Resistance to antibiotics and genotype characteristics of Salmonella enterica subspecies enterica serovar Mbandaka isolated from poultry

摘要

Salmonellas are one of the main zoonotic pathogens whose reservoirs are poultry, cattle and pigs. By means of the food chain salmonellas can be transferred to humans through contaminated food of animal origin. Multiresistant strains Salmonella are particularly dangerous since they can transfer genes of resistance to antibiotics to other microorganisms. Control of salmonellas primarily depends on a good surveillance system and knowledge of the strain types present in the epizootiologic area. In some geographical regions only a few Salmonella serotypes are usually of epidemiological importance. Due to the predomination of some serotypes and fagotypes, when an additional discrimination within serotypes and fagotypes is needed, DNA genotyping is used. In cases when it is necessary to compare the strains which caused the poisoning of patients, with strains isolated from food or animals, a highly discriminatory method is used - pulsed field gel electrophoresis (PFGE). Due to a high degree of discrimination the results of PFGE testing enable decision making with a higher degree of certainty in epizootiologic and epidemiologic research work. The aim of this testing was to determine the antibiotics resistance and genotype characteristics of Salmonella enterica subsp. enterica serovar Mbandaka isolated from poultry from some areas of the territory of Serbia.
