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.

El presente artículo de investigación, "Indagación sobre perfiles por competencias profesionales para la comunicación deportiva: un modelo por armar", texto que aborda el estado del arte de la comunicación deportiva en el marco del programa de maestría en Ciencias de la Comunicación, mención Gerencia de la Comunicación, de la División de Estudios para Graduados de la Facultad de Humanidades y Educación de la Universidad del Zulia. Tiene como objetivo central determinar las competencias profesionales para ejercer la comunicación deportiva, así como el modelo pedagógico que en la región zuliana debe acompañar este campo profesional. Está respaldado por teorías desarrolladas por Alcoba (1993), Canquiz e Inciarte (2006) Delgado, además de Tejada y Navío (2005), entre otros. La investigación es de tipo descriptiva, de campo, con un diseño de tipo no experimental, transeccional. El espacio muestral estuvo conformado por seis gerentes de medios de difusión masiva a quienes se les aplicó una entrevista estructurada y por 10 especialistas de la comunicación deportiva en el Zulia, quienes participaron en un grupo focal. Los hallazgos de esta investigación pueden ser aplicados para la formación y el ejercicio de la profesión de los comunicadores dedicados al área deportiva.

This research article, "Inquiry on profiles by professional competences for the sports communication: a model by arming", text that deals with the state of the art of the sports communication in the framework of the master's program in Communication Sciences, management of the communication, the Division of Graduate Studies at the Faculty of Humanities and Education at the University of Zulia. Has as its central goal determine the professional competencies for skill sport, as well as the pedagogical model that in the Zulia Region must accompany this professional field. It is supported by theories developed by Alcoba (1993), Canquiz and Inciarte (2006), in addition to Tejada and Navio (2005), among others. The research is descriptive, field, with a design of type non-experimental,The sample space was composed of six managers of the mass media was applied to them a structured interview, and by 10 specialists in the sports communication in Zulia, who participated in a focus group. The findings of this research can be applied to the training and exercise of the profession of the communicators dedicated to the sports area.

São relatados dois surtos de paralisia progressiva dos membros posteriores em gatos (Felis catus), causada por meningomielite parasitária no Uruguai. Os estudos de casos ocorreram entre os anos 2008 e 2009, respectivamente, nas zonas rurais de Fray Bentos (33º 07' 40,39" S) e foram caracterizados por paralisia dos membros posteriores. Esta paralisia era progressiva e tinha evolução crônica de aproximadamente 12 meses, até que os animais vinham a óbito ou eram eutanasiados. Os sintomas clínicos começaram com ataxia dos membros posteriores, com movimentos laterais, terminado em paralisia total. Em 2009, dois animais foram encaminhados para necropsia. Os achados histopatológicos foram caracterizados por severa mielite na medula espinhal lombar com manguitos perivasculares linfocitarios e necrose da substância branca, severa meningite não supurativa com trombos nos vasos sanguíneos subaracnóideos, e presença intravascular de múltiplos parasitos adultos. De acordo com as características morfológicas dos parasitos e localização nas leptomeninges, este foi identificado como um nematóide da espécie Gurltia paralysans.

Two outbreaks of progressive hind limb paresis in cats (Felis catus) caused by parasitic meningomyelitis in Uruguay are reported. The case studies occurred in 2008 and 2009 respectively, in the rural areas of Fray Bentos (33º 07' 40.39" S) and were characterized by hindquarter paralysis. This paralysis was progressive and had a chronic progression of approximately 12 months until the death or euthanasia of the animals. Clinical symptoms started with ataxia of the hindquarters with lateral side-to-side swaying and culminated in total paralysis. Two animals were sent for necropsy in 2009. The main histopathological findings were severe myelitis in the lumbar spinal cord with perivascular cuffing and white matter necrosis, severe nonsuppurative meningitis with thrombi in subarachnoid blood vessels, and intravascular presence of multiple adult parasites. From the morphological characteristics of the parasites and location in the leptomeninges, the parasite was identified as the nematode Gurltia paralysans.
