Introduction: Urinary tract infection is one of the major causes of consultation, microbiologic exploration, intensive use of antibiotics worldwide, and the second leading cause of clinical consultation in community practice. Many bacteria play a role in the urinary tract infections etiology, including Enterobacteriaceae such as Escherichia coli (E. coli) and Klebsiella spp.
Objective: The study’s main objective was to examine the epidemiology of E. coli and Klebsiella pneumoniae (K. pneumoniae) uropathogenic strains resistant to antibiotics in Franceville.
Methodology: The study was carried out between January 2018 and June 2019 in Franceville South-East Gabon. We examined a total of 1086 cytobacteriological urine samples. The identification of E. coli and K. pneumoniae strains was carried out using the Vitek-2 compact automated system and the antibiogram with the disk diffusion method according to the European Committee on Antimicrobial Susceptibility Testing recommendations.
Results: The prevalence of urinary tract infections was 29.2% (317/1086), of which 25.1% and 4.1% were mono-infections and co-infections, respectively. The prevalence of UTIs with E. coli was 28.7% (91/317) with a predominance of isolation in women. K. pneumoniae was responsible for 16.2% (61/317) of UTIs. E. coli and K. pneumoniae Uropathogenic strains showed resistance to beta-lactams, quinolones and cotrimoxazole, whereas Nitrofurantoin, Amikacin, Imipenem and Ertapenem were the most active antibiotics against E. coli and K. pneumoniae uropathogenic strains.
Conclusion: This study showed a high prevalence of urinary tract infections with a major implication of E.coli and K. pneumoniae strains. E. coli and K. pneumoniae presented high frequency of resistance to antibiotics, highlighting the need to adapt their use accordingly at the local level.
