Abstract:
The purpose of this study was the determination of antiseptic resistance genes (qacA/B and qacC) from staphylococcal mastitis in cattle in various regions of Turkey. In total, 283 isolates (Burdur: 36, Hatay: 47 and Van: 200) were studied, and the antiseptic resistance genes were detected using simplex PCR. The distribution of the qacA/B and qacC genes, mediating resistance against quaternary ammonium compounds, was found to vary among the different isolates. The qacA/B genes were found in three of the Burdur isolates, six of the Hatay isolates and seven of the Van isolates. The qacC gene was found in two of the Burdur isolates, none of the Hatay isolates and two of the Van isolates. The presence of these genes and transmission among Staphylococcus spp. strains may pose risks in the control of mastitis, as well as to public health.
