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

Mucosal Immunization with Live Recombinant Bovine Respiratory Syncytial Virus (BRSV) and Recombinant BRSV Lacking the Envelope Glycoprotein G Protects against Challenge with Wild-Type BRSV [PDF]
ABSTRACTRecombinant bovine respiratory syncytial virus (rBRSV) and an rBRSV deletion mutant lacking the G gene (rBRSVΔG) were characterized in calves with respect to replication competence, attenuation, and protective efficacy as live-attenuated BRSV vaccines. Both recombinant viruses were safe and induced protection against a BRSV challenge infection.

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]
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 ...

Detection and Genomic Characterization of Novel Respiratory Viruses in US and Mexican Cattle Farms. [PDF]
Respiratory virus infections in cattle cause an estimated more than $1 billion in production losses and can threaten human health. During February 2024 to May 2025, we employed a One Health approach to surveil for respiratory viruses among cattle, farm workers, and environmental samples from 11 US and Mexican beef or dairy cattle farms.

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