Antibiotic Susceptibility of Vibrio cholerae Strains isolated in Makkah, Saudi Arabia

Abstract

The antimicrobial activity of 15 antibiotics against 73 Vibrio cholerae 01 strains ogawa type, El Tor biotype was determined using the disc diffusion method. Most of the isolates (91.8%) were resistant to trimethoprim/ sulphamethoxazole, 82.2% to streptomycin, 61.6% to furazolidone, 57.5% to tetracycline, 54.8% to rifampicin, 39.7% to erythromycin, and 27.4% to ampicillin. Less than or equal to 3% were resistant to gentamicin, chloramphenicol, and neomycin. All were sensitive to ciprofloxacin, ofloxacin, nalidixic acid, norfloxacin, and tobramycin.
