Background: Nano scale dendrimers are macromolecules synthetic which frequently used in medical and health field. Because traditional antibiotics inevitably induce bacterial resistance, which is responsible for many treatment failures, there is an urgent need to develop novel antibiotic drugs. This study was aimed to examine Synthesis and the antibacterial effect of NanoPolyamidoamine-G7 (NPAMA...
REP8839 is a selective inhibitor of methionyl-tRNA synthetase (MetRS) with antibacterial activity against a variety of gram-positive organisms. We determined REP8839 potency against Staphylococcus aureus MetRS and assessed its selectivity for bacterial versus human orthologs of MetRS. The inhibition constant (K(i)) of REP8839 was 10 pM for Staphylococcus aureus MetRS. Inhibition of MetRS by REP...
Background and Objective: Staphylococcus epidermidis produces extracellular polysaccharide which is known as a biofilm. Biofilm is highly effective in establishing of this bacterium infections and can be formed on medical devices that are used in the body. The purpose of this study was to evaluate the effects of silver colloidal nanoparticles on bacterial growth and biofilm form...
Background and Aims: Leishmaniasis is an intracellular protozoan- parasitic disease, the common vector of transmission. Both zoonotic and anthroponotic cutaneous leishmaniasis (CL) are endemic in different foci. With regard to the cutaneous form, 1.0-1.5 million cases were reported annually with 90% of the cases. Although antimony-containing compounds that are the main drugs used to treat Leish...
Staphylococcus aureus, as a foodborne pathogen causing significant harm worldwide, was studied to assess the effectiveness of probiotic strains Lactobacillus casei, plantarum, and Bifidobacterium bifidum individually collectively (as consortia) in controlling its growth. The growth patterns S. aureus were observed when co-cultured with each strain consortium all three over 72 hours. Additionall...
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...
background: curcumin as a yellow natural compound extracted from turmeric root is known it as an antibacterial agent. one of the nanoparticles ability is to decrease the defects of usual drug delivery systems. chitosan is a low toxic, biodegradable, biocompatible and safe polymer which is used in production of nanoparticles. nanoparticles like chitosan-tripolyphosphate (tpp) are able to increas...
