The antimicrobial susceptibility of 15 of the 40 isolates examined showed that the strains were sensitive to tetracycline, ampicillin, furazolidone, erythromycin, and ciprofloxacin but resistant to trimethoprim-sulfamethoxazole, and also to the vibriostatic

agent 0/129, and ability to grow at 0% NaCl.
Its antibiotype showed resistance to trimethoprim-sulfamethoxazole, sulfonamides, trimethoprim, chloramphenicol, streptomycin, and vibriostatic agent O129 (a molecule naturally active against V.
cholerae isolated and 60 randomly selected tetracycline-susceptible strains were tested for sensitivity to the following drugs: ampicillin, cephalotin, doxycycline, sulfonamide, trimethoprim, trimethoprim-sulfamethoxazole, chloramphenicol, streptomycin, spectinomycin, neomycin, kanamycin, nalidixic acid, pefloxacin, erythromycin, rifampicin, and nitrofurantoin, as well as to vibriostatic agent 0129.
