(a) Clindamycin MICs for the isolates resistant to both clindamycin and erythromycin; MIC range = 0.25–64 mg/L, 73% of strains have MIC ≥ 2 mg/L. (b) Erythromycin MICs for the isolates resistant to both clindamycin and erythromycin; MIC range = 0.5–128 mg/L, 84% of strains have MIC ≥ 2 mg/L. (c) Clindamycin MICs for the clindamycin-resistant isolates; MIC range = 0.25–2 mg/L, 3% of strains have MIC ≥ 2 mg/L. (d) Erythromycin MICs for the erythromycin-resistant isolates; MIC range = 0.5–128 mg/L, 11% of strains have MIC ≥ 2 mg/L.

Correlation between the reported sales of macrolides/lincosamides (MLS) in eight EU countries and the resistance rates to (a) clindamycin, and (b) erythromycin in these countries. By linear regression analysis, the clindamycin and erythromycin resistance rates correlate with the reported sales of MLS ( × clindamycin resistance rates, p < 0.05, r = 0.753; and × erythromycin resistance rates, p < 0.05, r = 0.713, respectively). Solid lines show mean values; dashed lines show 95% confidence intervals.
