Inhibitory activity of Usnea pictoides G. Awasthi (Parmeliaceae) against urinary tract isolates
Journal Title: Scholars Academic Journal of Biosciences - Year 2014, Vol 2, Issue 8
Abstract
The genus Usnea (Parmeliaceae) is one of the best studied lichen genera. The present study aimed at determining inhibitory potential of Usnea pictoides G. Awasthi against bacterial isolates from urinary tract infections. Susceptibility of urinary tract isolates namely Staphylococcus aureus, Enterococcus faecalis and Escherichia coli to lichen extract was determined by Agar well diffusion assay. Minimum inhibitory concentration was determined by broth dilution method. The bacterial isolates were inhibited by lichen extract in a dose dependent manner. Among bacteria, marked susceptibility was recorded in case of E. coli followed by E. faecalis and S. aureus as revealed by MIC values. The lichen can be used for treatment of urinary tract infections.
