Antimicrobial effects of six antiseptics and disinfectants were studied against five pathogenic bacteria. Different pathogens responded differently to different antiseptics and disinfectants. Antibacterial effects of the antiseptics and disinfectants were also concentration dependent. Formalin and hydrogen peroxide were highly effective against all the pathogens used while phenyl and iodine wer...
Background & Objective: Food poisonings caused by consumption of domestic dairy products such as cheese due to Escherichia coli (E.coli) and Staphylococcus aureus (S.aureus) are one of the hygienic problems in foodstuffs. Nowadays, using natural preservatives instead of synthetic preservatives in foods has been regarded increasingly and among these natural compounds, medicinal plants comprise t...
Several properties of bio-inspired surfaces like chemical composition, surface topography, surface hydrophilicity and even surface charge could influence bacterial adhesion to implant materials. Therefore, a nanostructured surface is being investigated to avoid bacterial colonization by their physico-mechanical and chemical aspects. Both smooth and rough-surfaced titanium (PT, SLA) and zirconia...
Histidine-rich glycoprotein (HRGP), an abundant heparin-binding protein found in plasma and thrombocytes, exerts antibacterial effects against Gram-positive bacteria (Enterococcus faecalis and Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa). Fluorescence studies and electron microscopy to assess membrane permeation showed that HRGP induces lysis o...
Previously, artesunate (AS) and dihydroartemisinine 7 (DHA7) were found to have antibacterial enhancement activity against Escherichia coli via inhibition of the efflux pump AcrB. However, they were only effective against E. coli standard strains. This study aimed to develop effective antibacterial enhancers based on the previous work. Our results demonstrate that 86 new antibacterial enhancers...
the chemical composition of essential oils isolated from the leaves of cosmos bipinnatus and its antibacterial activity were analyzed by gc-ms and microbroth dilution assay respectively. the essential oil extracted from this plant was predominantly composed of monoterpenes (69.62%) and sesquiterpenes (22.73%). the antibacterial assay showed that the oil had significant inhibitory effects agains...
