Özet:

Extended spectrum beta lactams (GSBL) produced by gram-negative bacteria ensure that the bacteria is resistant to all penicillins, 1–4 generations sefalosporins and monobactams. In this study, the presence of E. coli carrier producing GSBL in Turkish Burdur islands and the presence of common GSBL genes in these isolates was studied. A 10% suspension was prepared in tamponed pepton water from each of the collected 150 pipe output samples and was planted simultaneously with E. coli / koliform selective agar foods prepared by the addition of sefotaxim and sefotaxim. The identification of E. coli from the colonies seen in their diet was done by standard methods and by genotypic verification with polymerase chain reaction (PZR). And then E. It was determined by the combined disc method where coli isolates produced GSBL or not and was studied by the common GSBL genes Sefotaksimaz-Münh (CTX-M), Temoneira (TEM) and sulfhidril variable (SHV) PZR. Finally, the sensitivity of insulates to various beta-lactam antibiotics and other classes of antibiotics was studied by the agar disk diffusion test. A total of 44 E. coli were isolated from selective agates, but 36 of them were identified as GSBL-producing isolates. CTX-M (Group 1) genes are identified in all isolates, while SHV genes are not found in any isolates. The E. coli isolates produced by GSBL were found to be highly resistant to beta-lactam group and other groups of antibiotics. As a result, with this study in Turkey’s Burdur province’s enterprises in healthy pests, GSBL is produced by E. The presence of coli and the prevalence of GSBL genes have been shown.
