“…Apart from the affected organs in this case, histopathological MEED lesions have also been described in the lungs, liver, salivary glands, esophagus, kidneys, and biliary epithelium (NIMMO WILKIE et al, 1985;BOSSELER et al, 2013;MAULDIN & PETERS-KENNEDY, 2016). Histologically, MEED should be differentiated from equine intestinal pythiosis, since infection by Pythium insidiosum can induce a pyogranulomatous and eosinophilic enteritis that contains foci of necrosis (BEZERRA JÚNIOR et al, 2010). The diagnosis of equine intestinal pythiosis was excluded in this horse, because no fungal structures were observed on GMS-stained slides of tissue specimens.…”

Equine multisystemic eosinophilic epitheliotropic disease (MEED) is a rare disease, characterized by eosinophilia and eosinophilic infiltration of several organs. A 5-year-old horse presented pruritus, areas of alopecia, and moderate eosinophilia. The horse was treated with corticosteroids and antibiotics without substantial improvement; and after the disease progressed to fever, diarrhea, gastric reflux and progressive weight loss. Due to poor prognosis the horse was euthanized. Necropsy revealed poor body condition, multiple to coalescing foci of alopecia, with epidermal ulcerations and crusts on the head and distal parts of the limbs. The proximal duodenum was enlarged, with 3 intraluminal nodules. Histopathological evaluation revealed eosinophilic granulomas in the skin, oral mucosa, duodenum, pancreas, and mesenteric lymph nodes, which were associated with infiltrates of eosinophils, lymphocytes, macrophages, multinucleated giant cells, and occasional plasma cells, along with fibrovascular connective tissue proliferation. MEED should be included in the differential diagnosis of horses with skin lesions concomitant with clinical signs of gastrointestinal illness.

“…Pyogranulomatous gastroenteritis caused by Pythium insidiosum has been described in horses (Bezerra Júnior et al, 2010), sheep (Pessoa et al, 2012), cats (Rakich et al, 2005) and dogs (Galiza et al, 2014;Fujimori et al, 2016). However, we did not find any reports of enteric pythiosis resulting in intestinal intussusception in Veterinary Medicine literature.…”

We report a case of intestinal intussusception secondary to enteritis caused by Pythium insidiosum infection in a 1-year-old mixed breed bitch that died after a 30-day history of bloody diarrhea, anorexia, weight loss, listlessness, dehydration, and pale mucous membranes. Necropsy revealed two areas of intussusception, one jejunum-jejunal and one ileum-cecum-colic. The first intussusception showed slight congestion of the intestinal loop, which was resolved by manual traction, while the second intussusception exhibited thickening, irregular yellow spots, and transmural congestion. Histologically, the jejunum-jejunal segment had ischemic lesions secondary and ileum-cecum-colic intussusception there was also necrotizing, pyogranulomatous enteritis associated with negative images of intralesional fungal hyphae that were well visualized by silver impregnation. Immunohistochemistry identified the hyphae as Pythium insidiosum. The diagnosis was made based on the histological changes and confirmed by immunohistochemistry. We can conclude that enteritis by P. insidiosum in dogs can occasionally cause intestinal intussusception and result in acute death.

“…Los zoósporos enquistados secretan una sustancia amorfa que permite su adherencia a la piel y a plantas, y cuando son fijados a la piel producen filamentos en forma de hifas que penetran en esta y en los tejidos adyacentes (25,26). Por otra parte, se informa que no existe predisposición de raza, sexo, edad o necesidad de solución de continuidad (porta de entrada) para la infección y el consecuente desarrollo de la enfermedad, debido…”

ResumenEl objetivo de este estudio fue evaluar y caracterizar los aspectos clínicos e histopatológicos de la pitiosis cutánea en burros (Equus asinus) en el departamento de Córdoba, Colombia. Se realizó un estudio de tipo descriptivo, no probabilístico en animales de conveniencia. Fueron analizados nueve burros con pitiosis cutánea diagnosticados clínica e histopatológicamen-te. Al describir los casos se observó una grave ulceración granulomatosa en forma de cráter, con tejido necrótico, apariencia tumoral, abundante exudación filante fibrino-sanguinolenta y salida de material caseificado de color blanco amarillento denominado kunkers. Las lesiones se ubicaron en miembros, abdomen ventral y pecho de los animales. Histopatológicamente, con la coloración de hematoxilina-eosina, se observó dermatitis piogranulomatosa severa, con abundante infiltrado inflamatorio de tipo eosinofílico y neutrofílico; con la coloración de Grocott se evidenciaron hifas con tabiques y parcialmente ramificadas en ángulo recto, de color café. El diagnóstico definitivo de la enfermedad se fundamentó en las características clínicas, el diagnóstico diferencial y en los hallazgos histopatológicos. Fue concluyente el diagnóstico de la pitiosis cutánea. El presente estudio se convierte en el primer reporte de esta enfermedad en burros (Equus asinus) en el departamento de Córdoba y en Colombia.Palabras clave: pitiosis cutánea, burros. Clinical and Histopathological Evaluation of Cutaneous Pythiosis in Donkeys (Equusasinus) AbstractThe purpose of this study was to evaluate and characterize the clinical and histopathological aspects of cutaneous pythiosis in donkeys (Equus asinus) in the Department of Cordoba, Colombia. A descriptive, non-probability study was conducted on domesticated animals. Nine donkeys clinically and histopathologically diagnosed with cutaneous pythiosis were analyzed. After describing the cases, a serious, crater-shaped granulomatous ulcer was observed, with necrotic tissue, a tumor appearance, abundant fibrinous-bloody exudation and yellowish-white caseous material known as kunkers. The lesions were found in the members, ventral abdomen and chest of the animals. Histopathologically, with the hematoxylin-eosin staining, severe pyogranulomatous dermatitis was observed, with abundant eosinophilic and neutrophilic inflammatory infiltrate; with the Grocott staining, hyphae with septa were found, partially branching into a right angle and brown in color. The definitive diagnosis of the disease was based on the clinical features, the differential diagnosis and the histopathological findings. The diagnosis of cutaneous pythiosis was conclusive.
