“…BRSV infection in calves is widespread in America [20,21] , many European countries [1,8,[22][23][24] and Turkey according to serologic [10,11] and virologic [2] evidence. There is only one study on the investigation with virological methods of BRSV and also other some viruses causing the respiratory disease in calves.…”

Bovine respiratory disease (BRD) causes economic losses related to a reduction in weight gain of affected animals, veterinary treatment costs, death, etc. One of the important respiratory tract disease viruses is the bovine respiratory syncytial virus (BRSV). In this study, it is aimed to report the molecular characterization of detected BRSVs. Therefore, nasal samples from three calves in a herd seen severe respiratory disorders were examined for BRSV and other possible viral etiological agents by PCRs and the amplicons were sequenced. In the phylogenetic tree, BRSV circulating in this herd is clustered with the genetic subgroup III BRSVs deposited in GenBank from some other countries. This study on the molecular characterization of BRSV circulating in calves would contribute for future studies on the epidemiology of this infection and the development and/or choice the effective vaccines in Turkey.

“…Esse tipo de criação facilita a disseminação da doença (PETERHANS et al, 2004), por ter aprisco com baixa ventilação, alta sujidade e superlotação (LAGO et al, 2006;LACASTA et al, 2008;RAHAL et al, 2014). A alta prevalência de PI-3 e BRSV nos rebanhos ovino encontrada neste estudo pode ser resultado deste tipo de criação, onde há contato muito íntimo entre os animais (MANCHEGO et al, 1998;GONÇALVES et al, 2011;CONTRERAS-LUNA et al, 2017).…”

“…No Peru 49,3% dos ovinos apresentavam anticorpos contra RSV (CABELLO;RIVERA, 2006). Estes dados refletem a susceptibilidade de ovinos e à infecção por BRSV devido a uma exposição a fatores predisponentes como condições climáticas, manejo inadequado e estresse(TRIGO, 1987;CONTRERAS-LUNA et al, 2017).O RSV possui tropismo pelo tecido respiratório(LEHMKUHL et al, 1985;VAN DER POEL et al, 1994) e após a penetração nas vias respiratórias o RSV replica-se nas células epiteliais das mucosas nasais, faringe, traqueia e nos pneumócitos tipo II, diagnóstico é baseado na detecção de antígenos virais ou na detecção de anticorpo contra o RSV. Técnicas como a imunofluorescência pode ser utilizada para encontrar antígenos virais em amostras pulmonares.…”

animais doentes. A broncopneumonia envolve vários fatores, incluindo o manejo, agente infeccioso e a imunidade do animal. Por isso, é necessário conhecer todos esses aspectos e associá-los para uma melhor prevenção e tratamento. Palavras-chave: Broncopneumonia. Lavado traqueobrônquico. Lentivírus de pequenos ruminantes. PI-3. Micoplasma. 11 ABSTRACT FRANCO, M. F. Occurrence of respiratory diseases caused by bacteria and viruses in sheep. [Ocorrência de doenças respiratórias causadas por bactérias e vírus em ovinos.]. 2018. 141 f. Dissertação (Mestrado em Ciência) -Faculdade de Medicina Veterinária e Zootecnia, Universidade de São Paulo, São Paulo, 2018.Brazil is the 18th largest producer of sheep meat and, despite being largely informal, is a growing crop in the country. Among the infectious diseases that affect sheep production, bronchopneumonia is one of the most recurrent, however, there are not many studies on this disease in small ruminants in Brazil. Therefore, this research aimed to verify the occurrence of respiratory diseases in the state of São Paulo and Rio de Janeiro caused by bacteria and viruses. For the accomplishment of this project was used tracheobronchial lavage technique transtracheal and collection of whole blood to obtain serum in 99 sheep. These samples were submitted to virus neutralization test to identify antibodies against Parainfluenza Type 3 (PI-3), Bovine Herpesvirus Type 1 (BoHV-1), Bovine Respiratory Syncytial Virus (BRSV) and Bovine Viral Diarrhea Virus (BVDV). Use of the Eradikit ® and agarose gel immunodiffusion test to detect the presence of antibodies against Small Ruminant Lentiviruses (LVPR). Isolation and biochemical identification for M. haemolytica and Pasteurella multocida. Cultivation and isolation, biochemical identification and PCR were used to identify mycoplasmas (Mycoplasma bovis, M. agalactiae, M. mycoides subsp. Capri). Of the 99 samples collected, 33 were from diseased sheep and 66 from healthy sheep. There was no identification of M. haemolytica and P. multocida, nor presence of antibodies against BoHV-1 and BVDV. However, the prevalence of 52.52%, 48.48% and 21.87% of PI-3, BRSV and LVPR, respectively, was observed. In relation to aerobic bacteria, there was a higher frequency of isolation of Bacillus sp. and Gram-negative nonfermenters. Despite identifying Mollicute class bacteria in isolated colonies in 23.28% of the samples, there was only one identification with the oligonucleotides used, M. mycoides subsp. capri, first isolation in sheep in the state of São Paulo and Rio de Janeiro. There was a significant statistical difference (p <0.05) between animals with bronchopneumonia and clinical manifestations such as tachypnea, hyperthermia, nasal secretion, cough, dyspnea, fine crackling and snoring, and between animals with bronchopneumonia and quarantine and separation of diseased animals. Bronchopneumonia involves several factors, including management, infectious agent
