Salmonella Typhi mutants in glnA gene show susceptibility to ciprofloxacin. A disk diffusion assay was performed to measure inhibition zones of S. Typhi STH2370 (WT), S. Typhi STH2370 glnA::EZ-Tn5, S. Typhi STH2370 glnA::kan and S. Typhi STH2370 glnA::FRT. The strains were seeded onto MH agar plates pH 7.3. Followed, 5 μL of ciprofloxacin 2 mg/mL were spotted onto a filter paper disk and placed on the plates and incubated at 37°C for 16–18 h.
