Uropathogenic (UPEC) harbors virulence factors responsible for bacterial adhesion and invasion. In addition, the bacterium is accountable for the occurrence of pediatric urinary tract infections globally and is becoming problematic due to the emergence of antimicrobial resistance. The current research investigated UPEC prevalence, virulence characteristics, and antimicrobial resistance in pediatric urinary tract infection (UTI). 200 urine specimens were taken from hospitalized pediatric patients who suffered from UTIs. was recovered from urine specimens using the microbial culture. Disc diffusion method was used to assess antimicrobial resistance and polymerase chain reaction (PCR) to assess the virulence factors distribution amongst the UPEC bacteria. Seventy-five out of 250 (30.00%) urine samples were positive for the UPEC bacteria. The UPEC prevalence amongst pediatric patients was 25.83% and 33.84%, respectively. UPEC bacteria harbored the maximum resistance toward gentamicin (45.33%), ampicillin (44.00%), and ciprofloxacin (40.00%). Cytotoxic necrotizing factor 1 ( (53.33%) and pyelonephritis-associated pil ( (42.66%) were the most frequently identified virulence factors amongst the UPEC bacteria. The high prevalence of UPEC isolates harboring antimicrobial resistance and virulence factors suggest that diseases caused by them need more expansive healthcare monitoring with essential demand for novel antimicrobials.
尿路致病性大肠杆菌(UPEC)携带的毒力因子与细菌黏附和侵袭有关。此外,这种细菌是导致全球儿童尿路感染的罪魁祸首,并且由于抗菌药物耐药性的出现,问题变得更加严重。本研究调查了儿童尿路感染(UTI)中 UPEC 的流行率、毒力特征和抗菌药物耐药性。从患有 UTI 的住院儿科患者中采集了 200 份尿液标本。使用微生物培养从尿液标本中分离出 UPEC。采用纸片扩散法评估抗菌药物耐药性,聚合酶链反应(PCR)评估 UPEC 细菌毒力因子分布。250 份尿液样本中有 75 份(30.00%)为 UPEC 阳性。儿科患者中 UPEC 的流行率分别为 25.83%和 33.84%。UPEC 细菌对庆大霉素(45.33%)、氨苄西林(44.00%)和环丙沙星(40.00%)的耐药性最高。细胞毒性坏死因子 1((53.33%)和肾盂肾炎相关菌毛((42.66%)是 UPEC 细菌中最常鉴定到的毒力因子。携带抗菌药物耐药性和毒力因子的 UPEC 分离株的高流行率表明,由它们引起的疾病需要更广泛的医疗保健监测,并迫切需要新型抗菌药物。
