Ethanolic extract of endophytic fungi as well as plant extracts were evaluated for in vitro
antibacterial activity by using well diffusion method and their minimum inhibitory concentration
estimated. The culture extract of one endophytic fungus Glomerella acutata EF15 was found to be
potent antibacterial agent against pathogenic coliform bacteria Klebsiella pneumoniae and
Escherichia coli responsible for causing clinical mastitis.
