Abstract Background and objectives: Infectious diseases are the leading cause of mortality in the world. With the increase of Microbial resistance to chemical antibiotics and low side effects of medicinal herbs, it has become of great importance to use herbs as a source of antimicrobial compounds. Material and Methods: In this study, the extract of Trigonella foenum leaf and seed was prepared u...
many medical properties including antimicrobial, anticancer, antioxidant, anti-inflammatory, etc. have been mentioned for Viola odorata. results have shown the solid cell-killing effects of Viola odorata cycloidal compounds. In addition, Pathogen resistance has necessitated the study of new antimicrobial compounds. This study aimed to evaluate the antimicrobial and anticancer effects of aqueous...
Background and Objectives: Lactobacillus spp. are widely distributed in environment as well as dairy products. During the fermentation process, these microorganisms produce various compounds such as organic acids and bacteriocins with antimicrobial activities. The aims of this study were to isolate and identify lactobacilli from local yogurts of Behbahan, Iran, and assessment of antimicrobial a...
Background: The emergence of multidrug-resistant (MDR) strains of P aeruginosa has become a serious concern today. This bacterium is resistant to a wide range of antimicrobial drugs. There are several ways to treat and control infections caused by MDR bacteria. One of these methods is to find active plant compounds with antimicrobial properties and antimicrobial combination of herbal plants ...
Recently, the effects of antimicrobial activity of silver nanoparticles was considered by researcher because of Bacterial resistance to antimicrobial agents in chemical.The aim of this study was to evaluate the antimicrobial activity of the gold nanoparticles on Escherichia coli. Gold nanoparticles are chemically synthesized. Standard strain of E. coli was cultured in a nutrient broth. Minimum ...

ABSTRACT Background and Objective: Lactic acid bacteria are Gram-positive, catalase-negative, nonsporulating, either rod- or coccus-shaped bacteria that have beneficial effects on their hosts by producing antimicrobial substances such as lactic acid, hydrogen peroxide, bacteriocins and biosurfactants. Bacteriocins are antimicrobial peptides that a...
conclusions p. spinosa ethanol extract can be used as a mouthwash for treatment of the oral infections. more clinical and toxicological studies are required for providing its efficacy. results p. spinosa ethanol extract with higher-level phenolic and flavonoid contents showed the highest antioxidant and antimicrobial effects, in comparison with the other extracts. bacillus sp. and streptococcus...
Antimicrobial agents occasionally cause certain adverse effects, such as diarrhea and loose stool, by altering the composition of the intestinal flora. Antibiotic-resistant lactic acid bacteria are used to prevent these adverse effects. Although these bacteria are not resistant to several recently introduced antimicrobial agents, bacterial preparations are still sometimes prescribed concomitant...
Introduction: March medicinal plant with the scientific name of Peganum harmala L., is considered as herbaceous species which is traditionally used as an antimicrobial drug in the treatment of infectious diseases. This study aimed to compare the antimicrobial effect of Peganum harmala smoke and hydrogen peroxide solution on the microbial load in the hospital wards. Methods: This study was a tr...
