Choroid plexus carcinoma in a cow Ciência Rural
Sant'Ana,Fabiano José Ferreira de; Gabriel,Adriane Loy; Kommers,Glaucia Denise; Barros,Claudio Severo Lombardo de.
A red, firm 3.5x3.0x3.0cm mass was found within the right lateral ventricle, compressing the hippocampus and thalamus of the brain of a 4-year-old cow. The pituitary was enlarged and firm. Histologically, both the brain and pituitary masses consisted of moderately pleomorphic epithelial cells arranged as rosettes or sheets supported by a delicate fibrovascular stroma. Based on anatomical localization, histopathological and immunohistochemical findings, a diagnosis of choroid plexus carcinoma with pituitary metastasis was made.

Bianchi,Ronaldo Michel; Vielmo,Andréia; Schwertz,Claiton Ismael; Cabreira,Adan; Rocha,Jéssica Goulart da; Siqueira,Franciele Maboni; Pavarini,Saulo Petinatti.
ABSTRACT: This study described the pathological and microbiological aspects of a fatal systemic Mortierella wolfii infection in a neonatal calf in southern Brazil. The calf was born clinically normal, but on the third day of life it presented apathy, unilateral hypopyon, and neurological signs, and in the next day it was euthanized. At necropsy, multiple soft, and white-yellow nodules were observed in the liver, spleen, kidneys, mesenteric lymph nodes, heart, and lungs. In the brain, reddish, and friable areas were found. In the eye, there were anterior and posterior synechiae, diffuse thickening of choroid, and anterior chamber filled by whitish and friable material. Microscopically, areas of necrosis, pyogranulomatous inflammation, vasculitis,...

Incidência de brucelose bovina no município de Rio Branco-Acre. Infoteca-e
COSTA, A. L. da; ALENCAR, M. das G. M. de..
A brucelose ou aborto infeccioso é uma doença infectocontagiosa causada pela Parvobactéria do gênero Brucella, cocobacilos imóveis, gram negativos, sem cápsula e sem esporos. Nos bovinos a Brucelose é causada principalmente pela Brucella abortus e menos comumente pela Brucella melitensis e Brucela suis e sua importância econômica é muito grande, pois a produção de bezerros fica reduzida a 40%; a produção de leite decresce em cerca de 20%; de cada cinco vacas que aborta uma fica estéril, favorecendo ainda a incidência de mamites, isto acrescido do fato da doença ser uma zoonose, transmissíel ao homem que bebe leite infectado cru. O aborto ou parto de animais infectados é o fator mais crítico para manutenção do ciclo infeccioso e que cada aborto causado por...

ABSTRACT: Mammary gland neoplasms in cattle are rarely observed in the field veterinary diagnostics routine. Therefore, the objective of this study is to report a metastatic mammary carcinoma in a fourteen-year-old Holstein cow in the state of Santa Catarina, Brazil. The animal was diagnosed by the field veterinarian with clinical mastitis that was unresponsive to treatment, and was euthanized due to the poor prognosis. At the necropsy, multiple yellow, firm, and sometimes friable nodules, ranging from 0.1 to 20cm were observed in all mammary glands, lymph nodes, kidneys, spleen, liver, pancreas, mediastinal lymph nodes, heart, and lungs. The final diagnosis of mammary carcinoma was established through the association of clinical, necropsy,...

Nitrate/nitrite poisoning in dairy cattle from the Midwestern Minas Gerais, Brazil Ciência Rural
Gontijo,Daniel Amaral; Borges,Andressa Afonso; Wouters,Flademir.
ABSTRACT: In a rural property of the Midwestern Minas Gerais, Brazil, three 2.5 to 3-year-old female bovines (7/8 Holstein x 1/8 Gir) weighing approximately 380kg died after showing brownish colored mucosa of conjunctiva and vaginal vestibule, gray-bluish tongue, dyspnea, sialorrhea, tympany, and progression to sternal decubitus and death. In the macroscopic evaluation of one of the bovines, dark (chocolate-colored) blood of difficult coagulation, and intensely cherry-red skeletal and cardiac musculature were observed. Beyond that were observed brownish lungs, kidneys, liver, and encephalon, and all the stomach compartments were dilated due to large amounts of gas. In addition, the carcass exhaled a nitrous odor. The diphenylamine test and the nitrate...

Retrospective study of Bovine herpesvirus 5 meningoencephalitis in cattle from São Paulo State, Brazil Arq. Bras. Med. Vet. Zootec.
Cagnini,D.Q.; Andrade,D.G.A.; Cunha,P.H.J.; Oliveira-Filho,J.P.; Amorim,R.L.; Alfieri,A.A.; Borges,A.S..
ABSTRACT Meningoencephalitis caused by Bovine herpesvirus 5 (BoHV-5) is an important neurological disease that affects Brazilian cattle herds. The present study investigated the presence of BoHV-5 DNA in cattle diagnosed with meningoencephalitis at Faculdade de Medicina Veterinária e Zootecnia, UNESP - Univ Estadual Paulista from 1980 to 2009. The records obtained from the Large Animal Internal Medicine Service and the Animal Pathology Service were reviewed to identify clinical and epidemiological data from cattle with neurological signs. Excluding rabies cases, we found 115 cases of cattle with neurological signs that had been necropsied. Non-suppurative meningoencephalitis was diagnosed in 28 animals of the 115 initially selected based on...
