13. Aspectos clínico-patológicos da paratuberculose em rebanho bovino leiteiro no município de Rio Claro, RJ. / Clinic-pathological aspects of paratuberculosis in dairy cattle in Rio Claro county, Rio de Janeiro State.
The epidemic and clinic-pathological aspects of paratuberculois in a dairy cattle herd in the Rio Claro county, southern Rio de Janeiro region, are described. In the years 2006-2009, eight adult cows presented chronic-intermittent diarrhea, chronic weight loss and normal appetite. At necropsy, the subserosal lymphatics were proeminent and dilated, mesenteric

14. Molecular analysis of the bovine coronavirus S1 gene by direct sequencing of diarrheic fecal specimens
Bovine coronavirus (BCoV) causes severe diarrhea in newborn calves, is associated with winter dysentery in adult cattle and respiratory infections in calves and feedlot cattle. The BCoV S protein plays a fundamental role in viral attachment and entry into the host cell, and is cleaved into two subunits termed S1 (amino terminal) and S2 (carboxy terminal). Th

15. Recombinant E2 glycoprotein of bovine viral diarrhea virus induces a solid humoral neutralizing immune response but fails to confer total protection in cattle
Two recombinant baculoviruses were produced in order to obtain a bovine viral diarrhea virus (BVDV) immunogen: AcNPV/E2 expressing E2 glycoprotein, and AcNPV/E0E1E2 expressing the polyprotein region coding for the three structural proteins of BVDV (E0, E1, and E2). Mice were immunized with Sf9 cells infected with the recombinant baculoviruses in a water in o

16. Disenteria de inverno: detecção de coronavírus bovino (BCoV) por reação de PCR dirigida ao gene Rp Rd e isolamento em cultivo celular de HRT-18G / Winter dysentery: detection of bovine coronavirus (BCoV) by RT-PCR for the Rp Rd gene and isolation in monolayers of HRT-18G cells
Bovine coronavirus (BCoV), a member of Coronaviridae family, causes severe diarrhea in newborn calves and has been associated with outbreaks of winter dysentery (WD) in adult cattle in several countries, including Brazil. The morbidity rate of WD is very high (50-100%) and the disease causes severe economic losses once it decreases milk production. The aim o

17. Produção e avaliação de plasma bovino desidratado como ingrediente de rações de leitões desmamados precocemente. / Production and evaluation of plasma dehydrated as an ingredient in cattle rations of early weaners.
The objective of this work was to obtain spray dried bovine plasma (SDBP) and to compare it with a commercial one (CSDBP) as feed ingredients of weanling pigs (weaned at 21 days of age) based on performance, blood and plasma components, liver and spleen glutathione levels, small intestine morphology and diarrhea score. Blood of healthy bovines was collected

18. ABLAÇÃO CIRÚRGICA DOS BULBOS OLFATÓRIOS EM COELHOS: MODELO PARA ESTUDOS DE PATOGENIA DE INFECÇÕES POR VÍRUS NEUROTRÓPICOS / SURGICAL ABLATION OF THE OLFACTORY BULB IN RABBITS: A MODEL TO STUDY THE PATHOGENISIS OF NEUROTROPIC VIRUS INFECTIONS.
Rabbits have been used as animal models to study the pathogenesis of neurological infection by bovine herpesvirus type 5 (BHV-5), an important agent of meningoencephalitis in cattle. The olfactory system has been implicated as the main pathway for the virus to reach the brain after replication in the nasal mucosa. To investigate the role of the olfactory rou

19. Caracterização de um novo fator de colonização (FC O25) de Escherichia coli isoladas de colibacilose neonatal bovina / Characterization of a new colonization (CF O25) of Escherichia coli isolated from neonatal bovine colibacillosis
Infections from Escherichia coli are frequent in domestic animals, affecting mainly newborn animals in the post weaning period, being thus responsible for important economic losses in the cattle, porcine and lamb herds. The establishment of the bacterium in the host is made by colonization and it is a process mediated by proteins called adhesins that are dis

20. Diagnóstico molecular e análise de polimorfismos do gene S1 de estirpes brasileiras do coronavírus bovino em fezes diarreicas de bezerros naturalmente infectados
O coronavírus bovino (BCoV) é um importante agente etiológico de diarréia neonatal em bezerros. Usualmente, as técnicas para a detecção do BCoV limitam-se a métodos de baixa sensibilidade como ensaios imunoenzimáticos e testes de hemaglutinação (HA)/ inibição da hemaglutinação (HI). Embora a PCR seja altamente sensível e específica, a nature

21. Caracterização molecular de isolados de Escherichia coli verotoxigênica obtidos de bovinos sadios em Pelotas, RS / Molecular caracterization strains of Verotoxin - producing Escherichia coli isolates obtained healthy cattle in Pelotas Sourthen Brazil
Verotoxin-producing Escherichia coli (VTEC) strains are know to cause a variety of human diseases like mild diarrhea, Hemorrhagic Colitis (HC), and Hemolytic Uremic Syndrome (HUS). In this study the PCR technique was used to detect vt1, vt2 and eae genes, that encod two verotoxin and a adhesion, respectively. A total of 139 strains isolated from 47 healthy c

22. Caracterização de amostras de Escherichia coli isoladas de bezerros com e sem diarreia : pesquisa de fatores de colonização e toxinas / Characterization of Escherichia coli strains isolated of diarrheic and healthy calves : a colonization factors and toxins study
Infections caused by Escherichia coli are the most cause of diarrhea in animals, bovines and cattle, being thus responsible for important economic losses in farms. In this work, 58 strains isolated from calves with diarrhea and 43 strains isolated from healthy calves were studied for PCR analysis about the virulence factors eae, EAF, K99, F41, CS31A, F17, ST

23. Impacto de doenças reprodutivas e do manejo sobre a produção e reprodução em rebanhos bovinos leiteiros na região de Guaratinguetá / SP.
The study aimed to investigate possible causes of the increased calving interval (PI) of 29 dairy cattle in the region of Guaratinguetá-SP from 202-2003 and make an assessment of losses owing to the higher IP, such as lower production milk and reduction of the birth of calves in the properties. We searched for antibodies Bricelose, leptospirosis, infectious

24. Diagnóstico da infecção pelo vírus da diarréia viral bovina em propriedades da microrregião de Viçosa / Diagnosis of bovine viral diarrhea virus infection in herds of microregion of Viçosa
The Bovine Viral Diarrhea Virus (BVDV) belongs to the family Flaviviridae and it is a member of the genus Pestivirus. BVDV has a worldwide distribution and infection in cattle is common, which is evidenced by a high level of seropositive animal in the infected population. The major economical damage caused by BVDV in susceptible herds is still caused by intr
