Antibiotic susceptibility of salmonella strains isolated from faeces
Özet
During the six months period, from August 1992 to January 1993, forty-six Salmonella strains isolated from faeces, were identified by Slide Agglutination Test using Salmonella Antisera (BBL). Susceptibilities of Salmonella strains to antibiotics were also determined via the Disk Diffusion Technique of Kirby-Bauer. Forty-five of forty-six strains were defined as group B Salmonella while one of forty-six was determined to be group D. Results of antibiotic susceptibility test were as follows: Group B strains 100% resistant to Ampicillin, Mezlosilin, Piperasilin, and Chloramphenicol, 97.8% to Cefazoline, 82.2% to Sefotaksim, 75.6% to Ampicillin-Sulbactam and Tobramisin, 73.3% to Ceftriaxone, 66.7% Aztreonam, 20.0% to Trimethoprim-Sulfamethoxazole, 8.8% to Gentamisine and 6.7% to Amikasin. Nevertheless, we observed no resistance against Imipenem and Siprofloksasin. The strain of group D Salmonella was susceptible to all antibiotics tested. In conclusion, a high degree of resistance against first choice antibiotics such as Ampicillin, Chloramphenicol and third generation Cephalosporins was established. Therefore the regional antibiotic resistance should be considered for the treatment of Salmonella infections.
