Abstract
Objectives: To determine changes in antibiotic resistance patterns in E. coli from persons living with
HIV/AIDS (PLWHA). Methodology and results: A total of 264 strains of E. coli were isolated from PLWHA.
The isolates were tested for antimicrobial susceptibility by Kirby Bauer disk diffusion technique. Out of the
216 (81.81%) E.coli from PLWHA and taking antibiotics (HIV+A+), 209-(96.76%), 198-(91.67%) and 188-
(87.04%) isolates were resistant to trimethoprim-sulphamethazole, tetracycline and ampicillin respectively.
All isolates from PLWHA not taking antibiotics(HIV+A-) were sensitive to fluoroquinolones and nalidixic acid
but thirty nine (83.33%) of the them were resistant to trimethoprim-sulphamethazole.The most prevalent
resistance was to trimethoprim-sulphamethazole and ampicillin.
Conclusion and application of findings: prolonged exposure to antibiotic makes PLWHA harbour strains of
E. coli that are significantly more resistant to antibiotics with varying resistance patterns. The findings of
this study should have major implications on public health policy guidelines on managing antimicrobial
resistance in PLWHA, antimicrobial resistance detection modules and intervention schemes. It can also
help in planning regular monitoring of antibiotic resistance patterns in order to provide the basis for
developing rational prescription guidelines.
