Epidemiological Investigation and Phylogenetic Analysis of Bovine Respiratory Disease Complex in Northern China. [PDF]

Vet Med Sci
First comprehensive epidemiological and phylogenetic study of bovine respiratory disease complex (BRDC) in northern China (2022–2024). Dominant viral pathogens (BVDV, BPIV‐3) show winter seasonality and co‐infections with Mycoplasma bovis. Chinese isolates share evolutionary links with global strains, highlighting cross‐regional pathogen transmission ...

Assessment of Risk Factors Related to Environmental Factors and Herd Management for Bovine Respiratory Syncytial Virus and Bovine Parainfluenza Virus-3 Infections Frequently Observed in Beef and Dairy Cattle. [PDF]

Vet Med Sci
In this study, molecular diagnosis of BRSV and BPIV3 factors was aimed and risk factors were tried to be determined by considering ‘environmental factors’, ‘herd management factors’ and ‘infection‐related factors.’ RT‐PCR technique was used for the molecular detection of pathogens and multivariate and univariate statistical analyses were performed ...

First Detection and Genomic Characterization of Feline Orthopneumovirus From Domestic Cats in South Korea. [PDF]

Transbound Emerg Dis
Orthopneumoviruses have been found in humans and various animal hosts, including mice, cattle, dogs, and swine, in several countries, but have rarely been found in cats, with the only report being from the United States in 2010. This study is the first to detect feline orthopneumovirus (FPnV) in domestic cats in South Korea and the first to ...

Thoracic Ultrasonography Findings and Their Association With Respiratory Pathogens in 221 Young Beef Cattle at Fattening Farms: A Cross-Sectional Study. [PDF]

J Vet Intern Med
ABSTRACT Background Thoracic ultrasonography (TUS) could improve antibiotic treatment selection in cattle with respiratory diseases. Hypothesis/Objectives Evaluate the association between respiratory pathogens and consolidations on TUS in feedlot cattle, at both individual and group levels. Animals A total of 221 bulls, aged 8.8 months and weighing 322.

Efficacy of Bovine Respiratory Syncytial Virus Vaccines to Reduce Morbidity and Mortality in Calves Within Experimental Infection Models: A Systematic Review and Meta-Analysis

Frontiers in Veterinary Science, 2022
Producers and veterinarians commonly use vaccination as the main strategy to reduce the incidence of bovine respiratory syncytial virus (BRSV) infection in calves; however, supportive evidence of BRSV vaccination efficacy has been inconsistent in the ...

Detection of antibodies against bovine respiratory syncytial virus (BRSV) in dairy cattle with different prevalences of bovine herpesvirus type 1 (BoHV-1) in São Paulo State, Brazil/
Detecção de anticorpos contra o vírus respiratório sincicial bovino (BRSV) em rebanhos leiteiros com diferentes prevalências de herpesvirus bovino tipo 1 (BoHV-1) no Estado de São Paulo, Brasil

Semina: Ciências Agrárias, 2011
Serum samples from three dairy farms classified as high (1, 78.6%), medium (2, 40.0%) and low (3, 1.6%) prevalence for bovine herpesvirus type 1 (BoHV-1) from São Paulo State, were collected to analyze the prevalence to the bovine respiratory syncytial ...
