Quorum sensing (QS) is a cell density-dependent mechanism used by many pathogenic bacteria for regulating virulence gene expression. Inhibition or interruption of QS by medicinal plant remedies has been suggested as a new strategy for fighting against antibiotic-resistant bacteria. This study aimed to assess the impact of sub-inhibitory concentrations of licochalcone A (LAA) and epigallocatechi...
Algae are composed of a diverse group of various aquatic organisms. Secondary or primary metabolites from these organisms may be potential bioactive compounds of interest for use in the development of new pharmaceutical agents. In this research, four species of marine algae, Ulva lactuca, Padina pavonica, Colpomenia sinuosa and Cystoseira myrica, isolated from Persian Gulf coasts were evaluated...
Bacteriocins are peptides, synthesized on the ribosome of bacteria that show specific antimicrobial activity against a range of bacteria. Among the bacteria producing bacteriocin, the lactic acid bacteria have special emphasis for producing bacteriocins that are not toxic and are easily broken in the mammalian stomach. Therefore, this study evaluated the potential of strains of Streptococcus th...
Saline soils are widely spread in Iran. These intact soils are a great source for the isolation of new bacteria with highly functional metabolites in biotechnology. Actinomycete strains were isolated on starch casein agar and ISP2 with different concentrations of sodium chloride (0, 5 and 10%) from treated soil samples. Pure colonies were cultured on a casein glycerol medium. After complete gro...
Background: Given the concerns about the use of chemical preservatives in food, the consumers and producers have been interested in natural alternatives, such as plant essential oils and extracts. Since there are limited studies about the effect of saffron (Crocus sativus L.) on the behavior of foodborne pathogens in food models, this study aimed to determine the inhibitory effect of aqueous ex...
Objectives:Biofilms are communities of bacteria attached to surfaces through an external polymeric substances matrix. In the meantime, Acinetobacterbaumannii is the predominant species related to nosocomial infections. In the present study, the effect of silver nanoparticles alone and in combination with biocides and imipenem against planktonic and biofilms of A. baumannii was assessed. Materi...
conclusions these extracts can be used as antibacterial agents in treating infectious diseases. further studies are needed for considering this plant as an antibacterial plant and benefit from its clinical applications for routine use. background tagetes genus contains 56 species and is native in north and south america, but some have become widespread around the world. objectives this study wa...
Background and Objectives: Considering the alarming spread of resistance to classic antimicrobial agents, innovative therapeutic approaches to combat antibiotic-resistant pathogens, like the compounds derived from plants and nanoparticles, seems necessary. This study was conducted to investigate the antibacterial effect of biosynthetic silver nanoparticles using Glycyrrhiza glabra and Mentha pi...
The antibacterial activity of ethanol extract of Zingiber officinale Roscoe (ginger) and its combination with different salts like CuSO4, ZnSO4 and MnCl2 was investigated. Both Gram positive and Gram negative bacteria were tested by agar diffusion method. The results showed that ethanol extract of Zingiber officinale gave the maximum zone of inhibition at 50mg/ml concentrations against Escheric...
