We tested in vitro 49 isolates of Chlamydia pneumoniae obtained from 35 children with community-acquired pneumonia against clarithromycin and erythromycin. The children were part of a treatment study comparing the two drugs. Clarithromycin was 2- to 10-fold more active than erythromycin, with a MIC for 90% of strains tested and minimal chlamydiacidal concentration for 90% of strains tested of 0.031 microgram/ml compared with 0.125 microgram/ml for erythromycin. Eight of these children, two of whom were treated with erythromycin and six of whom received clarithromycin, remained culture positive after treatment. We were able to test 21 isolates from these children. All were susceptible to both drugs, and the MICs did not change after therapy.
我们对从35名社区获得性肺炎儿童中分离出的49株肺炎衣原体进行了体外克拉霉素和红霉素药敏试验。这些儿童是比较这两种药物的一项治疗研究的一部分。克拉霉素的活性比红霉素高2至10倍,90%受试菌株的最低抑菌浓度(MIC)以及90%受试菌株的最低杀衣原体浓度为0.031微克/毫升,而红霉素为0.125微克/毫升。这些儿童中有8名治疗后培养仍呈阳性,其中2名接受红霉素治疗,6名接受克拉霉素治疗。我们对这些儿童的21株分离株进行了检测。所有分离株对两种药物均敏感,且治疗后MIC未发生变化。
