Abstract
Medicinal plants play an important role nowadays by taking part in wound healing and to treat pathological conditions. Medicinal plants serve as resource for ingredients in pharmaceutical drug manufacturing. Some herbs used as nutrition, food, perfume, natural dye, pest control. Ayurveda and other Indian literature have mentioned use of herbs. Microorganisms like bacteria, fungi, protozoa, virus, etc. cause various ailments in humans. The disease caused by these microorganisms are treated using antimicrobials. The present study is about antibacterial effect of leaf extract of water hyacinth (Eichhormia crassipes) against Streptococcus pneumonia by using ethanolic extract .Pneumonia is an microbial infection caused by Streptococcal pneumonia ,it can affect lungs and cause sepsis by entering into bloodstream .The plant leaf extract was prepared using deionized water as solvent by Ultrasonic extraction method. The green color extracted product is filtered and placed in refrigerator for contamination free. The microorganism used is Streptococcus pneumonia and the culture medium is made of brain heart infusion broth (pH-7.6), incubated and turbidity adjusted to McFarland standard. The antibacterial activity was carried out by Agar well diffusion method, this leaf extract activity is compared with Teicoplanin potent antimicrobial agent. The antibacterial activity of water hyacinth is indicated by formation of zone of inhibition, it indicates diffusion of compounds into wall of microorganisms. These leaf extract exhibit broad spectrum of antibacterial activity.
