Antibacterial activity of two cyanobacterial strains i.e. Nostoc polludosum and Cylindrospermum licheniforme was studied. Both cyanobacterial strains were isolated from agricultural fields of Varanasi, India. Crude extracts of both strains in five solvents i.e. Ethanol, Petroleum ether, Acetone, Methanol, and Chloroform were screened against two human pathogenic bacteria i.e. S. aureus and E. c...

The antibacterial activity of some substituted benzimidazole derivatives against Gram negative bacteria Escherichia coli was investigated. The tested compounds displayed in vitro inhibitory activity and their minimum inhibitory concentrations were determined. Quantitative structure-activity relationship has been used to study the relationships between the antibacterial activity and lipophilicit...

In an effort to identify novel antibacterial chemotypes, we performed a whole-cell screen for inhibitors of Staphylococcus aureus growth and pursued those compounds with previously uncharacterized antibacterial activity. This process resulted in the identification of a benzothiazolium salt, ABTZ-1, that displayed potent antibacterial activity against Gram-positive pathogens. Several clinically ...

During the present study the antibacterial activity of Morinda citrifolia leaf, fruit and seed extract was assessed in-vitro by using disc diffusion method. A total of five different accessions of M. citrifolia plants were randomly selected and screened for antibacterial activity against five different bacterial pathogens. Overall analysis of the antibacterial activity of various extracts revea...

background & aim: during human history, most of infectious diseases have been cured with herbal drugs traditionally so that, nowadays, in most developing countries, herbal drugs play an important role in primal remedy. this study has been done according to the appropriate climate and biodiversity of plants in golestan province in order to investigate the antimicrobial activity of alcoholics...

Plants are rich source of antibacterial agents, which could be exploited in human disease management. Aqueous extracts of leaves of 46 plants selected based on an ethnobotanical survey from Mysore region Karnataka (India) were subjected to in vitro antibacterial activity assay against 14 important human pathogenic bacteria employing cup diffusion method. Antibacterial activity of the twelve pla...
