Study’s Novelty/Excerpt
- This study assesses the prevalence and antibiotic resistance patterns of diarrheagenic Escherichia coli (DEC) in children under five in Sokoto, revealing a significant 21% prevalence rate with alarming multidrug resistance (MDR) profiles.
- By identifying the presence of class 1 integrons in these MDR isolates, the research reveal the escalating public health risk posed by antibiotic-resistant DEC.
- These findings highlight the urgent need for antibiotic stewardship programs and targeted infection control strategies to mitigate the spread of resistant strains in vulnerable populations.
Full Abstract
Diarrheal diseases continue to pose substantial public health challenges, especially in children under the age of 5. Diarrheagenic Escherichia coli (DEC) is the second most common cause of diarrhea in children after Rotavirus. This study aimed to assess the prevalence of antibiotics resistant DEC recovered from diarrheic children 0-5 years in Sokoto. Stool samples were obtained from 300 diarrheic kids attending two hospitals in Sokoto. Bacterial isolates that showed colonial morphology suggestive of E. coli were subjected to antibiotic susceptibility testing. PCR was carried out to confirm the presence of DEC and resistant genes among the multiple antibiotic-resistant isolates. Structured questionnaires were administered to determine the risk factors that predispose the children to diarrhea. The result revealed a 21% prevalence of E. coli isolates, out of which 75% displayed resistance to Ampicillin, 75% to Nalidixic acid, 30% to Gentamycin, 23% to Ofloxacin, 74% to Cefotaxime, 23% to Ceftriaxone, 18% to Nitrofurantoin, 10% to Imipenem and 73% to Cefuroxime. Out of the 30 E. coli isolates with a MAR index of ≥ 0.2, 12 were found to be multidrug-resistant (MDR). All four MDR E. coli selected were confirmed to be DEC using the UidA gene. Out of all the four MDR DEC confirmed, only one class 1 integron was detected. Raising concern about misuse of commonly used antibiotics. This study highlights the need for implementing antibiotic stewardship programs and infection control measures to combat the growing threat of antibiotic-resistant DEC within Sokoto.
