The frequency of Neospora spp., Leptospira spp. and Brucella abortus infections in adult cattle was determined herds the State Pará, Brazil, which is an important region for production located Amazon region. A total 3466 female from 176 were tested, leading to a seropositive animals 14.7%, 3.7% 65.5% herd positivity 87.4%, 41.3% 98.8% caused by B. respectively. five most frequently diagnosed serologic responses those against serovars hardjo, wolfii, grippotyphosa, hebdomadis shermani....
Abstract Bluetongue (BT), caused by virus (BTV), is a disease that affects ruminants such as cattle, sheep, goats and deer. BTV transmitted female midges of the genus Culicoides . In Brazil, information on prevalence in cattle limited, so objective this work was to identify serotypes cattle. The State São Paulo divided into seven cattle‐producing regions, each them, 300 farms were randomly selected. One animal from farm (out total 1,598 farms) selected its sera tested neutralization...
ABSTRACT The seroprevalence of Maedi-Visna in sheep from Aracatuba region – SP, was determined and correlated to age, gender, breed, or production systems. Blood samples were collected 444 sheep, aging two 12 year-old. Both sexes different breeds sampled 20 farms this region. Physical examination performed all animals. Agar gel immunodiffusion test kit used diagnose serum samples. Twelve animals, five farms, AGID positive, yielding a 2.7%, with no correlation among systems the detection...
Meningoencephalitis by Herpesvirus type 5 (BoHV-5) in cattle has some features that are similar to those of herpetic encephalitis humans and other animal species. Human 3 (commonly known as Varicella-zoster virus 1), herpes simplex viruses (HSV), equid 1 (EHV-1) induce an intense inflammatory, vascular cellular response. In spite the many reports describing histological lesions associated with natural experimental infections, immunopathological mechanisms for development neurological...
Bovine Viral Diarrhea Virus (BVDV) and Herpesvirus type 1 (BoHV-1) cause reproductive problems in cattle restrictions on international trade animals worldwide. Both infections were detected herds the Paraíba state, Northeastern Brazil, however, spatial distribution geographic identification of positive for these viruses has never been examined. Therefore, aim this study was to describe pattern apparent prevalence estimate identify clustering BVDV BoHV-1 from state Paraíba, Brazil. The...
Glanders is an equine zoonosis caused by Burkholderia mallei that responsible for considerable economic loss. Complement fixation testing (CFT) using warm or cold incubation are recommended the OIE, but many routinely used detection tests may present misleading results. To increase accuracy of glanders diagnosis and establish appropriate protocol in collaboration with National Equine Health Program, seven horses positive kept isolation Brazil were examined fortnightly CFT, microbiological...
O presente trabalho teve por objetivo avaliar a patogenicidade e virulência do isolado IBCB66 de Beauveria bassiana para larvas Rhipicephalus (Boophilus) microplus.O foi utilizado como padrão, com finalidade determinar CL50 (Concentração Letal), CL90, TL50 (Tempo Letal) TL90.O testado em seis concentrações diferentes (5 × 10 6 , 7 5 8 9 ) porcentagem mortalidade.A mortalidade total observada 18 dias após o início teste no grupo tratado
ABSTRACT: Bovine respiratory disease (BRD) is responsible for economic losses in cattle production. Viruses are categorized as primary etiological agents. The aims of this study were to evaluate the presence antibodies against bovine viral diarrhea virus (BVDV), herpes type 1 (BoHV-1), and syncytial (BRSV) healthy BRD calves from family farming relation clinical signs BRD. Hundred forty-five randomly selected physical examination was performed. Only 123 animals classified calves. Antibodies...
Barbary sheep (Ammotragus lervia) have the potential to act as hosts of important infectious diseases, particularly zoonoses. Blood samples from 17 at Curitiba zoo were collected evaluate occurrences anti-Toxoplasma gondii and anti-Neospora caninum antibodies, tested using indirect immunofluorescence antibody test (IFAT). Anti-T. anti-N. antibodies detected in 4/17 (23.5%) samples, respectively. The present study has shown that exposed T. andN. therefore may intermediate hosts, spreading...
This study was carried out to select isolates of the entomopathogenic fungus Beauveria bassiana with pathogenic potential control Rhipicephalus (Boophilus) microplus tick.The effectiveness thirty first tested at a concentration 5 × 10 8 conidia.mL - .Of these, eight were evaluated (IBCB01, IBCB02, IBCB07, IBCB17, IBCB21, IBCB74, IBCB149, IBCB165) and showed an between 90 99%; thirteen (IBCB03, IBCB14, IBCB16, IBCB24, IBCB95, IBCB97, IBCB102, IBCB141, IBCB146, IBCB147, IBCB150, IBCB154,...
The aim of this study was to carry out the serological occurrence Maedi-Visna virus (MVV) and CAE (CAEV) in ovines caprines breeding São Paulo state. test detect MVV CAEV antibodies agar gel immunodiffusion (AGID). detection against 0,3% (4/1235) 15,1% (30/199). Was carried analysis risk factors associated with presence positive property for Maedi-Visna. Variables were selected both diseases, however, when these variables used multivariate logistic regression model not identified infections....
Bluetongue (BT) is considered endemic in several regions of Brazil. The State Sao Paulo was divided into 7 cattle production (circuits) according the different systems breeding, operational and logistical capacity state veterinary service. At least 1 animal from each property (a total 1,716 farms) tested by competitive ELISA for presence antibodies against BTV. Sero‑positive sera were subsequently also virus neutralization tests (VNT) using serial dilutions 1:10 (cutoff) up to 1:640 (in...
A cross-sectional study was carried out to determine the flock-level seroprevalence of Caprine herpesvirus 1 (CpHV-1) and Bovine (BoHV-1) 2 (BoHV-2) risk factors associated with CpHV-1 in dairy goat flocks from a semiarid region northeastern Brazil. total 1,034 serum samples 110 were collected March 2009 through 2010. structured questionnaire focusing on variables related for infection given each farmer at time blood collection. Antibodies against CpHV-1, BoHV-1, BoHV-2 detected by...
Dentre as doenças que acometem os equídeos, enfermidades virais assumem um papel importante do ponto de vista sanitário e econômico, especialmente a influenza, arterite viral, infecções herpéticas estomatite vesicular. Na literatura nacional, existe pouco ou nenhum relato sobre ocorrência infecciosas nos asininos. Tendo em importância dos asininos para diferentes atividades falta informações esses animais, este trabalho teve como objetivo estudar frequência anticorpos anti-EHV, antivírus da...
ABSTRACT: Bluetongue is an infectious, non-contagious disease that affects domestic and wild ruminants, caused by a virus from the Orbivirus genus, Reoviridae family, transmitted arthropod vectors of Culicoides genus.

Among all possible causes of disease, viruses are commonly categorized as primary etiological agents. The present study aimed to identify the presence parainfluenza type 3 virus and Influenza D (IVD) tracheobronchial fluid samples healthy calves showing clinical signs disease. Samples were collected from 42 farming farms São Paulo State, Brazil. A total 141...
