HIV causes a decrease in CD4+ lymphocyte cells count, exposing the individual to infections (urinary tract
infections). This study was carried out to determine the prevalence of bacteriuria and antimicrobial susceptibility pattern of
bacteria isolates among HIV patients.
Clean catch mid-stream urine samples were collected from 135 HIV- seropositive patients, cultured on Cystein
lactose electrolyte deficient (CLED) agar and incubated at 370
C for 24 hours. The modified Kirby-Bauer’s disc diffusion
method was used to assess susceptibility to antimicrobial agents.
The prevalence of bacteriuria was 67.4% (91/135). Staphylococcus aureus
was the most predominant (42.9%) isolate,
followed by Escherichia. coli
(24.2%), then Coagulase negative Staphylococci
(10.9%). The highest proportion of bacteria was
isolated from patients having a CD4+ T-cell count of less than 300 cells/mm3
(39.6%). There was an association between
the level of CD4+cell count and bacterial urinary tract infection (P= 0.001). Most sensitive drugs were gentamycin, vancomycin
and amoxicillin-clavulanic acid while the drug with the greatest resistance was sulphamethoxazole-trimethoprim, with
showing 100% resistance to this drug.
Bacteriuria and resistance to commonly used antibiotics is prevalent among HIV/AIDS patients attending the
Bamenda Regional Hospital. Therapy based on antimicrobial susceptibility test is encouraged.
