, Basingstoke, UK) containing defibrinated sheep erythrocytes 5% v/v.
