Antimicrobial activity of different extracts of bark of Moringa oleifera was studied against ten bacterial strains These bacteria are both gram +ve and gram-ve. Bark were extracted with a petroleum ether, chloroform, ethyl acetate, ethanol and aqueous. In the present work the antibacterial activity was done by cup plate method. The antibacterial activity was expressed as zone diameter in millimeters. Different extracts from bark of the plant was compared with standards like benzyl penicillin for gram +ve bacteria and streptomycin for gram-ve bacteria using DMF as control. The readymade media for inoculum and culture was obtained from Himedia labs. Prepared herbal extracts from the bark of the plant were screened against bacteria organisms at the concentration range between 50 µg and 300 µg/0.1ml. The present investigation reveals that the aqueous, chloroform and ethyl acetate extracts and in some cases petroleum ether extract showed significant antimicrobial activity when compared with standard.
Urinary Tract Infection (UTI) affects various part of the urinary tract. When it affects the lower part it is known as a bladder
infection and when it affects the upper part it is known as kidney infection clinically, presence of more than 1 Lakh
organisms per ml of midstream sample of urine (MSU) is an indication of urinary tract infection. A pain and burning feeling
when you urinate, Urethral discharge containing pus or mucus, Frequent and urgent need to urinate especially at night,
Obstructed urinary flow, Lower back pain, Unexplained fever, Cloudy urine with visible blood are the common symptoms
of UTI. Cranberry, blue berry, berberine, bearberry, buchu oil etc are found to be effective in urinary tract infection. The
fimbriae of E.coli produce two types of adhesins such as mannose sensitive and mannose resistant adhesins that attach to
receptors on uroepithelial cells. Proanthocyanidin obtained from cranberry, blueberry etc shows extreme inhibitory
activity against mannose-resistant adhesins. In bearberry the active antimicrobial activity is shown by aglycone
hydroquinone which is released in alkaline urine. Buchu leaf is a diuretic and urinary tract antiseptic Urinary tract antiseptic
activity is may be due to its essential oil. The essential oil consists mainly of the monoterpene diosphenol.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
