In Belgium, decreasing macrolide, lincosamide, streptogramins B, and tetracycline use during 1997-2007 correlated significantly with decreasing macrolide-resistant Streptococcus pyogenes during 1999-2009. Maintaining drug use below a critical threshold corresponded with low-level macrolide-resistant S. pyogenes and an increased number of erm(A)-harboring emm77 S. pyogenes with low fitness costs.
在比利时,1997 年至 2007 年间大环内酯类、林可酰胺类、链阳菌素 B 和四环素类药物的使用减少,与 1999 年至 2009 年间耐大环内酯类肺炎链球菌的减少显著相关。将药物使用量维持在临界阈值以下,与低水平的耐大环内酯类肺炎链球菌以及具有低适应成本的 erm(A) 携带 emm77 型肺炎链球菌数量增加有关。
