Prevalence, characterization, and antimicrobial resistance of Listeria monocytogenes isolates from bovine hides and carcasses

Abstract

Listeriamonocytogenes isolates frombovine hides and carcasses (n=812) weremainly of serogroup 1/2a. All strains were positive for internalin genes. Several isolates were resistant to oxacillin (72.2%) or clindamycin (37.0%). These findings indicate that L. monocytogenes of beef origin can be considered a public health concern. © 2012, American Society for Microbiology.
