The emerging drug resistance, especially among the Escherichia coli (E.coli) isolates from pregnant women, spread rapidly within the community. Urinary tract infection (UTI) is a well-known bacterial infection posing serious health problem in pregnant women. Also, multi-drug resistance is becoming rampant, and it is of serious public health concern. Treatment of E. coli is now a challenge due to continuous increase in resistance towards commonly prescribed antibiotics, thus posing a threat to treatment. Hence, the aim of the study is to determine antibiotic resistance genes in some multiple antibiotic resistant E.coli from apparently healthy pregnant women in Osun State. A cross-sectional study design was used to collect 150 mid-stream urine samples from apparently healthy pregnant women from March, 2018 to September, 2018. A well structured questionnaire and informed consent were used for data collection. Standard loop technique was used to place 0.001 ml of urine on Cysteine Lactose Electrolyte Deficient (CLED) medium, Blood agar, MacConkey agar and incubated at 37 °C for 24 h. A standard agar disc diffusion method was used to determine antimicrobial susceptibility pattern of the isolates. The molecular detection of the resistant genes was done using PCR techniques. The ages of women enrolled in this study ranges from 22 to 42 years (mean ± standard deviation = 31 ± 4.7 years). Escherichia coli showed high percentage of resistance to ampicillin and low resistance to ciprofloxacin and penicillin. All the E. coli isolates were sensitive to levofloxacin, and most were resistant to Meropenem. Multiple drug resistance was observed in all the isolates. Resistance genes in VIM 390bp, bla ctx-M 585bp and TEM 517bp were detected in some of the representative E. coli isolates profiled. This study identified the presence of Multi-drug resistance genes in E. coli associated UTI among pregnant women in Osogbo.
