today, there is an increasing interest in the use of metal nanoparticles in health sciences. amongst all nanoparticles, the gold nanoparticles have been known to kill the cancer cells under hyperthermic condition by near-infrared frequency electromagnetic waves. on the other hand, although there are different physiochemical methods for disinfection of microbial pollution, however applications o...

The present study investigated the effect of sumac (SWE) and Rosemary water extracts (RWE) on microbial growth in ground beef meat during refrigerated storage. The meat samples were explored for changes in TVC, E.coli (0157:H7) and S.aureus populations. Antimicrobial effectiveness of extracts was more pronounced against Gram-positive strain compared with Gram-negative strain. Antimicrobial impa...

Nanoparticle complexes were prepared from chitosans of various molecular weights (MW) and degrees of deacetylation (DD). The antimicrobial effect was assessed by the Live/Dead BacLight technique in conjunction with confocal scanning laser microscopy (CSLM) and image analysis. Nanocomplexes prepared from chitosans with high MW showed a low antimicrobial effect (20 to 25% of cells damaged), where...

Background: The development of resistance to antimicrobial agents is a major problem in chemotherapy. Finding agents which potentiate antimicrobial activity could be favorable. There are some reports that methylxanthines changed the inhibitory effect of antibacterial agents. Thus, possible synergistic effect of methylxanthines, aminophylline and caffeine on some antibiotics, carbenicillin, ceft...

background & aim: salvia officinalis is known as a traditional medicine for several diseases in countries like lebanon, syria, jordan, etc. in addition, s. officinalis has been subjected to several studies in a try to specify its medicinal effects. this study aims to evaluate the antimicrobial activity of this plant. the aim of the present research was to study antibacterial effects of s. o...

the genus teucrium (germander) belongs to the family lamiaceae, within the subfamily ajugoideae .teucrium polium l. (labiatae) has long been recognized in folk medicine in the treatment of many pathophysiological implications, such as gastrointestinal disorders, inflammations, diabetes and rheumatism. in this study antimicrobial activity of two crude extracts obtained from teucrium polium l. wa...

results the mean of the inhibition zone diameter around the discs of green tea extract in all concentrations was significantly less than 1% sodium hypochlorite (p < 0.001). the antimicrobial effect increased in higher concentrations of extracts of green tea (p < 0.001). conclusions although the antimicrobial effect increases in higher concentrations of extracts of green tea, 1% sodium hypochlor...

The aim of the investigation was to throw light on the question whether drugs other than antibiotics and chemotherapeutic agents exert an antimicrobial effect. In order to elucidate this, the antimicrobial effect of selected psychotherapeutic drugs and their stereo-isomeric analogues was studied. The development of psychotherapeutic drugs from aniline dyes has been reviewed against the backgrou...

BACKGROUND Brucellosis is an infectious disease that is caused by Brucella spp. As Brucella spp. are intramacrophage pathogens, the treatment of this infection is very difficult. On the other hand, due to the side effects of the brucellosis treatment regime, it is necessary to find new antimicrobial agents against it. OBJECTIVES The aim of this study was to investigate the antimicrobial effec...
