BACKGROUND Over the past several years our laboratories have investigated different aspects of the challenging issue of the alterations in bacterial susceptibility to antibiotics induced by physical stresses. OBJECTIVE To explore the bacterial susceptibility to antibiotics in samples of Salmonella enterica subsp. enterica serovar Typhimurium (S. typhimurium), Staphylococcus aureus, and Klebsi...

the antimicrobial effect of metal nanoparticles such as zinc oxide and silver nanoparticles has been taken into great consideration separately during recent years. the useful application of these nanoparticles in the areas of medicine, biotechnology, and professional prevention of microbes motivated us. the aim of this study was to evaluate antibacterial activity properties of silver doped zinc...

> introduction: escherichia coli is one of the important pathogens in human with global importance. because of the necessity for identification and the use of novel antibacterial compounds against e. coli , in this present study we focused on the antibacterial effects of synthesized thiazole, imidazole and tetrahydropyridine derivatives on e. coli . methods : for evaluation of antibacterial eff...

abstract       background and objective: the spread of drug resistance in bacteria have prompted researchers to seek suitable alternative for antimicrobial drugs among various medicinal plants and nanoparticles. the aim of this study was to evaluate the effect of silver nanoparticles alone and in combination with methanol extract of zataria multiflora on five gram-positive and gram-negative bac...

Background: Despite the availability of a wide range of antibiotics, bacterial infections are among important challenges for the healthcare system. Therefore, the introduction of new antimicrobial preparations such as platelet-rich plasma (PRP) could be suggested theoretically as a preventive measure for bacterial infections. We aimed to evaluate the in vitro antibacterial activity of PRP again...

background: the current study aimed to determine the effect and properties of surface-modified copper doped cu:zno nps on killing curves of bacterial pathogens. m ethods:   preparation  of   in  situ   surface-modified  copper  doped  zno nanoparticles (cu:zno nps) was done according to standard procedure.assay for antimicrobial activity of cu:zno nps against bacterial pathogens was carried out...

background & aim: the aim of this study was to assess the antifungal effect of the watercress extract on the growth of fusarium solani, the causal agent of potato dry rot. experimental:  this research was done in a completely randomized design with three concentrations and four replicates on potato dextrose agar (pda) culture medium. results: results of this study indicated that all conce...

background: the aim of this in vitro study was to assess antimicrobial efficacy of acacia nilotica, murraya koenigii (l.) sprengel, eucalyptus hybrid , psidium guajava extracts, and their combination on streptococcus mutans and lactobacillus acidophilus. materials and methods: the branches of four plants were collected, identified, and authenticated by a taxonomist. the plants were rinsed in wa...
