Escherichia coli (E. coli) O157:H7 is a common cause of bloody diarrhea in developed countries. The aim of this study was to determine whether E. coli O157:H7 is a possible pathogen of bloody diarrhea in southern Iran. Out of 719 children with diarrhea, 243 (34%) patients with positive occult blood took part in our study. The polyclonal antibody test and polymerase chain reaction (PCR) were used to identify E. coli O157:H7. Stool cultures showed enteropathogens in 107 patients (44%). Shigella (34.3%) was followed by E. coli (8.6%), campylobacter (2%) and salmonella (0.4%). None of the E. coli species was of O157:H7 serotype. Antibiotic sensitivity of shigella species was 100% to ceftriaxone, ciprofloxacin and ceftazidime, 94% to nalidixic acid and 13% to co-trimoxazole. The results of the study showed that E. coli O157:H7 is not a cause of bloody diarrhea in our area.
大肠杆菌O157:H7是发达国家血性腹泻的常见病因。本研究的目的是确定大肠杆菌O157:H7是否为伊朗南部血性腹泻的可能病原体。在719名腹泻儿童中,243名(34%)潜血阳性患者参与了我们的研究。采用多克隆抗体检测和聚合酶链反应(PCR)来鉴定大肠杆菌O157:H7。粪便培养显示107名患者(44%)有肠道病原体。志贺菌(34.3%)之后是大肠杆菌(8.6%)、弯曲杆菌(2%)和沙门氏菌(0.4%)。所有大肠杆菌菌株均非O157:H7血清型。志贺菌属对头孢曲松、环丙沙星和头孢他啶的抗生素敏感性为100%,对萘啶酸的敏感性为94%,对复方新诺明的敏感性为13%。研究结果表明,大肠杆菌O157:H7不是我们地区血性腹泻的病因。
