Abstract:

An in vitro evaluations were carried out on dried stem bark of Vernonia amygdalina by examining the inhibitory potentials of methanolic and chloroform (methyl trichloride or formyl trichloride) extracts of the plant on some selected gram +ve and gram -ve bacteria, the effects and activities were compared with the activities of some selected standard drugs on cultured medium of these bacteria which are potential causative agents of various public and easily communicable and non-communicable infections. The diameter (mm) of zone of inhibition of the extracts using 200mg/ml was determined on cultured media on four bacterial pathogens.


Keywords: in vitro,Vernonia amygdalina, pathogens, antibiotics.
