Pythiosis mamaria en una yegua criolla colombiana

A case is reported of a Colombian Creole mare, brown, 7 years old and weighing 300 Kg, which was treated by the Outpatient Clinical Service of the Large Animal Medical-Surgical Clinic area of ​​the University of Córdoba. The anamnesis indicates that the mare presented a progressive increase in size at the level of the mammary gland, with constant mucopurulent discharge from different orifices, likewise the owner reports that he made incisions to facilitate the drainage of material from the mammary gland, since he thought that this increase consisted of an abscess, in the same way, the application of antibiotics based on tetracyclines and non-steroidal anti-inflammatory drugs reported. At the clinical examination, the presence of a granulomatous lesion that compromised the entire mammary gland was determined, with the presence of several crater-shaped openings and exit of fibrinopurulent material, upon compression I presented an exit of a greater amount of secretion, as well as caseified masses called Kunker. It was decided to perform a total mastectomy as a control measure and to extend the life of the mare. During the surgical procedure under general anesthesia, the presence of abundant granulomatous tissue was evidenced, as well as the presence of large amounts of kunkers accumulated in cavities caused by the invasion of Pythium insidiosum in the granular tissue. The importance of knowing the epidemiology of Pythiosis is concluded, being relevant the location of clinical cases at the mammary gland level in Colombian Creole mares exposed to risk factors.
