%X The results of the study of antibiotic resistance of Enterobacteriaceae isolated from water of the Volga River delta and the gills, liver, colon zander are presented. 355 representatives of zander and 300 samples of water are analyzed. As a result, there have been tested 1296 strains of Enterobacteriaceae isolated from water and fish. Antibiotic resistance of bacteria was determined by standard methods of agar disk diffusion with benzyl penicillin, ampicillin, cefazolin, erythromycin, furadonin, tetracycline, chloramphenicol and tobramycin. Strains resistant to four or more antibiotics are considered to be polyresistant. Comparative data on their sensitivity to the test antibiotics are given. It is stated that all the studied organisms have multiple antibiotic resistance, depending on the season and habitable biotope. Water strains of Enterobacteriaceae of Belinsky and the main bank were resistant to the used antibiotics in 57.6 ¡À 0.4 and 45.4 ¡À 0.8 % of cases, respectively. Significant differences in the strains isolated from fish in these areas have not been established. Average minimum sensitivity of water strains to benzyl penicillin was 3.9 ¡À 0.9; fish strains ¨C 3.6 ¡À 0.7 % of samples. Average maximum sensitivity of aquatic strains to chloramphenicol and tobramycin was 8.2 ¡À 1.0 and 11.2 ¡À 0.9 % of samples, respectively. A similar sensitivity of fish strains to chloramphenicol and tobramycin was 8.4 ¡À 0.9 and 10.6 ¡À 0.8 % of samples. Minimum antibiotic resistance of Enterobacteriaceae was registered to tobramycin and chloramphenicol in water and gills, the maximum to benzyl penicillin and ampicillin in the intestines of fish. The obtained data can be used as markers of sanitary-epidemiological and ecological problems of freshwater hydro-ecosystem.
