Prevalence of resistant Escherichia coli strain isolated from community acquired urinary infection in university hospital HASSAN II of Fez, Morocco

Abstract
Abstract: The urinary tract infection is one of the most common infections acquired in community and hospital. The emergence of the acquired resistance of bacteria to antibiotics remains an important issue relevant to antimicrobial strategies. The Purpose of this paper is to review the frequency of isolation and the evolution of the resistance to antibiotics of the tree strains of Escherichia coli causing community urinary tract infections. It is a retrospective study made in the laboratory of microbiology of the university hospital center HASSAN II of Fez, concerning germs isolated from 5287 positive Bacteriological examination of urine (BEU) collected between 2010 and 2016 and diagnosed in consulting externs. Enterobacteriaceae were responsible for 84 % of the community urinary tract infections. The women were more touched (sex ratio F/H = 1, 66). Escherichia coli dominated the epidemiological profile (62 %). The antibiotic resistance of the tree strains of E. coli isolated highlighted rates of resistance to amoxicillin (64 %), to ciprofloxacine (59 %), to association amoxicillin-acid clavulonic (46 %), to sulfamethoxazole-triméthropime (42 %), to gentamicine (25 %), and to amikacine (14 %). The number of tree strains of E.coli resistant to third generation cephalosporins by production of B-lactamases with widened spectre"ESBL -producing" was 258, that is an average frequency of 5.8 % of all the enterobacteriaceae isolated. No resistance to imipeneme was registered for the tree strains of E. coli isolated whitch means that the sensibility to imipeneme is of 100 %. All these results showed an increase of the multiresistance of Escherichia coli in community environment which could be due to the excessive use of antibiotics in the medical domain. A regular surveillance of the resistance to antibiotics is essential to define effective and appropriate therapeutic strategies, limiting the emergence and the scattering of the multiresistant tree strains. Keywords: urinary tract infection - Escherichia coli - Antibiotics – surveillance.
