Plasmid-mediated antibiotic resistance and colicinogeny among Salmonellae in Rio de Janeiro, Brazil. 1984

S A Vinhas, and D F De Almeida

A set of 25 multiple drug-resistant strains selected from Salmonellae isolated from sewage in Rio de Janeiro contained S. typhimurium (60%) and S. agona (20%) as the most frequent serotypes. There was resistance to ampicillin (Ap), 92%; chloramphenicol (Cm), 76%; gentamicin (Gm), 84%; kanamycin (Km), 84%; streptomycin (Sm), 96%; tetracycline (Tc), 76%; trimethoprim-sulfamethoxazole (SuTp), 84% and nalidixic acid (Na), 52%. The most frequent resistance patterns observed were Ap Cm Gm Km Sm Tc SuTp Na and Ap Cm Gm Km Sm Tc SuTp. Two strains, bearing the streptomycin, tetracycline double-resistance pattern were colicinogenic, producing type Ib colicin. The col+ character was cotransferable with the double-resistance; all these markers were associated with the presence of a single 60 Mdal plasmid.

D012475 Salmonella A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that utilizes citrate as a sole carbon source. It is pathogenic for humans, causing enteric fevers, gastroenteritis, and bacteremia. Food poisoning is the most common clinical manifestation. Organisms within this genus are separated on the basis of antigenic characteristics, sugar fermentation patterns, and bacteriophage susceptibility.
