Antimicrobial resistance of human non-typhoidal Salmonella in Ankara, Turkey
Abstract number: 902_p773
In this study we aimed to investigate the antimicrobial resistance and the epidemiologic characteristics of 423 human non-typhoidal Salmonella spp. isolates which were obtained from stool specimens of 11 768 patients between 1996 and 2001.
Between 1996 and 2001, 423 Salmonella spp. isolates were obtained from the community acquired infections in Ankara, Turkey. Salmonella strains were identified by standard biochemical reactions and using spesific O and H antisera. Antimicrobial susceptibility for Ampicillin (AMP), trimethoprimsulfametoxazole (TMPSXT) and ciprofloxacin (CIP) was determined by the disk diffusion method according to National Committee for Clinical Laboratory Standards.
Species which were identified in this study were 293 (69.2%) S. enteritidis, 86 (20.3%), S. typhimurium and 44 (10.3%) others. In order to show the differences in epidemiology and antimicrobial resistance, the study was divided into two periods: 19961998 and 19992001. The isolation rates of S. enteritidis, S. typhimurium and the others were 74.2, 18.2 and 7.6%, respectively, in the first period. In the second period isolation rates were found 51.6, 29 and 18.4%, respectively. Antimicrobial resistance for (AMP and TMP-SXT) in S. enteritidis, S. typhimurium and others were found (33.0/11.6%), (31.6/16.6%) and (19.0/8.0%) in the first period and (41.0/17.0%), (42.3/19.2%) and (23.0/15.0%) in the second period, respectively. All the isolates were susceptible to ciprofloxacin except one in other non-typhoidal Salmonella group.
The increasing number of ampicillin and trimethoprimsulfametoxazole resistant Salmonella strains makes these drugs unsuitable for empiric treatment."
