Abstract

Of a total of 147 erythromycin-resistant Streptococcus pneumoniae isolates, 64 (43.5%) were resistant to erythromycin, clindamycin, and streptogramin B (MLSB phenotype), 57 of which possessed the ermB gene. Eighty-two (55.8%) were resistant to erythromycin alone (M phenotype), 81 of which possessed the mefE gene. One was erythromycin and streptogramin B resistant but susceptible to clindamycin (MS phenotype) and possessed neither the erm gene nor the mefE gene.

摘要

在总共147株对红霉素耐药的肺炎链球菌分离株中,64株(43.5%)对红霉素、克林霉素和链阳菌素B耐药(MLSB表型),其中57株携带ermB基因。82株(55.8%)仅对红霉素耐药(M表型),其中81株携带mefE基因。1株对红霉素和链阳菌素B耐药,但对克林霉素敏感(MS表型),既不携带erm基因也不携带mefE基因。
