چکیده

Background: The rising global emergence of Gram-negative bacteria (GNB) producing ?-lactam hydrolysing enzymes in clinical infections constitutes a growing public health threat. This study investigated the occurrence co-production extended spectrum ?-lactamase (ES?L), AmpC ?-lactamases, and carbapenemases among GNB isolated from HIVinfected patients two tertiary healthcare facilities southwest Nigeria.Methodology: A total 115 isolates previously recovered HIV-infected at Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, State Specialist Hospital, Akure, were investigated. characterized to species level with Microbact 24E kit screened for ES?L production using double-disc test (DDT) combination disc methods, modified Hodge (MHT) EDTA disc, carbapenemase MHT test. Antibiotic susceptibility testing (AST) was performed by Kirby-Bauer diffusion method.Results: 15 characterized. AST profile revealed high resistance rates ampicillin (94.5%), tetracycline (74.5%), sulphamethoxazole-trimethoprim (66.3%), lowest imipenem (10.9%). Multi-drug (MDR) observed 93.6% while 98.8% ES?L, AmpC, carbapenemase-producing had multiple antibiotic (MAR) indices ? 0.2. detected 53.9%, 20.9% 25.2% isolates. or all three 80 (69.6%) isolates, only 10.0% produced enzymes.Conclusion: isolation MDR co-producing immunocompromised individuals portend grave consequences. Routine screening these will be highly essential guide institution appropriate therapy infection control measures.

 Contexte: L'émergence mondiale croissante à Gram négatif produisant d'hydrolyse ?-lactame les cliniques constitue une menace pour la santé publique. Cette étude examiné l'occurrence coproduction ?-lactamases spectre étendu carbapénémases parmi isolés deux établissements tertiaires Nigéria.
 Méthodologie: Un isolats précédemment récupérés au complexe hospitalier universitaire Awolowo, ont été étudiés. Les caractérisés niveau espèces avec criblés d'ES?L en utilisant double disque méthodes disques combinés, modifié EDTA, EDTA. Le sensibilité aux antibiotiques effectué méthode Kirby-Bauer
 Résultats: caractérisées. profil révélé taux derésistance élevés l'ampicilline (94,5%), tétracycline (74,5%), sulfaméthoxazole-triméthoprime (66,3%) età plus faible résistance l'imipénème (10,9%). Une plusieurs médicaments observéedans 93,6% tandis que 98,8% producteurs avaient multiples 0,2. La détectée 53,9%, 20,9% 25,2% isolats. ou trois (69,6%), seulement 10,0% produit enzymes.
 Conclusion: L'isolement co-producteurs d'enzymes ?-lactamines chez individus immunodéprimés laisse présager graves conséquences. dépistage systématique ces sera très essentiel guider mise place d'une antibiothérapie appropriée mesures contrôle infections.

Efficacy of Amikacin and Imipenem Against Multi-Drug Resistant Gram-Negative Bacteria Isolated From Wound Infections

Background and Objective: Gram-negative pathogens are considered the common cause of wound infections associated with increased mortality and morbidity rates. Antibiotics combination has been used to overcome this problem. Aims: In this study, we identify Gram-negative pathogens found in wound infections and assess the in-vitro efficacy of a combination of amikacin and imipenem against the resi...

investigated of ampc in carbapenem resistant gram-negative bacteria isolated from burned patients

background : gram-negative bacteria are the most cause of nosocomial infection especially in burned patients. carbapenem resistant strains can limit seriously the choice of antibiotic therapy. ampc can make resistance to carbapenem and detection of that can be useful for identification of carbapenem resistant. the aim of this study was identification of ampc in most prevalent cause of nosocomia...

Detection of Carbapenemase Production in Gram-negative Bacteria

The greatest threat to antimicrobial treatment of infections caused by Gram-negative bacteria is the production of carbapenemases. Metallo-beta-lactamases and plasmid-mediated serine carbepenemases like Klebsiella pneumonia carbapenemase are threatening the utility of almost all currently available beta-lactams including carbapenems. Detection of organisms producing carbapenemases can be diffic...

Frequency of Multi-Drug Resistance (MDR) in Gram Negative Bacteria from Urinary Infection in Gorgan, 2011-12

Abstract Background and objective: The periodic evaluation of antimicrobial activity of different antibiotic is essential because antibiotic sensitivity pattern may also changed during short courses. The aim of this study was to assess the frequency of Multi-drug Resistance (MDR) in Gram negative uropathogens. Material and Methods: This study was conducted on 111 gram negative uropatho...
