Bovine papular stomatitis virus (BPSV) is a parapoxvirus associated with and erosive lesions on the muzzle, lips, oral mucosa of cattle. Teats milking cows are occasionally affected, infection frequently transmitted to human beings. The present report describes an outbreak BPSV affecting in midwestern Brazil, involvement. disease was observed neighboring small hand-milking farms, 20 cows. signs included painful reddish papules, ulcers, scabby proliferative teats, clinical course 7–12 days....
The current report describes an outbreak of vesicular disease affecting dairy cows in midwestern Brazil which a coinfection with 2 poxviruses-Vaccinia virus (VACV) and parapoxvirus-was demonstrated. Milking presented vesicles, painful reddish or whitish papules, scabby proliferative lesions the teats udder, clinical course approximately 10-21 days.

Polioencefalomalacia (PEM) de ruminantes é uma doença complexa. O termo indica um diagnóstico morfológico em que necrose neuronal grave resulta amolecimento da substância cinzenta do cérebro. Interpretada no início como única, causada por deficiência tiamina, acredita-se hoje várias causas e diferentes mecanismos patogênicos, ou único mecanismo patogênico disparado agentes, sejam responsáveis pelo aparecimento doença. Neste artigo, as possíveis a patogênese PEM são criticamente revisadas...
ABSTRACT: A retrospective study was conducted on neurological diseases of cattle in the state Goiás, Brazil, from March 2010 to August 2017. Samples three veterinary diagnostic laboratories were analyzed. Diagnosis established 170 out 407 with signs. Epidemiological, clinical, and anatomic pathology features each case researched files. Main disorders included caused by viruses (rabies 29.41%, meningoencephalitis bovine herpesvirus 15.88%, malignant catarrhal fever 1.76%), bacteria (botulism...
Trinta e um casos de polioencefalomalacia (PEM) diagnosticados 1999-2008 em bovinos do Sul (13 casos) Centro-Oeste (18 brasileiros foram estudados. As taxas morbidade (0,04%-6,66 %), mortalidade %) letalidade (50%-100%) semelhantes ambas as regiões estudadas. Não houve uma associação clara entre os PEM a idade, sexo dos sazonalidade. Os ocorreram principalmente criados forma extensiva pastagem. Na Região doença afetou jovens (um ano idade ou menos), enquanto que mais velhos (3 anos mais)...
Implantes biológicos e sintéticos têm sido comumente utilizados em cirurgia experimental com resultados promissores. Esse trabalho tem por objetivo avaliar a viabilidade do compósito de látex, poliamida polilisina 0,1% como implante nas hernioplastias umbilicais recidivantes. Utilizou-se 12 bovinos, mestiços machos (idade 8–10m). As foram efetuadas justaposição sob o anel herniário. Efetuou-se avaliações clínicas diárias, meio escores, segue: processo inflamatório (0-3), deiscência da ferida...

The current report describes granulomatous pneumonia due to Spirocerca lupi in 2 free-ranging maned wolves ( Chrysocyon brachyurus). Both had multiple, white, 1–1.5 cm diameter, soft, encapsulated granulomas the caudal lung lobes, which contained centrally placed parasites on cut sections. Microscopically, there was inflammation with numerous intralesional sections of spirurid nematodes. Representative complete adult specimens nematodes derived from these lesions were submitted for...
Rabies has been an enigmatic disease because microscopic findings in central nervous system tissues do not always correlate well with the severity of clinical illness. Immunohistochemical staining calcium-binding protein calbindin (specifically CbD28k) seems to be technique most used identify Purkinje neurons under normal and pathological conditions. In present work, we evaluated CbD28k immunoreactivity cerebellar cortex natural virus (RABV)-infected cattle. We examined brains from 3 cows 6...
A retrospective study of officially diagnosed poxvirus infections in cattle Distrito Federal (DF), Brazil, between 2015 and 2018 was performed. All cases were investigated by the DF Official Veterinary Service. In most cases, samples oral, cutaneous (teats, udder) or foot lesions submitted to molecular diagnosis PCR. approximately 70% additional also for histopathology. Ninety-three out 2,467 clinically examined (from 385 farms) presented suggestive and/or compatible with poxviruses....

A red, firm 3.5x3.0x3.0cm mass was found within the right lateral ventricle, compressing hippocampus and thalamus of brain a 4-year-old cow. The pituitary enlarged firm. Histologically, both masses consisted moderately pleomorphic epithelial cells arranged as rosettes or sheets supported by delicate fibrovascular stroma. Based on anatomical localization, histopathological immunohistochemical findings, diagnosis choroid plexus carcinoma with metastasis made.
