Evidence
|
However, NAr mutations found in 6 isolates (37.5%) involved 7 positions including rtL91I, rtT128I, rtQ215P, rtF221Y, rtN238D, rtC256S, and rtI266G. Substitutions at 3 NAr mutation sites (rtT128I, rtN238D, and rtC256S) were detected in 3 unresponsive patients developing drug resistance after NA treatment.
