ANTIBACTERIAL ACTIVITY OF SOME INDIGENOUS MEDICINAL PLANTS (Pages : 26 - 28)

The study was conducted in the Department of Microbiology, University of Chittagong during February to August, 2008 to identify plant species having potential antimicrobial principles, antibacterial activity from 5 indigenous plant species which were screened from 16 plant species were examined using agar disc diffusion method against ten bacteria (Shigella dysenteriae, Salmonella typhi, Salmonella paratyphi, Bacillus subtilis, Bacillus cereus Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Vibrio cholerae, Bacillus megaterium). The plants were extracted using 95% ethanol and showed the inhibitory effect against grampositive and gram-negative bacteria. But gram-positive bacteria are more sensitive than gram-negative bacteria. The largest zone of inhibition (23mm in diameter) was recorded against Bacillus subtilis with the leaf extract of Blumea lacera.Download
