abstractpropionibacterium acnes is propounded as one of the significant factors in occurrence of acne. today, due to development of the antibiotic resistance, most of the acne treatments are faced with failure. in order to determine the antibiotic resistance of the p.acnes strains isolated from the patients with acne, this research has been carried out. 70 samples collected using microbial cult...
objective: this study aims to evaluate the antimicrobial activity, phytochemical studies and thin layer chromatography analysis of machine oil, hexane extract of seed oil and methanol extract of presscake& latex of jatropha curcas linn (family euphorbiaceae). materials and methods: j. curcas extracts were subjected to preliminary qualitative phytochemical screening to detect the major phytochem...
we consider of the antimicrobial activity on the ag nanoparticles(ag nps) aqueous solutions, which was prepared using a stabilizer, such as poly(n vinyl 2 pyrrolidone pvp , for staphylococcus aureus) s aureus and escherichia coli e coli by measuring the minimum inhibitory concentration mic . antimicrobial effect of ag nps for s aureus and e coli was investigated using disk diffusion method also...
abstract background and objective: enterococci are relatively nonvirulent bacteria that rarely cause disease. antimicrobial treatment of enterococci is often challenging due to their antibiotic resistance. this study aimed to investigate the antibacterial activity of aqueous extract of garlic against enterococcal isolates. methods: in this descriptive study, 120 enterococcus isolates ...
Introduction: Nowadays the medical, therapeutic and pharmacological application of magnetic fields (MF) and its biological effect has raised question about the safety of MF. This study aimed at scrutinizing the effect of static MF on the resistance of S. aureus to antibiotic. Materials and Methods: This prospective, case–control study was conducted to evaluate the e...
Background & Objective: Staphylococcus aureus and Salmonella typhimurium are among important causes of infection and antibiotic resistance. It is essential to find antimicrobial compounds against them. The objective of this study is to evaluate the antibacterial activity of Lecanora muralis SP. extracts on Staphylococcus aureus and Salmonella typhimurium in in-vitro and in animal model.Ma...
Antibiotic tolerance and persistence are often associated with treatment failure and relapse, yet are poorly characterized. In distinction from resistance, which is measured using the minimum inhibitory concentration metric, tolerance and persistence values are not currently evaluated in the clinical setting, and so are overlooked when a course of treatment is prescribed. In this article, we in...
Antimicrobial properties of chitosan extracted from indigenous shrimp processing waste were determined against one gram-negative (Salmonella Paratyphi) and one gram-positive bacterium (Staphylococcus aureus) in vitro. The antimicrobial activities of chitosan were explored by calculation of the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) in media supplemen...
background and objectives: recently, use of herbal medicine and plant extracts as a substitute for commercially available chemical drugs for control of infectious diseases such as dental caries and periodontal disease has become increasingly popular. the present study was aimed to evaluate the effect of rhus coriaria l. water extract on five common oral bacteria and bacterial biofilm formation ...
dental caries, periodontitis and other mucosal diseases are caused by a complex community of microorganisms. this study aimed to investigate the antimicrobial properties of saponins of four important oil yielding medicinal plant extracts on selected oral pathogens that are involved in such diseases.saponins were extracted from bauhinia purpurea, madhuca longifolia, celastrus paniculatus and sem...
