Prevalence of Extended-Spectrum Beta-Lactamases-Producing Microorganisms in Patients Admitted at KRRH, Southwestern Uganda

The emergence of extended-spectrum beta-lactamase- (ESBL-) producing pathogenic bacteria at Kabale Regional Referral Hospital (KRRH), located in southwestern Uganda, is of great concern: a phenomenon that worries clinicians and other healthcare workers due to the serious threat they pose to patients. This current study aimed at determining the phenotypic detection of ESBL-producing strains of E. coli, Klebsiella sp., and Proteus sp. isolated from clinical specimens and their prevalence in patients admitted at KRRH. We used combined disc diffusion technique to detect and establish the presence of ESBLs-producing bacteria. Of the 100 tested bacterial isolates, 89 (89%) were identified as ESBL-producing bacteria. Klebsiella sp. predominated in the samples (46 (52%)), presenting the highest frequency of ESBLs producing followed by E. coli (39 (44%)) and Proteus mirabilis (4 (4.5%)) from the combined disk diffusion.
