Abstract
The bacterial organisms were isolated from drinking water (Bacillus, Borchothrix, Clavibacter sp, Ancylobacter sp, and Brevi bacterium). Selected Indian medicinal plants Cardiospermum halicacabum and Melothria heterophylla were selected for antibacterial studies. The solvents used for the extraction of plant ischolar_mains were n- butanol, ethyl acetate and distilled water. The invitro antibacterial activity was performed by agar well diffusion method. The most susceptible Gram-Postive bacteria was Bacillus sp, Brevibacterium sp, and the most susceptible Gram-negative bacteria was Borchothrix sp, Clavibacter sp, and Ancylobacter sp. The extracts of plant Cardiospermum halicacabum and Melothria heterophylla inhibited the growth of the bacterial strains investigated. The most active extracts was compared with the standard antibiotics, penicillin, Streptomycin and Ampicillin 100mg/disc). The results obtained in the present study suggest that Cardiospermum halicacabum and Melothria heterophylla could be used in treating diseases caused by the test organisms. The results are discussed in detail.
