Salmonellosis is unmatched in its epidemiological complexity and difficulty in controlling it. The biology of salmonella serovars varies so widely that it inevitably makes it difficult to discuss issues related to salmonellosis, the ways and mechanisms of infection with Salmonella and contamination with Salmonella. At the end of the 20th century, a significant contribution to the spread of multiple resistance in many countries was made by the epidemic spread of multidrug-resistant strains of S.
Typhimurium 104, which caused diseases in humans and were isolated from animals. We examined 31 samples from carcasses of broiler chickens and 40 strains of Salmonella isolated from patients with acute intestinal infections, hospitalized in the clinic NIIEMIZ MH RUz. Having carried out genotyping of Salmonella spp strains isolated from patients with AEI and from carcasses of broiler chickens, we see a variety of resistance genes, however, the resistance genotypes isolated from the carcasses of broiler chickens bla NDM-1, CTX-M, -TEM, -SHV, which amounted to 6.5 %. These strains carry a gene resistant to antibiotics belonging to the reserve group - carbopenems (imipenem).
