Abstract

Background: Urinary tract infection (UTI) is one of the common bacterial infections. Escherichia coli is the most common cause of UTI. In this research, the prevalence of several virulence factors and beta-lactam resistance genes was investigated.

Methods: One hundred E. coli isolates were collected from patients' specimens with UTI referred to Allame-Bohlol Gonabadi hospital. Polymerase chain reaction (PCR) was performed to identify five pathogenic genes (fimH, aer, pap, hly, traT) and three antibiotic resistance genes (blaTEM, blaCTX, blaSHV).

Results: The frequencies of blaSHV, blaTEM and blaCTX beta-lactamase genes among extended-spectrum-beta-lactamases (ESBLs) positive isolates were 11.1%, 48.1%, and 93.3%, respectively. A significant number of isolates were resistant to the most commonly used antibiotics.

Conclusion: Pathogenic genes may also increase the severity, progression, and expansion of urinary tract infections. Therefore, identifying these genes as critical controllers of illness can use for better manage the treatment.

伊朗戈纳巴德医院转诊患者中大肠埃希菌致病基因（traT、hly、aer、pap 和 fimH）和抗生素耐药基因（blaTEM、blaSHV 和 blaCTX）的鉴定与评估。

背景：尿路感染（UTI）是常见的细菌感染之一。大肠埃希菌是导致尿路感染的最常见原因。本研究调查了几种毒力因子和β-内酰胺耐药基因的流行情况：方法：从转诊至 Allame-Bohlol Gonabadi 医院的UTI 患者标本中收集了 100 份大肠杆菌分离物。聚合酶链反应（PCR）鉴定了五个致病基因（fimH、aer、pap、hly、traT）和三个抗生素耐药基因（blaTEM、blaCTX、blaSHV）：结果：在扩谱β-内酰胺酶（ESBLs）阳性分离物中，blaSHV、blaTEM和blaCTXβ-内酰胺酶基因的频率分别为11.1%、48.1%和93.3%。大量分离菌株对最常用的抗生素具有耐药性：结论：致病基因也可能增加尿路感染的严重性、恶化和扩大。结论：致病基因也可能会增加尿路感染的严重程度、恶化和扩大，因此，确定这些基因是疾病的关键控制因子，可以更好地进行治疗。
