antimicrobial activity of the polar and nonpolar extracts of the roots and aerial parts of peucedanum ruthenicum m. bieb., johreniopsis seseloides (c. a. mey.) pimenov and cervaria cervariifolia (c. a. mey.) pimenov were examined against gram-positive and gram-negative bacteria. the polar extracts of the roots and aerial parts displayed no activity against bacteria, while the nonoplar extracts ...

Microbe mediated synthesis of nanoparticles is gaining tremendous importance in present time due to its harmless and eco-friendly nature. The present study deals with synthesis of silver nanoparticles using the bacteria Escherichia coli extracellularly and evaluation of its antimicrobial activity. The nanoparticles were characterized by various means like UV Vis spectroscopy, TEM analysis, zeta...

Hexane and methanolic oil extracts from five varieties of Artocarpus seeds were studied to explore its suitability for ethno medical uses. Crude hexane and methanolic oils were found to shown good to moderate activity against bacteria, in particular Gram +ve (Bacillus cereus, Bacillus subtilis and Staphylococcus aureus) and Gram-ve (Eschirichia coli and Pseudomonas aeruginosa) and fungal stains...

Staphylococcus aureus infection is a rather insidious disease. If tests have shown that found on the skin, intestines, ears or nasopharynx, Treatment with pharmaceutical drugs extracted from medicinal plants can be way to get rid of infection. Plants are considered greatest source obtain new antimicrobials. The present study aimed at evaluating in vitro antimicrobial activity methanolic extract...

Gallium is a trivalent semi-metallic element that has shown antimicrobial activity against several important human pathogens. This antimicrobial activity is likely related to its substitution in important iron-dependent pathways of bacteria. The genus Staphylococcus, which includes human and animal pathogens that cause significant morbidity and mortality, requires iron for growth and colonizati...

The synthesis and the biological activity of novel semi-synthetic β-lactam compounds containing an azetidinone moiety joined to the amino-nitrogen of the (+)-6-aminopenicillanic acid (6-APA) as new antibacterial agents is reported. The synthesized compounds were screened for their in vitro antimicrobial activity against a panel of Gram positive and Gram negative pathogens and environmental bact...

A series of 2-(4-nitro-1-imidazolylmethyl)-1,3,4-oxadiazole, 1,3,4-triazole and 3-(4-nitro-1-imidazolylmethyl)-1,2,4-triazole derivatives were synthesized and tested for their antimicrobial activity. Some of the tested compounds were active against Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis, Clostridium difficile, Aspergillus niger and Cryptococcus neoformans.

background and objectives: despite the vast production of new antibiotics in the last three decades, resistance to these drugs by microorganisms has increased and essential oils (eos) have been recognized to possess antimicrobial properties. methods:  in the present study, eos obtained from aerial parts of thymus vulgaris l., lavandula angustifolia mill., rosmarinus officinalis l. and mentha pi...

This study aims to screen the antibacterial activity of lactic acid bacteria (LAB) isolated from home-made fermented vegetables against common food borne pathogens. The antagonistic properties of these isolates against Escherichia coli, Staphylococcus aureus, Yersinia enterocolitica and Bacillus cereus were examined using agar well diffusion method. Four LAB namely MF6, MF10, MF13, and MF15 ide...
