The objective of this study was to determine the resistance phenotypes of bacteria isolated from nosocomial infections at the University Teaching Hospital of Point G. Urine, blood, pus, skin and bronchoalveolar fluid samples were taken in different units, and bacteria isolations were performed on usual selective media such as Drigalski Colombia agar supplemented with nalidixic acid and colistin and 5% sheep blood and chocolate agar. Identifications of bacteria such as <i>Enterobacteriaceae, Pseudomonas and acinetobacter, and</i> Staphylococci were done using API20<sup>E</sup> gallery, API20<sup>NE</sup> gallery and catalase/oxidase tests, and the Pastorex Staph kit respectively. The antimicrobial susceptibility testing was performed on Mueller-Hinton agar using the diffusion method. A total of 463 patients were inpatients for at least 48 h in the different units, and a nosocomial infection was notified in at least 57 patients (12.3%). A total of 65 episodes of nosocomial infections were observed in these 57 patients. Of the bacteria isolated, multidrug-resistant bacteria (MDR) represented 63.7% (n=36). These were extended-spectrum beta-lactamase (ESBL)-secreting <i>Enterobacteriaceae</i> (n=21), high-level cephalosporinase (n=13) and methicillin-resistant coagulase-negative Staphylococci (n=2). Despite this high number of multi-resistant bacteria isolated in this study; colistin and amikacin had very good activity on <i>enterobacteriaceae.</i> The results show the need to strengthen hygiene in the intensive care units in order to fight against nosocomial infections at the UTH of Point G.</p>","PeriodicalId":519908,"journal":{"name":"African journal of bacteriology research : JBR","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11089850/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140917656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
