The aim of our researches was to determine the properties of 17 Campylobacter jejuni strains that were isolated from poultry products. Methods. Isolation and identification of Campylobacter sp. we carried out by methods that are regulated by ISO 10272-1: 2007 with using biochemical markers: catalase and oxidase activity, the ability to hydrolyze of sodium hippurate. Pathogenicity of isolated cultures of Campylobacter sp. was examined on rabbits, chickens- hens of brown and white Hajseks cross, mice. Sensitivity to antibiotics was determined by disk diffusion method. Sensitivity to disinfectants was determined by method of successive serial dilutions at liquid nutrient medium. Results. The investigated bacteria were assigned to genus Campylobacter according to their morphological and culture features, ability to produce catalase and oxidase, and according to other signs. The isolates were highly sensitive to erythromycin and tylosin, they were resistant to trimethoprim, rifampicin and cephalexin. Bactericidal concentrations of disinfectants relative to C. jejuni were determined: "Bi-Des" - at 0.1%, "Brovadez-plus" - 1: 10000, formaldehyde and 1.5% "VetOks 1000" - 20%. Strains of C. jejuni were pathogenic for chickens, rabbits and white mice: LD50 of isolates - 2,0x108,72 cells/cm³. Conclusion. Isolation of 17th strains of Campylobacter jejuni from poultry products was proved. The isolates were pathogenic for chickens, and lab. animals. [ABSTRACT FROM AUTHOR]
