From this investigation, the aqueous extracts of P. guineense
and O. gratissimum showed minimal antibacterial
activity against the isolates at 10 mg/ml-1 concentrations.
This observed difference between these plants extracts
may be due to insolubility of active compounds in water
or the presence of inhibitors to the antimicrobial components madioha and
Obi reported that inactivity of plant extracts may be
due to age of plant, extracting solvent, method of extraction
and time of harvesting of plant materials. Conversely,
the ethanol extracts of P. guineense and O. gratissimum
showed a concentration dependent gradient decrease in
the level of inhibition against isolates From the results
there is variation in the degrees of antibacterial activities
of the extracts on the isolates
