Summary. Salmonellosis is recorded in all regions of the world. Salmonella bacteria are widely common among domestic and wild animals. Salmonellosis is registered as group and sporadic outbreaks. The greatest danger is posed by epidemiological animal-bacillicarriers due to lack of any signs of disease. 2 384 cultures of Salmonella of 24 serological variants were identified from farm animals and birds in 2012. Most often they were revealed in Penza (106), Moscow (64) Perm (56) and Tula (50) regions. 1 659 Salmonella strains were identified from fodders. According to the authors the highest number of cases were annually identified in poultry, horned cattle and pigs. It is proved that the greatest number of positive results were registered in birds (54%), cattle (18%) and pigs (18%). Most frequently following serological variants of Salmonella were allocated in animals in 2012: S. enteritidis (35,96%), S. typhimurium (13,7%), S. Dublin (11,19%), S. cholerae suis (10, 13%), S. gallinarum pullorum (8%). Causative agent of salmonellosis was detected in 2012 in products of animal origin in 804 cases, the largest number of which were identified in poultry (352), pork (217) and beef (105). In general, high resistance of Salmonella cultures to antimicrobial preparations used in testing is revealed (resistance was 40% or more). Authors studied etiological structure and distribution of Salmonella in animals. High resistance of Salmonella pathogens to preparations of penicillin group, cephalosporins and fluoroquinolones, polymyxin, erythromycin, chloramphenicol, tetracycline was established by the authors.
