Escherichia coli bacteriuria in pregnant women in Ghana: antibiotic resistance patterns and virulence factors
Abstract Objectives The relevance of Escherichia coli associated bacteriuria infection in pregnant women is poorly understood, despite these strains sharing a similar virulence profile with other pathogenic E. coli causing severe obstetric and neonatal infections. We characterized and determined the...

Results High levels of antimicrobial resistance were observed to ampicillin (79.3%), tetracycline (70.7%) and cotrimoxazole (59.8%), except for cefuroxime (32.9%). Resistance genes analyses revealed 58.5% were positive for Bla TEM and 7.3% for aph(3)-Ia(aphA2).

This study provides evidence for a link in bacteriuria and transmission of extra-intestinal E. coli in pregnant women to cause multi-resistant obstetric or neonatal infections. Considering the involvement of extra-intestinal E. coli in infections, results are helpful to develop strategies to prevent maternal and/ neonatal infections.http://link.springer.com/article/10.1186/s13104-018-3989-yEscherichia coliBacteriuriaPregnant womenGhana |
