Four (5%) of 81 recent isolates of Streptococcus pneumoniae from the blood of adult patients but no isolates from pediatric patients (n = 51) were resistant (MIC, > or = 1 microgram/ml) to erythromycin. The MICs of clarithromycin were slightly lower than those of erythromycin, but there was complete cross-resistance. Routine testing and surveillance are needed to determine whether erythromycin resistance among S. pneumoniae isolates is increasing throughout the United States.
在近期从成年患者血液中分离出的81株肺炎链球菌中,有4株(5%)对红霉素耐药(MIC≥1微克/毫升),但儿科患者(n = 51)中分离出的菌株未出现耐药情况。克拉霉素的MIC略低于红霉素,但存在完全交叉耐药。需要进行常规检测和监测,以确定美国各地肺炎链球菌分离株对红霉素的耐药性是否正在增加。
