Bovine Respiratory Coronavirus

Antigenic relationships among proteins of bovine coronavirus, human respiratory coronavirus OC43, and mouse hepatitis coronavirus A59.

Antisera prepared against each of three single and one pair of major structural proteins of the bovine coronavirus (Mebus strain) were used in immunoblotting studies to measure cross-reactivity with the structural proteins of the human coronavirus OC43 and the mouse hepatitis coronavirus A59. We conclude that the bovine coronavirus is comprised of four major structural proteins, gp190 (normally...

Bovine Coronavirus and Bovine Respiratory Syncytial Virus Infections in Dairy Herds Prospects for Control

Bovine coronavirus (BCV) and bovine respiratory syncytial virus (BRSV) are significant causes of enteric and respiratory disease in cattle throughout the world. The aim of this thesis was to gain further knowledge of the epidemiology of these infections in Swedish dairy herds. Two studies were conducted of the association between BCV/BRSV antibody status and health and performance, on herd (79 ...

Bovine respiratory syncytial virus and bovine coronavirus in Swedish organic and conventional dairy herds

BACKGROUND Infections with bovine respiratory syncytial virus (BRSV) and bovine coronavirus (BoCV) are endemic to the cattle populations in most countries, causing respiratory and/or enteric disease. It has been demonstrated that herds can remain free from these infections for several years also in high prevalence areas. Organically managed (OM) dairy herds have been shown to have lower seropre...

Bovine coronavirus structural proteins.

The tissue culture-adapted strain (Mebus) of bovine coronavirus was grown in the presence of isotopically labeled amino acids, glucosamine, or orthophosphate for the purpose of analyzing the virion structural proteins. Five species of polypeptides were identified when purified virions were solubilized in urea and sodium dodecyl sulfate and resolved by polyacrylamide gel electrophoresis. Four sp...
