RESUMEN.- La pitiosis es una enfermedad ampliamente distribuida a nivel mundial causada por Pythium insidiosum. Esta es transmitida y
propagada en ambientes semiacuáticos afectando principalmente a equinos, caninos, felinos, bovinos y el hombre. En el departamento de Paysandú, Uruguay, en el mes de mayo 2017 se registró un caso de pitiosis en un equino hembra raza Criolla de 24 años. Se realizó la extirpación quirúrgica de una extensa lesión circular ubicada en zona abdominal. Macroscópicamente se observó tejido de granulación, áreas multifocales de necrosis con contenido supurativo hemorrágico, concreciones del tipo pastoso a gredoso de color blanco amarillento. Al examen histopatológico por medio de la tinción de H&E se destacaba ulceración difusa de la epidermis; con severa proliferación de tejido de granulación, abundante tejido conjuntivo, neovascularización, áreas multifocales de necrosis eosinofílica rodeada por abundantes polimorfonucleares, principalmente eosinófilos, y macrófagos en dermis superficial y profunda. Dentro de las áreas de necrosis se observó la presencia de hifas coloreadas positivamente con la coloración argéntica de Grocott. Se obtuvo inmunomarcación positiva para P. insidiosum. En el cultivo del material se aislaron colonias de color blanquecino y crecimiento radial con desarrollo de micelios aéreos luego de 48 horas. Se confirmó el aislamiento de P. insidiosum mediante la
inducción de zooesporas y la caracterización de las mismas. Por medio de la reacción de PCR-anidado se amplificó la región ITS (ITS1, 5.8S, ITS2) y en una segunda reacción se amplió el gen específico para P. insidiosum de la región ITS1. La secuencia obtenida fue comparada con la registrada en el GenBank confirmando una homología de 100 % con P. insidiosum. ---------------- SUMMARY.- Pythiosis is a disease widely distributed worldwide caused by Pythium insidiosum. It is transmitted and propagated in semi-aquatic environments, mainly affecting equines, canines,
felines, cattle and humans. In Paysandú County, Uruguay, in the month of May 2017, a case of pitiosis was registered in a 24-year-old Creole breed female equine. An extensive circular lesion located in the ventral abdominal area was surgically removed. Macroscopically, it was observed granulation tissue, multifocal areas of necrosis with suppurative hemorrhagic content and yellowish-white pasty to chalky concretions. At the histopathological examination with H&E stain there was of notice diffuse ulceration of the epidermis; in superficial and deep dermisthere were severe proliferation of connective tissue, neovascularization, multifocal areas of necrosis surrounded by infiltration of polymorphonuclears, mainly eosinophils, and macrophages. Inside of the areas of necrosis there was presence of hyphae stained positively by the argentic Grocott stain.
Positive immunostaining was obtained for P. insidiosum. In the culture of the fresh material, colonies of whitish color and radial growth were isolated with the development of aerial mycelia after 48 hours. The isolation of P. insidiosum was confirmed by the induction of zoospores and the characterization of them. The ITS region (ITS1, 5.8S, ITS2) was amplified by the nested PCR reaction and in a second reaction the gene specific for P. insidiosum from the ITS1 region was amplified. The sequence obtained was compared with that registered in GenBank confirming a 100% homology with P. insidiosum.

Abstract: Astrovirus species members of the Mamastrovirus genus (family Astroviridae) have been increasingly recognized as neuroinvasive pathogens in various mammals, including humans, mink, cattle, sheep, and pigs. While cases of astrovirus-associated encephalitis have been reported in North America, Europe, and Asia, their presence has never been documented in the Southern hemisphere. This paper describes a case of astrovirus-associated encephalitis in cattle in Uruguay that broadens the geographic distribution and genetic diversity of neuroinvasive astroviruses and provides phylogeographic evidence of viral introduction to the Americas from Europe. A 22-month-old Holstein steer from a farm in Colonia Department, Uruguay developed progressive neurological signs over a 3-days period before dying. Histopathological examination of the brain and proximal cervical spinal cord revealed disseminated, moderate to severe lymphocytic, histiocytic, and plasmacytic poliomeningoencephalomyelitis with neuronal necrosis. A Mamastrovirus strain in the CH13/NeuroS1 clade, that we called bovine astrovirus (BoAstV)-Neuro-Uy, was identified by reverse transcriptase PCR followed by nearly complete genome sequencing. Additionally, BoAstV was detected intralesionally in the brain by chromogenic RNA in situ hybridization within neuronal perikarya, axons and dendrites. Phylogenetic analysis of BoAstV-Neuro-Uy revealed a close relationship to neurotropic BoAstVs within the Virginia/Human-Mink-Ovine clade, which contains a growing cadre of neuroinvasive astroviruses. Analyzing the complete coding region of neuroinvasive BoAstVs sequences available in GenBank, we estimated an evolutionary rate of 4.27 × 10-4 (95% HPD 2.19?6.46 × 10-4) nucleotide substitutions/site/year. Phylogeographic analysis suggests that the common viral ancestor circulated in Europe between 1794?1940, and was introduced in Uruguay between 1849?1967, to later spread to North America and Japan.
