The microbial evaluation of Njaba River and its effect on body weight
following consumption was investigated using rats. Water samples were drawn from
tributary, confluence, upstream and downstream points of the river and evaluated.
Bacteria isolated and identified using morphological characteristics revealed
microbial species such as Chromobacteria species, Bacillus species, Pseudomonas
aeruginosa, Proteus species, Staphylococcus epidermides, Escherichia coli,
Klebsiella species, Vibrio cholera, Salmonella species, and Shigella species in the
water samples. Prevalence of the bacterial isolates followed the order downstream
> upstream > confluence > tributary. Water from Njaba River also affected body
weight of test rats significantly (p < 0.05) against the control following consumption.
This study has revealed the microbial evaluation of Njaba River and its effect on
body weight of rats following consumption.
