Abstract
The study utilizes an experimental quantitative method. It was conducted in the science laboratory 5th floor Administration Building of the University of the Visayas. Antimicrobial activity of the leaf extract of Chinese creeper (Mikania micantha) used in traditional folk medicines were screened against E. coli (Escherichia coli) compared to Tetracycline, pharmaceutical drug. The highest antimicrobial potentially was exhibited by the Tetracyclic drug, followed by the different concentrations (100%, 75%, 50%, and 25%). The leaf extract of M. micantha can be considered to be equally potent as the most common effect antibiotic, such as Tetracycline. A sensitivity test performed with commonly used sensitivity test resulted in the appearance of drug and plant resistance of the bacteria tested. A comparison of data in the inhibition zones of E. coli (Escherichia coli) showed that M. micantha leaf extractand Tetracycline were effective against bacteria strain tested. Furthermore, the results suggest that traditional folk medicine could be used as a guide on the continuing search for new natural products with potential medicinal properties
