  1. Reduced susceptibility of serotypes to any of the antimicrobial agents tested, calculated both including and excluding cotrimoxazole. Each serotype/group was compared with all other serotypes. ns = not significant *Penicillin, erythromycin, chloramphenicol, cefotaxime, oxacillin, levofloxacin, linezolid, vancomycin.
