Abstract
To study endophytic fungi associated with two plant species used as ethno-medicines by aboriginal tribes of
Similipal Biosphere Reserve and evaluation for their antimicrobial potentials against some clinically significant
human pathogens. A total of 458 endophytic isolates were obtained from leaf, stem and fruit tissues of Solanum
rubrum and Morinda pubescence. The dominant endophytic fungi belong to genera Aspergillus, Colletotrichum,
Curvularia and Mycelia sterilia. Maximum endophytic isolates were obtained from leaves segments followed by
stem and fruit tissues. In both the plants class hypomycetes were dominant over other fungal classes. Shannon-
Weiner and Simpson indexes showed rich diversity of endophytic fungi suggesting even and uniform occurrence
of various species. The endophytic isolates showed varying degree of antimicrobial activity against 9 human
pathogens. In S. rubrum 20% and 10% of the isolates inhibited all the Gram-positive and Gram-negative bacteria
and 35% of the isolates displayed antifungal activity against all the test fungal pathogens. One of the isolate
showed considerable antimicrobial activity against all the test pathogens. Endophytic isolates of M. pubescence
showed 24% antibacterial activity against Gram-positive bacteria and 28% antifungal activity against all the test
fungal pathogens. The study revealed that medicinal plants associated endophytes could be a rich source of
antimicrobial agents.
