| Research Abstract |
Fluoroquinolone(FQ) resistance among Enterobacteriaceae species has been reported increasingly. It occurs primarily through mutation in the Quinolone Resistance-Determining Region(QRDR) of the DNA gyrase(gyrA) and topoisomerase IV(parC). I designed the mismatch PCR-RFLP to detect common mutations in QRDR of gyrA and parC. Developed mismatch PCR-RFLP successfully detected the mutations of gyrA and parC genes of Enterobacteriaceae clinical isolates with reduced susceptibility to FQs. This method offers an inexpensive, rapid, and easier alternative for detection of point mutations in FQ resistance in Enterobacteriaceae.
