Abstract

The aqueous and ethanolic extracts of Launaea procumbens check for this species in other resources Roxb. (Labiateae), Vitis vinifera check for this species in other resources L. (Vitaceae) and Cyperus rotundus check for this species in other resources L. (Cyperaceae) were evaluated for antimicrobial activity against clinically important bacteria viz. Alcaligenes faecalis check for this species in other resources ATCC8750, Bacillus cereus check for this species in other resources ATCC11778, Bacillus subtilis check for this species in other resources ATCC6633, Enterobacter aerogenes check for this species in other resources ATCC13048, Escherichia coli check for this species in other resources ATCC25922, Klebsiella pneumoniae check for this species in other resources NCIM2719, Proteus mirabilis check for this species in other resources NCIM224, Proteus vulgaris check for this species in other resources NCTC8313, Pseudomonas aeruginosa ATCC27853, Pseudomonas pseudoalcaligenes ATCC17440, Salmonella typhimurium ATCC23564, Staphylococcus aureus check for this species in other resources ATCC25923, Staphylococcus epidermidis check for this species in other resources ATCC12228, Staphylococcus subfava check for this species in other resources NCIM2704 and Candida tropicalis check for this species in other resources ATCC4563. The in vitro antimicrobial activity was performed by agar disc diffusion and agar well diffusion method. The ethanolic extracts of all the plants were active against all the investigated bacterial strains while all the aqueous extracts were inactive except for Vitis vinifera L. S. typhimurium was the most resistant bacterial strain against all the extracts
