Table 4. S. aureus isolate characteristics for households in which there was concordance of S. aureus spa-types between adult and child participants by industrial hog operation (IHO) and community referent (CR) group, North Carolina, 2014.
Group/household Participant type spa type MLST MRSA MDRSA scn (–) Antibiotic-resistance profile
Note: AMP, ampicillin; CC, clindamycin; CIP, ciprofloxacin; CRO, ceftriaxone; ERY, erythromycin; GAT, gatifloxacin; LVX, levofloxacin; MDRSA, multidrug-resistant S. aureus defined as complete resistance to three or more antibiotic drug classes; MLST, multi-locus sequence type; MRSA, methicillin-resistant S. aureus defined as positive for mecA or mecC; OX, oxacillin; PEN, penicillin; TET, tetracycline; X, the characteristic is present. Antibiotics listed represent distinct drug classes except the beta-lactams (ampicillin, oxacillin, and penicillin) and the quinolones (ciprofloxacin, levofloxacin, and gatifloxacin). Dashes (—) indicate that spa types could not be assigned to MLST based on the scientific literature, analyses of S. aureus isolates collected from our prior livestock worker studies in NC (Nadimpalli et al. 2015; Rinsky et al. 2013), or queries of Ridom SpaServer (http://spa.ridom.de/index.shtml).
