The purpose of the study – to determine antimicrobial susceptibility of Shigella spp. and Salmonella spp. isolated in Ekaterinburg during June–September 1999. Susceptibility to ampicillin, ampicillin/sulbactam, ciprofloxacin, norfloxacin, tetracycline, cefotaxime, ceftriaxone and co-trimoxazole was tested by microbiological analisator «Sceptor» (Becton Dickinson, USA). Among tested microorganisms the most resistant was S. flexneri – 98,1% of strains were resistant to ampicillin, 49,1% – to ampicillin/sulbactam, 87,8% – to tetracycline, 73,6 – to co-trimoxazole. Among S. sonnei high rates of resistance to tetracycline (64,1%) and co-trimoxazole (97,6%) were detected. Most of strains of Salmonella spp. were sensitive to tested antimicrobials. The most active among tested antimicrobials were fluoroquinolones (ciprofloxacin and norfloxacin) to which all tested strains were sensitive, and cephalosporines III (cefotaxime and ceftriaxone) – 98,5% of Salmonella spp. strains and 100% Shigella spp. strains were sensitive.
