Popis: The emergence and spread of Carbapenem-Resistant Enterobacterales (CRE) has become a growing concern for health services, internationally, nationally, and regionally. In Morocco, the situation is more worrisome as studies on CRE are scarce and/or scattered and/or outdated. As a result, we carried out the present study to determine and update CRE prevalence at Mohammed VI University Hospital of Marrakech, Morocco.A cross-sectional prospective study was carried out from March 2018 to March 2020 on 41161 clinical specimens of 23,469 patients suspected of bacterial infections. Enterobacterales strains were isolated following standard bacteriological procedures. Bacterial strains were identified using BD-Phoenix and MALDI-TOF-MS. Antibiotic susceptibility was determined for 14 antibiotics. Carbapenemase production and phenotypic detection were characterized using modified carbapenem inactivation phenotypic and immunochromatographic methods.All in all, 484 Enterobaterales resistant to at least one carbapenem were recovered. The majority was isolated from the neonatal unit (14%), followed by the urology-nephrology (11%), and plastic surgery departments (10%). K. pneumoniae (n=232) was the most isolated, followed by E. cloacae (n=148), E. coli (n=56), and S. marcescens (n=17). Antibiotic susceptibility profile showed high rates of resistance to ciprofloxacin (75.21%), gentamicin (84.50%), and cotrimoxazole (88.42%). Out of 484 CRE positive cultures, 388 (80.16%) were Carbapenemase-positive. Out of the latter, 170 were metallo-beta-lactamase producers (NDM), 162 OXA-48-like, and 56 both.These findings emphasize the urgent need for control precautions and strict measures to contain and mitigate this issue.
