gyrA ser83 mutation among fluoroquinolone-resistant Salmonella enterica serovars from enteric fever patients in tertiary care hospital, Kathmandu

Table 4 Distribution of gyrA restriction pattern based on the fluoroquinolone resistance pattern (n = 32)

Fluoroquinolone resistance phenotypes	NAR/NAS	No. of *Salmonella* spp (%)	MIC value for Ciprofloxacin (μg/ml)	*gyrA* ser83 mutation
CIP_R	NAR	9 (28.1)	0.5–16	Mutated (+)
CIP_I	NAR	20 (62.5)	0.12–2	Mutated (+)
CIP_I	NAS	3 (9.4)	0.06	Non-mutated (−)

Note CIP_R = Ciprofloxacin resistant, CIP_I = Ciprofloxacin intermediate, NAR = Nalidixic Acid Resistant, NAS = Nalidixic Acid Sensitive
