Comparing The Antibacteria Activity Of Ethanolic Extract Of Vernonia amygdalina and Occimum gratissimum with someAntibiotics of choice

Abstract

Aqueous and ethanolic extracts of Vernonia amygdalina and Ocimum gratissimum were assessed for their antibacterial activities at varying concentrations against medically significant pathogenic bacterial strains capable of causing gastroenteritis. The ethanolic extracts showed a better antibacterial potency with diameter of zones of inhibition ranged 1.0±0.33 to 9.33±0.63 (mm).Selected antibiotics of choice were tested against the test isolates and compared with the results of the extracts. The antibiotics had better activity compared to the extracts at the same concentration but relatively comparable at 100% increment of the concentrations of the extracts.
