Background and purpose: Decrease in the number of oral microorganisms leads to reduction in caries score. Bacterial therapy, such as using probiotic bacteria, is an alternative procedure in treatment of infections caused by microorganisms. The purpose of this study was to compare the effect of probiotic and non-probiotic yogurt-drink on two common oral microorganisms. Materials and methods: In...

The genus Rhodococcus is gram positive bacterium which was classified into the family of Nocardiaceae. The organism can be isolates from different sources, with capability to degrade diverse types of pollutant. Nowadays, scientists reported a few secondary metabolites which are produced by Rhodococci. Hence, the present study tried to isolate Rhodococci from different soil samples with the cap...
Nowadays, uncontrolled and frequent use of antibiotics may cause emergence of microbial resistanceamong pathogenic agents. Therefore, the use of new synthetic and natural antimicrobial compounds isinevitable. One source of natural compounds in this respect comes from plants. The purpose of this study was to examine the antibacterial effects of peel extracts from sour and sweet pomegranate. Meth...
Antibacterial activity of Fe3O4 nanoparticles was investigated in three microorganisms including P. aeruginosa, E. Coli and Staphylococcus aureus. Fe3O4 nanoparticles were synthesized by chemical precipitation method (20 nm). The Fe3O4 nanoparticles antibacterial effect against Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus were studied by the culture method. First of all, e...
In recent years, the spread of drug-resistant strains of Streptococcus pneumoniae, as the most common causes of bacterial respiratory infections, threatens public health. Therefore, the use of new antimicrobial medicines to inhibit this pathogen is an urgent demand. In this research project, the inhibitory effects of thirty recently synthesized compounds including thiazole, thiazolidine, imidaz...
Background : Nowadays, bacterial infections and antibiotic resistance of their etiologic agents are among the most important challenges facing the health systems. Therefore the application of antimicrobial agents with natural origin has been deeply studied recently. The aim of this study is to evaluate antibacterial effects of aqueous extracts of Ghalghaf and Mazuj galls on gram-negative bacter...
ABSTRACT Background Antibiotic resistance makes antimicrobial peptides (AMPs) agents an alternative for treatment of pathogenic diseases. They are isolated from various animals invertebrates, vertebrates and plants. The present study shows the electrophoretic pattern of protein and peptides from Vicia Faba seed and reports our first attempt to study the antibacterial activity of Vicia faba...
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-...
Abstract Background & Aim: Oral diseases, especially dental caries, are still prevalent in the most developing countries which cost a lot for patients and the health care system. One of the most important ways to reduce costs is to prevent caries. Therefore, the aim of this study was to evaluate the effect of chlorhexidine and fluoride mouthwashes in comparison with Nanosil D1+F combined mouthw...
