The antimicrobial activity and phenolic compounds of five Finnish honey products against important human pathogens Streptococcus pneumoniae, S. pyogenes, Staphylococcus aureus, and methicillin-resistant S. aureus were analyzed. Microbroth dilution method and HPLC-DAD were used in antimicrobial testing and phenolic compound determination, respectively. Significant antimicrobial activity (p < 0.0...

Aromatic plants are rich in essential oils with considerable antimicrobial properties.The aim of this study was to investigate chemical composition, antimicrobial activity and antioxidant properties of Melissa officinalis and Deracocephalum moldavica essential oils (EOs). The identification of chemical constituents of the EOs was carried out using gas chromato-graphy-mass spec...

background and objectives: entomopathogenic nematodes, belonging to the family heterorhabditis and steinernematidae, are reported to be symbiotically associated with specific bacteria and the secondary metabolites produced by these bacteria possess antimicrobial activity. in this study, bacteria were isolated from nematodes belonging to the family rhabditidae, and the antimicrobial activity was...

Introduction and objective: Dental caries is a common oral bacterial pathology that has been associated with Streptococcus spp., mainly Streptococcus mutans and Lactobacillus spp. Antibacterial activities of Terminalia chebula extracts against several bacterial strains have been reported. The aim of this study was to evaluate the possible antimicrobial potential of T. chebula fruit extracts (ac...

The antimicrobial activity of the diethyl ether, acetone, chloroform, petroleum ether, and ethanol extracts of the lichen Xanthoparmelia pokornyi and its gyrophoric acid and stenosporic acid constituents has been screened against some foodborne bacteria and fungi. Both the extracts and the acids showed antimicrobial activity against Aeromonas hydrophila, Bacillus cereus, Bacillus subtilis, List...

although some venoms and their isolated compounds have been shown to have antibacterial properties, most have not been investigated for such activity. echis carinatus is one of the most venomous snakes in the world and has an effective haematotoxic venom that destroys endothelial cells and causes haemorrhagia. in this study, the antibacterial activity of iranian snake echis carinatus venom agai...

plants are potent biochemists; biologically active compounds present in the medicinal plants have always been ofgreat interest to scientists working in this field. thus, the aim of the current study was to screen the antimicrobial activity of acacia nilotica, ziziphus mauritiana, bauhinia variegate and lantana camara against some selected clinical isolated strains. although previous studies hav...

Introduction: Increasing of food-related diseases has led to the perception of diet importance. Plant-derived products (especially tea) as important sources of antioxidant and antimicrobial compounds play a major role in reducing food pathogens. In this study, total phenolic content, antioxidant and antimicrobial activity of four tea extracts including green tea, white, black and red teas were ...

The antimicrobial activity of copaiba oils was tested against Gram-positive and Gram-negative bacteria, yeast, and dermatophytes. Oils obtained from Copaifera martii, Copaifera officinalis, and Copaifera reticulata (collected in the state of Acre) were active against Gram-positive species (Staphylococcus aureus, methicillin-resistant S. aureus, Staphylococcus epidermidis, Bacillus subtilis, and...
