The relevance ofEscherichia coliassociated bacteriuria infection in pregnant women is poorly understood, despite these strains sharing a similar virulence profile with other extra intestinal pathogenicE. coliproducing severe obstetric and neonatal infections. We characterized and determined the antimicrobial susceptibility, resistant genes and virulence profiles of 82E. coliisolates associated with asymptomatic bacteriuria in some pregnant in five very distinct hospitals in the Volta region from January, 2016 to April, 2016 using Kirby-Bauer disc diffusion and polymerase chain reaction.High levels of antimicrobial resistance was observed to Ampicillin (79.3%), Tetracycline (70.7%) and Cotrimoxazole (59.8%), except for Cefuroxime (32.9%). Resistant genes analyses revealed 58.5% were positive forBlaTEMand 14.6% foraph(3)-Ia(aphA2). Virulence factors (VFs) was more widespread in pregnant women in the 2ndand 3rdtrimesters than 1sttrimester. VFs relating to adhesion (papC andiha), Protectins (traT), aerobactin acquisition (iutA) and iron acquisition systems (fyuA andirp2) were more prevalent in the resistantE. coliisolates. This study provides additional evidence for a link in bacteriuria and transmission of extra-intestinalE. coliin pregnant women to cause multi-resistant severe obstetric or neonatal infections. Considering the involvement of extra-intestinalE. coliin infections, our results may be helpful to develop strategies to prevent maternal and/ neonatal infections. In addition continuous surveillance is required to guide appropriate antibiotic usage in pregnant women.
