Pitiose intestinal em égua Mangalarga Marchador: relato de caso

Abstract

The Compulsory Supervised Internship (ESO) is a discipline of the Bachelor's Degree in Veterinary Medicine at UFRPE, whose purpose is to provide professional qualification to students and complement the theoretical-practical teaching. The internship was carried out at the Hospital de Cavalos de Paudalho, in the area of surgical and post-surgical of large animals, in the period from 02/03/2020 to 05/19/2020, totaling 420 hours. In addition to describing the experience at ESO, this work aims to report the occurrence of intestinal pythiosis in a mare of the MM breed, who was admitted to the hospital showing signs of colic syndrome. Due to the non-responsiveness to the clinical treatment instituted, it was decided to perform an exploratory laparotomy, an ID segment of approximately 10 cm in length was completely obstructed by a granuloma. Due to the infeasibility of this segment, enterectomy was performed, however, the animal did not resist surgery and there was death after a cardiorespiratory arrest. The opening of the mass revealed material that resembles the “kunkers” found in animals with pythiosis. A sample was sent for histopathology, and the exam was compatible with the clinical suspicion of intestinal obstruction by "kunkers". Pythiosis is an infectious disease, cutaneous-subcutaneous and eventually systemic, caused by the oomycete Pythium insidiosum and affecting humans, domestic and wild animals, with a higher prevalence in horses, a species more exposed to risk factors, and consequently, of greater susceptibility. Several losses are associated with the occurrence of the disease in horses, despite promising studies in diagnostic and treatment methods, advances are needed aimed at understanding the pathogenesis for a better understanding of the development of the clinical forms of pythiosis.
