Abstract
Background: Globally, extended-spectrum beta-lactamase-producing and carbapenem-resistant Enterobacterales are major causes of hospital-acquired infections and there are increasing concerns about their role in community-acquired infections.
Objective: We aimed to investigate the prevalence of extended-spectrum beta-lactamase-producing Enterobacterales (ESBL-PE) and Carbapenemase-producing-Carbapenemresistant-Enterobacterales (CP-CRE) and associated factors in community settings in Gulele sub city, Addis Ababa, Ethiopia.
Methods: A cross-sectional study was conducted among 261 healthy individuals. Stool samples were collected and processed using standard microbiological methods. Antimicrobial susceptibility and phenotypic ESBL and carbapenemase tests were performed. Antibiotic resistance genes were detected by Polymerase Chain Reaction (PCR).
Results: The colonization rate of ESBL-PE and CP-CRE were 31.4% (82/261, 95% CI: 25.91-37.48) and 0.8% (2/261, 95% CI: 0.13-3.1), respectively by phenotypic method. Molecular detection of genes for ESBL-PE was 27.9% (73/261, 95% CI:22.7-33.9), and for CP-CRE was 0.8% (2/261, 95% CI: 0.13-3.1). The most prevalent genes were blaTEM [76.7% (56/73)] and blaCTX-M [45.2% (33/73)]. Previous antibiotic use (AOR:2.04, 95%CI: 1.35-4.41, P:0.041) and age between 42 and 53 years old (AOR:3.00, 95%CI:1.12-7.48, P:0.019) were significantly associated with ESBL-PE colonization.
Conclusion: Intestinal colonization by ESBL-PE harboring the associated antibiotic resistance genes was substantially high but with low CP-CRE. Continued surveillance of community-level carriage of antimicrobial resistance Enterobacterales is warranted.
