Abstract：
This study aimed to investigate the contamination of carcasses and slaughterhouse environment with Escherichia coli O157:H7 and non-O157 serogroups (O45:H2, O103:H2, O121:H19, O145:H28, O26:H11, O111:H8). For this purpose, a total of 150 samples (30 carcasses, 30 shredding units, 30 knives, 30 slaughterhouse waste water and 30 wall surfaces) were collected from 5 different slaughterhouses in Kayseri, Turkey. The conventional and molecular methods were performed in order to detect Escherichia coli and its serogroups. Of the 150 samples, 55 (36%) were found to be contaminated with E. coli. Among isolates, E. coli serogroup (O157:H7) were detected in 2 (11%) carcass and 2 (11%) wastewater samples. None of the E. coli isolates harbored tested genes (stx1, stx2, eaeA, and hylA). Effective infection control measures and antibiotic stewardship programs should be adopted to limit the spread of multidrug-resistant bacteria. It was also deduced that these isolates resistance to different antibiotics could be hazardous for public health.
摘要：
本研究旨在调查大肠杆菌O157：H7和非O157血清群（O45：H2，O103：H2，O121：H19，O145：H28，O26：H11，O111：H8）对屠体和屠宰场环境的污染。为此,共150个样本(30具尸体，30个切碎单位，30刀,30个屠宰场废水和30个墙面）是从开塞里的5个不同的屠宰场收集的，土耳其。进行常规和分子方法以检测大肠杆菌及其血清群。在150个样本中，发现55（36％）被大肠杆菌污染。在分离物中，在2（11％）car体和2（11％）废水样品中检测到大肠杆菌血清群（O157：H7）。没有大肠杆菌分离株含有测试基因(stx1、stx2、eaeA、和hyla）。应采取有效的感染控制措施和抗生素管理计划，以限制多药耐药菌的传播。还推断，这些分离株对不同抗生素的耐药性可能对公众健康有害。
