Activity of rifampin against 129 Streptococcus mitis isolates obtained from patients with hematologic cancer was investigated. One hundred twenty-five strains were susceptible to rifampin, and 4 were resistant (MIC = 32 to 64 microg/ml). Resistance to rifampin was related to mutations in the rpoB gene: His(526)Asn in three strains and His(526)Asp in one strain.
研究了利福平对129株从血液系统癌症患者中分离出的缓症链球菌的活性。125株菌株对利福平敏感,4株耐药(MIC = 32至64微克/毫升)。对利福平的耐药性与rpoB基因突变有关:三株菌株为His(526)Asn,一株菌株为His(526)Asp。
