a
Strains indicated by asterisks have susceptibilities to selected antimicrobials, as indicated under “Antimicrobial resistance profile.” NCSU designations are those used in a previous study (17).
b
Age categories 1, 2, 3, and 4 correspond to 1 to 2 weeks, 3 to 4 weeks, 5 to 7 weeks, and 8 to 21 weeks, respectively.
c
Strains were resistant to the indicated antimicrobials. C/N, ciprofloxacin/nalidixic acid; K, kanamycin; S, streptomycin; T, tetracycline; E, erythromycin.
