Özet
The aim of this study was to isolate thermophilic Campylobacter species from broiler carcasses and feces and to determine the antimicrobial resis- tance and virulence genes of the isolates. The isolation rates of thermop- hilic Campylobacter species in cloacal swab and carcass/meat samples were 16% and 43.33%, respectively. The presence of virulence genes such as dnaJ, racR, ciaB, pldA, cadF, and virB11 in cloacal isolates were determined as 82.22%, 20%, 13.33%, 17.77%, 20%, and 0%, respectively. The rates of the same genes in isolates obtained from chicken meats were 62.07%, 34.48%, 27.59%, 27.59%, 17.24%, and 0%, respectively. The rates of tet(O), blaOXA-61, aphA-3–1, and cmeB genes in cloacal isolates were 22.22%, 0%, 17.78%, and 37.78%, respectively, while the rates of the same genes in isolates obtained from chicken meats were 10.35%, 0%, 3.45%, and 34.48%, respectively. As a result of enterobacterial repeti- tive intergenic consensus-polymerase chain reaction (ERIC-PCR) analysis, based on a 70% similarity rate, eight unique types and two clusters in chicken meat and carcass isolates and one unique type and four clus- ters in cloacal isolates were determined. The data obtained in this study demonstrated that thermophilic Campylobacter species represent a sig- nificant public health concern due to their high prevalence and antibiotic resistance, particularly in carcass and meat samples intended for human consumption.
