Antimicrobial resistance was characterized for 14 strains of Streptococcus mitis. HinfI restriction fragment length mapping of gyrA PCR amplicons from three ciprofloxacin-resistant isolates correlated with mutations associated with such resistance in other organisms. By using PCR, seven erythromycin-resistant strains were found to possess either the mef or ermB gene. Hybridization revealed tet(M) in seven tetracycline-resistant isolates.
对14株缓症链球菌的抗菌药物耐药性进行了表征。来自三株环丙沙星耐药分离株的gyrA PCR扩增子的HinfI限制性片段长度图谱与其他生物体中与这种耐药性相关的突变相关。通过PCR,发现七株红霉素耐药菌株携带mef或ermB基因。杂交显示七株四环素耐药分离株中有tet(M)。
