Geographic distribution of livestock-associated Staphylococcus aureus in the United States

Abstract Sampling for livestock-associated Staphylococcus aureus (LA-SA) in the United States is haphazard. The diversity of LA- S. aureus in the U.S. appears to be greater than in other countries. We review the epidemiology of LA- S. aureus in U.S. pigs, occupationally-exposed individuals, and environmental samples to assess the diversity and abundance of U.S. LA- S. aureus .
