The erm(41) gene causes inducible macrolide resistance in Mycobacterium abscessus but not Mycobacterium chelonae. erm(41) sequencing of 285 M. abscessus and 45 M. chelonae isolates was compared to 14-day susceptibility; agreement percentages were 98.9% and 100%, respectively. Extended incubation may not be necessary for M. chelonae, and the erm(41) genotype is a useful adjunct for M. abscessus.
erm(41)基因可导致脓肿分枝杆菌对大环内酯类药物产生诱导性耐药,但对龟分枝杆菌无此作用。对285株脓肿分枝杆菌和45株龟分枝杆菌分离株进行erm(41)基因测序,并与14天药敏结果进行比较;符合率分别为98.9%和100%。对于龟分枝杆菌可能无需延长培养时间,而erm(41)基因型对脓肿分枝杆菌是一种有用的辅助手段。
