Proportion of children with nasopharyngeal carriage of pneumococcal serotypes and antimicrobial non-susceptible serotypes, 7PCV and 23PPV serotype group. A: 2003. B: 2005. Serogroups: Left – 7PCV serotypes. Middle – 23PPV serotypes. Right – non-23PPV serotypes. MacR (yellow): azithromycin MIC ≥ 2 μg/mL. PenR (mauve): penicillin MIC ≥ 0.12 μg/mL. Strains with resistance to both beta-lactam and macrolide antibiotics were included in each category. (in 2003 six of 38 6B isolates, two of 25 23Bs and one of 50 11As; in 2005 one of 39 23B isolates and one of 37 11As.)
