The purpose of the current work is to learn more about Yersinia spp. Isolated from chicken meat products. A total of 100 samples were obtained from various retail markets at Tanta, Gharbia governate, Egypt. Represented by chicken burger, Pane, luncheon, and nuggets (25 of each). Yersinia spp. was isolated from chicken burger, Pane, luncheon, and nuggets at 8%, 32%, 8%, and 16% respectively . Antimicrobial tolerance has been studied by using the disk dispersion methods, Yersinia isolates' levels of resistance were assessed to the seven various antimicrobial drugs. Sixteen isolates indicated resistance to vancomycine (43.75%), gentamycin, and cefotaxime, respectively, as well as doxycycline (93.75), amoxicillin-clavulanic acid (62.5), ciprofloxacin (50%) and erythromycin (50%) in that order. Detection of Yersinia strains was successfully performed with traditional and recent methods (PCR technique) to investigate these genes 16S rRNA, ystA, ystB . The discovery of Yersinia spp. in products containing chicken meat showed that the need for more knowledge about the danger connected with the transportation and preparation of chicken .
