Ruta graveolens L. is an herbal plant which is traditionally used as an energizer and an anti-bleeding to heal injuries. Regarding increasing prevalence of mycotoxins and inefficiency of methods used to decrease them, it is possible to use plants metabolites to decrease mycotoxins. The antifungal effect of Ruta graveolens on Aspergillus flavus and Penicillium sp. in vitro by disk and well diffu...

A methyl green decolorization micro test for the determination of streptococcal anti-deoxyribonuclease B titers in serum is described. The micro test was compared with an alcohol precipitation macro test on 112 human sera. The anti-deoxyribonuclease B titers agreed within one dilution step for 85.7% of the 112 sera examined by both techniques. Both tests were about equal in the detection of tit...

Background: In this study, we evaluated antibacterial and antifungle activity of these derivatives against gram positive (Staphylococcus aureus, Bacillus subtilis, B. cereus), gram negative (Proteus vulgaris) bacteria and fungale (Candida albicans, C. tropicalis and C. glabrata). Methods: The broth macro dilution and well agar diffusion methods were used for determination of inhibition zoom (I...

vibrio cholerae is a human pathogen that causes mild to severe diarrheal illnesses and has major public health significance. the aim of this study was to investigate the effects of antimicrobial activity of the gold nanoparticles on vibrio cholera. gold and silver nanoparticles are chemically synthesized. standard strain of vibrio cholerawas cultured in a nutrient broth. minimum inhibitory conc...

BACKGROUND An in-vitro study was conducted investigating the antimicrobial efficacy of polihexanide and triclosan against clinical isolates and reference laboratory strains of Staphylococcus aureus and Escherichia coli. METHODS The minimal inhibitory concentration (MIC) and the minimal microbicidal concentration (MMC) were determined following DIN 58940-81 using a micro-dilution assay and a q...

quinazolinone ring system is renown because of its wide spectrum of pharmacological activities due to various substitutions on this ring system. in this study, the minimum inhibitory concentration of the synthesized compounds in our laboratory was determined by micro dilution alamar blue ® assay against six strains of bacteria (three gram-positive and three gram-negative) and three strains of f...

Methods The present study involved the synthesis of gold nanoparticles using a sodium cholate, as both reducing and capping agent and characterization by UVVisible spectroscopy and High ResolutionTransmission Electron Microscopy (HRTEM). The antibacterial activity on significant bacterial species was evaluated by micro broth dilution method. The mechanism for antibacterial action of the gold na...
