Bovine Coronavirus Associated Syndromes

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...

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...

A Leaderless Genome Identified during Persistent Bovine Coronavirus Infection Is Associated with Attenuation of Gene Expression

The establishment of persistent viral infection is often associated with the selection of one or more mutant viruses. For example, it has been found that an intraleader open reading frame (ORF) in genomic and subgenomic mRNA (sgmRNA) molecules is selected during bovine coronavirus (BCoV) persistence which leads to translation attenuation of the downstream ORF. Here, we report the unexpected ide...
