摘要

Healthcare-associated infections (HCAIs) remain a major public health concern. The aim of this study was to characterize potential pathogenic bacteria isolated in high-risk infectious services at the University Hospital Center of Suru-Léré in Benin. A cross-sectional, descriptive study was carried out on 215 samples with 8 air samples, 20 hand samples and 187 samples of medical-technical material. Genes for resistance to <i>β</i>-lactam antibiotics (blaTEM, blaSHV, blaCTX-M and blaOXA-1) were sought. The data were processed and analyzed using EPI Info version 3.5.4 software. A total of 10 bacterial species were identified. Of the 319 bacterial strains identified, <i>Staphylococcus saprophyticus</i>, <i>Staphylococcus aureus</i> and <i>Enterococcus faecalis</i> were predominant at 20.06%, 17.87% and 11.28% respectively. Antibiotic susceptibility showed that the majority of bacterial strains were multidrug-resistant. Of the 4 resistance genes sought, only the blaTEM and blaSHV genes were found. The poor microbiological quality observed in high-risk infectious services could be a risk factor for healthcare-associated infections. It is therefore useful to implement preventive measures in order to prevent or reduce the risk of healthcare-associated infections.
