Although numerous reports on bacteriophages for staphylococci of human origin have appeared, none could be found regarding phages active against staphylococci from bovine sources. This laboratory has been concerned with various phases of bovine mastitis, hence it was of interest to investigate the occurrence and role of bacteriophage in staphylococcal mastitis. While this type of mastitis is pr...

Coagulase-negative staphylococcal species are a common cause of subclinical bovine mastitis, with Staphylococcus chromogenes being one of the most frequently identified species in these cases. The draft genome sequence of an S. chromogenes isolate (MU 970) recovered from the milk of a cow with a chronic intramammary infection is reported here.

Common viral antigens were detected, by fluorescent-antibody studies, in cells infected with herpes simplex virus 1, squirrel monkey herpesvirus 1, bovine rhinotracheitis, and equine abortion viruses. The two primate viruses showed slight cross-neutralization.

The alphaherpesvirus tegument protein VP22 has been characterized with multiple traits including microtubule reorganization, nuclear localization, and nonclassical intercellular trafficking. However, all these data were derived from studies using herpes simplex virus type 1 (HSV-1) and may not apply to VP22 homologs of other alphaherpesviruses. We compared subcellular attributes of HSV-1 VP22 (...

Bovine respiratory disease complex (BRDC) is the major cause of serious respiratory tract infections in calves. The disease is multifactorial, with either stress or reduced immunity allowing several pathogens to emerge. We investigated the susceptibility of bovine airway epithelial cells (BAEC) to infection by the three major viruses associated with the BRDC: bovine respiratory syncytial virus ...
