Associations between reported work activities and carriage of MDRSA and tetracycline-resistant scn-negative S. aureus CC398 among ILO workersa carrying S. aureus.

ILO = industrial livestock operation.PR = Prevalence ratio.aAssociations among AFLO workers are not presented due to small numbers of reported activities in the group who carried S. aureus.bDue to overlap among tetracycline-resistance, scn-negative, and CC398 isolates and similarity of estimates, we present prevalence ratios and 95% confidence intervals for tetracycline-resistant scn-negative S. aureus CC398.
