BACTERIAL PROFILE, ANTIMICROBIAL RESISTANCE, AND FACTORS ASSOCIATED WITH URINARY TRACT INFECTION AMONG PREGNANT WOMEN...

Urinary tract infection in pregnancy is a common microbial infection. Antimicrobial resistance among uropathogens is becoming a major health problem worldwide. The antimicrobial agents used to manage urinary tract infections during pregnancy should be carefully chosen. Therefore, this study aimed to determine the bacterial profile, antibiotic susceptibility pattern, and factors associated with urinary tract infection among pregnant women at Hosanna town public health facilities. A facility-based cross-sectional study was conducted from March to August 2022 on a total of 312 pregnant women who attended antenatal care at Hosanna Town public health facilities. Sociodemographic, clinical data, and related information were collected by using a pre-tested questionnaire. In addition, mid-stream urine specimens were collected from study participants. Bacterial pathogens were identified by standard bacteriological techniques. Antibiotic susceptibility testing was performed by using the Kirby Bauer disk diffusion method. The data were analyzed by using SPSS version 25. Chi-square and odds ratios were calculated and a P-value≤0.05 at a 95% confidence interval was considered statistically significant. The results were presented with words and tables. Of a total of pregnant women, 59/312(18.9%) (95% CI: 14.7-23.7) were found to have significant bacteriuria. The predominant isolates were Escherichia coli (E. coli) 22(34.4%), followed by coagulase-negative staphylococci (CoNS) 10(15.6%), Staphylococci aureus (S. aureus) 7(10.9%), and Klebsiella pneumoniae (K. pneumoniae) 6(9.4%). Overall, 78.1% of these isolates were multidrug-resistant (MDR). Gram-negative bacteria were susceptible to meropenem (97.6%), gentamicin (85.7%), nitrofurantoin (82.1%), ciprofloxacin (73.8%), amoxicillin-clavulanic acid (73.8%) and ceftriaxone (71.8%), but highly resistant to ampicillin (95.5%), trimethoprim-sulfamethoxazole (74.4%), doxycycline (71.8%), cefuroxime (69.2%), and cephalexin (69.2%). The gram-positive bacteria were susceptible to gentamicin (86.4%), erythromycin (81.8%), and nitrofurantoin (77.3%): whereas they showed a high level of resistance to penicillin (72.7%), doxycycline (54.5%), trimethoprim-sulfamethoxazole (52.9%), and cefoxitin (52.9%). No formal education for the participant (AOR: 2.86, 95% CI: 1.03-7.98, p=0.044), family monthly income <1500 birr (AOR: 3.19, 95% CI: 1.48-6.89, p=0.003), and previous history of UTI (AOR: 4.52, 95% CI: 2.04-10.03, p=0.001) were significantly associated with bacteriuria. This study revealed a high prevalence of bacterial urinary tract infection among pregnant women and low susceptibility to ampicillin, trimethoprim-sulfamethoxazole, cefuroxime, and cephalexin. Therefore, regularly, culture-based bacterial identification and antibiotic susceptibility testing should be performed. Alternatively, empiric antibiotic therapy should consider the prevalence of antibiotic-resistant uropathogens and the factor that may increase the urinary tract infection occurrence due to multi-drug resistant uropathogens.
