The article describes the colonies of Salmonella spp. Some nutrient mediums were used for the in-vestigation. These were XLD, Endo, Levin, Ploskirev's agar and bismuth-sulfite agar. Laborato-ry researches were carried out in Perm region dur-ing 2015. Salmonella Typhimutium, S. Enteritidis, S. Gallinarum-Pullorum, S. Dublin, S. Cholerae-suis, S. Infantis, S. Hamburg, S. Virchow (24 strains) were worked out. The innovative develop-ment medium was used for not selective enrich-ment of salmonellas. For control buffering peptonny water was used. After incubation during the 18-24 hours at 37 °C doing subcultivation on agar medi-ums and in 24 and 48 hours studied nature of growth of microorganisms. As a result of both tests, and control samples of Salmonella spp. typical col-onies on agar nutrient mediums were formed. Es-sential difference between control and prototypes samples was time of generation colonies. Faster formation of colonies in prototypes in comparison with control was recorded. The salmonellas en-riched in the innovative method on some agar nu-trient mediums in 24±2 hours of incubation gave growth typical colonies in a form and color. Salmo-nella bacteria enriched by a standard way needed more time for generation colonies and the quantity of colonies was smaller on 12.5-37.5% than in ex-perience.
