Three fractions from the leaves of Moringa oleifera were obtained on Sephadex G-25 column chromatography. Single bands of these fractions were detected on Polyacrylamide SDS gel electrophoresis. An antibacterial action of small protein/peptide was tested against E. coli Kl. aerogenes, KI. pneumoniae, S. aureus, and B. subtilis. Fraction P1, P2 and P3 showed strong inhibitory activity against E....
Shaping organs by a wingless-int/Notch/nonmuscle myosin module which orients feather bud elongation.
How organs are shaped to specific forms is a fundamental issue in developmental biology. To address this question, we used the repetitive, periodic pattern of feather morphogenesis on chicken skin as a model. Avian feathers within a single tract extend from dome-shaped primordia to thin conical structures with a common axis of orientation. From a systems biology perspective, the process is prec...
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...
Regarding the revealing side effect of chemical medications, such as antimicrobial resistance and etc, herbal medications have been considered as one of potential alternative to chemical one. The main purpose of this study was to evaluate the in vitro antibacterial effect of lavender ( Lavandula angustifolia) and ajwain ( Trachyspermum ammi) essential oil on two important rainbow trout bacteria...
Background : To resistant of Enterococcus faecalis to a range of antibiotics, has become one of the concerns of sanitation in most communities and has made many researchers raise identify and using of novel antibacterial compounds against E. faecalis as one of important strategies to control this pathogen. The present study, we assessed the antibacterial effect of thirty new thiazole, thi...
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...
There are many reports about antifungal and antimicrobial effects of Myrtle extract. In respect to resistance of fungal strains to current antifungal drugs such as imidazole derivatives, a comparative study was carried out to Investigate the antifungal effect of Myrtle extract versus clotrimazole on candida albicans, the most common cause of vaginal candidiasis . The vaginal discharge of 500 pa...
Introduction: Choosing the effective disinfectants and using the standard methods of sterilization in hospitals could be useful in decreasing nosocomial infections. The aims of this study were the evaluation of efficacy of new disinfectants including Sanocil, Alprocide, Bibfort, Javel- dose compared with Micro10 and Deconex on isolated organisms from dentistry units. Methods: This was an in ...
In this study the attempt was made to evaluate the antimicrobial activity of various solvent extracts of fruit of Piper longum L. against different gram positive and gram negative bacteria by using disk diffusion method. The petroleum ether extract was resistant towards all the tested bacterial strains while ethyl acetate was highly active. Among all the gram positive bacteria Staphylococcus au...
In this work, the antimicrobial property of nanocomposite prepared by loading of silver nanoparticle onto activated carbon (AgNP-AC) was studied. The silver nanoparticles were synthesized biologically from the culture Enterobacter aerogenes and loaded onto the activated carbon. The nanoparticle and nanocomposite were characterized by UV-vis, scanning electron microscopy and X-ray diffraction st...
