Özet
The present study included 223 E. coli strains isolated from homemade white cheeses and was undertaken to determine the prevalence of extended spectrum beta-lactamases (ESBL)-producing strains and antibiotic susceptibility. ESBL production was detected using three methods: the NCCLS disk diffusion test, the double disk synergy test and the NCCLS confirmatory test. By the disk diffusion test, 48% isolates were determined as potential ESBL producers. ESBL production by the double disk test and the phenotypic confirmatory test was found to be 16.1 and 9.9%, respectively. Susceptibility of all isolates against 16 antimicrobials was tested by the disk diffusion method. All strains were imipenem- and cefepime-susceptible. Susceptibility of E. coli to ceftazidime, ceftriaxon, cefotaxime and aztreonam was found to be 93.7, 96.4, 81.2, 90.6%, respectively. The least effective antibiotics were ampicillin with a rate of 68.6% and cefuroxime with a rate of 69.1%.
