Abstract:
Background: Klebsiella pneumoniae is a bacterial pathogen commonly associated with severe nosocomial and community acquired infections especially through the acquisition of extended spectrum β-lactamases (ESβL) and biofilm formation capacity. The objectives of this study are to determine the prevalence of K. pneumoniae ESβL (KP-ESβL)-producing isolates in the Regional Military University Hospital of Oran (HMRUO) Algeria, characterize their antibiotic resistance profile, genetically detect blaTEM and blaCTX-M genes, and evaluate their biofilm formation capacity.

Abstract:
Background: The rising global emergence of Gram-negative bacteria (GNB) producing β-lactam hydrolysing enzymes in clinical infections constitutes a growing public health threat. This study investigated the occurrence of co-production of extended spectrum β-lactamase (ESβL), AmpC β-lactamases, and carbapenemases among GNB isolated from HIV-infected patients in two tertiary healthcare facilities in southwest Nigeria.
