IN VITRO EVALUTION OF ANTIMICROBIAL EFFECTS METHANOLIC AND ACETONE EXTRACTS PEGANUM HARMALA LAVANDULA ANGUSTIFOLIA AGAINST SOME HUMAN PATHOGENIC MICROORGANISM

The in vitro antimicrobial activities of the whole plant extract (ethanolic-CEE) of Chrozophora senegalensis and its fractions (ethyl acetate-EAA, n-butanol-NBE, aqueous-AQE) were assayed using the agar plate diffusion and nutrient broth dilution methods. Test microorganisms were Bacillus subtilis (NCTC 8326 B76), Escherichia coli (ATCC 11775), Pseudomonas aeruginosa (ATCC 10145), Staphylococcu...

Karlová T., Poláková L., Šmidrkal J., Filip V. (2010): Antimicrobial effects of fatty acid fructose esters. Czech J. Food Sci., 28: 146–149. Antimicrobial effects of various fatty acids and their esters have been extensively studied. Esters with saccharides (glucose, sucrose) have been found to have a broad spectrum of microbicidal activity. The objective of this study was to investigate the su...

The therapeutic effects of inhaled nitric oxide (NO) therapy are thought to be restricted to the pulmonary vasculature because of rapid inactivation of NO by hemoglobin in the bloodstream. However, recent data suggest that inhaled NO may not only be scavenged by the heme iron of hemoglobin but also may react with protein thiols in the bloodstream, including cysteine-93 of the hemoglobin B subun...

It has recently been postulated that dietary fibre acts as a substrate for colonic flora, and that the resultant microbial growth bulks the faeces. Antimicrobial therapy was used in this study to assess the effect of reduction in colonic microbial proliferation on faecal output in human subjects on a constant dietary fibre intake. Six healthy young male subjects were maintained on constant dail...

Lactoferrin (Lf) is an 80 kDa iron-binding glycoprotein with multifunctional properties and useful for clinical and commercial applications. Currently, Lf has some advantages including, immune system modulation, antibacterial activity and as antioxidant in infant and adult of human as well as animal health. In the present study, antibacterial activity of Lf has been scrutinized after isolation ...

As members of the indigenous human microbiota found on several mucosal tissues, Methanobrevibacter smithii and Methanosphaera stadtmanae are exposed to the effects of antimicrobial peptides (AMPs) secreted by these epithelia. Although antimicrobial and molecular effects of AMPs on bacteria are well described, data for archaea are not available yet. Besides, it is not clear whether AMPs affect t...

Antimicrobial Peptides (AMPs) were first known as a group of innate immune products that mainly targets on the invading pathogens among multiple species. The essential mechanisms of action of AMPs toward microbial cells have been reported as electrostatic attraction and hydrophobic interaction between AMPs (cationic AMPs) and microbial cell membranes. These effects also contribute to the potent...
