This study aimed to evaluate 50 different cheese samples in terms of certain microbiological parameters. The presence of Salmonella spp. and Listeria spp. in cheeses were investigated by immunomagnetic separation and conventional methods. Staphylococcus aureus was detected in 4 samples, while 2 samples were accepted suspicious of Salmonella spp. and 5/50 samples were found positive with respect to Listeria spp. The suspicious Salmonella spp. isolates were determined as Proteus mirabilis. Therefore, Salmonella spp. were not determined from the samples. The isolates of Listeria spp. were identified as Listeria monocytogenes (2/5), Listeria grayi (3/5). According to antibiotic test results, Staphylococcus aureus isolates showed susceptibility to tetracycline, trimethoprim, gentamicin, chloramphenicol, sulphamethoxazole/trimethoprim, ciprofloxacin at the level of 100%. Additionally, the Listeria spp. isolates displayed high susceptibility to chloramphenicol, ciprofloxacin, and ampicillin.
