Abstract

The objective of the present study was to look for genes encoding for superantigens in bovine coagulase-negative staphylococci (CNS) isolated from milk in Canada. We screened by PCR 71 bovine CNS isolates, obtained from the Mastitis Pathogen Culture Collection managed by the Canadian Bovine Mastitis and Milk Quality Research Network (St-Hyacinthe, QC, Canada), for the presence of 13 superantigen genes. Our results indicate that these CNS isolates did not have any of the 13 superantigen genes screened for in the present study. Thus, prevalence of those genes in CNS from milk is expected to be quite low in Canada.
