Keywords : Alocasia indicaLinn. Antibacterial activity, Filter Paper Disc diffusion,
Alocasia indica belonging to the family Araceae is widely cultivated in
several parts of India. Antimicrobial activity of different extracts prepared with
petroleum ether, chloroform, acetone, ethanoland water from leaves of Alocasia
indica Linn. is evaluated using “Filter Paper Disc Diffusion Method” against gram
positive,gram negative bacterial strains. Gentamicin (5 ìg/ml) and Fluconazole (5 ìg/
ml) were used as standard for antibacterial assay respectively. Extracts show
significant in-vitro antibacterial activity. Ethanol extract is found to possess potent
antimicrobial activity.

Pityriasis versicolor is one of the most common infections in India commonly
known as Sehuwa (Hypopigmentation) in human skin. It is caused by unicellular
yeast like fungus known as Malassezia. The incidence increases in summers and
monsoon. The phylogenetic relationship of unicellular fungal pathogens has been
studied using ITS1 sequences of the standard strains were aligned by using the
ClustalW computer program. More than 100 skin isolates were collected from
