3.1. Antimicrobial activities
The antimicrobial activity of the H. sabdariffa extract
was evaluated on eight different uropathogenic bacteria.
Significant antimicrobial effects, expressed as various
concentrations of the extract, were observed against all the
uropathogenic isolates and the control strains. MIC values
ranged from 0.5 to 4±0.00 (SD) mg/mL, and MBC values ranged
from 8 to 64±0.00 (SD) mg/mL. In general, E. coli strains were
more sensitive than K. pneumoniae against the extract. The
results of the antimicrobial activities are presented in Table
