Materials and Methods:A total of 346 samples of different clinical strains of enterobacteriaceae were isolated from Kahooresten. To determine the resistance of the samples, an antibiotic test was performed. Finally, ESBL isolates were tested by PCR for TEM, CTX-M, and SHV genes. Results:Of the 346 isolates studied, 162 isolates of Klebsiella and 132 isolates of Escherichia coli were resistant to ceftazidime antibotic or cefotaxime, or both. Also, 82 (42.26%) were isolates producing ESBL. Conclusions:Due to the high percentage of resistance to third-generation cephalosporins, accurate antibiotic testing before antibiotics is required in infections caused by ESBL-producing organisms. %> http://ncmbjpiau.ir/article-1-1075-en.pdf %P 9-16 %& 9 %! %9 Research Article %L A-10-966-3 %+ Department of Microbiology, Islamic Azad University Jahrom, Jahrom, Iran %G eng %@ 2228-5458 %[ 2018
