conclusions: with respect to the obtained results and regarding to the daily increase of the resistant microbial strains to the commercial antibiotics, it can be concluded that these extracts can be proper candidates of antibacterial substance against pathogenic bacterial species especially s. aureus, e. coli, k. pneumoniae and s. epidermidis. results: the extract of c. fistula was effective ag...
use of herbal extracts and essences as natural antibacterial compounds has become increasingly popular for the control of oral infectious diseases. therefore, finding natural antimicrobial products with the lowest side effects seems necessary. the present study sought to assess the effect of punica granatum l. water extract on five oral bacteria and bacterial biofilm formation on orthodontic wi...
با افزایش تعداد سویه های باکتریایی مقاوم به آنتی بیوتیک های مختلف و قیمت بالای برخی آنتی بیوتیک ها نیاز به داروهای گیاهی موثر، در دسترس و ارزان احساس می شود. این مطالعه به منظور مقایسه اثرضدباکتریایی عصاره های قطبی و غیر قطبی دوره های مختلف رویشی گیاه اسپند (peganum harmala) بر روی باکتری های آئروموناس هیدروفیلا (aeromonas hydrophila)، فتوباکتریوم دامسلا (photobacterium damsela) و لاکتوکوکوس گا...
the infections risk related to pathogenic germs increases at the present time considering the increased resistance which certain microbes acquire, whose usual antibiotics are ineffective to treat the infectious disease. the aim of this study was to determine antimicrobial effect of the aqueous and ethanolic extracts of lavandula stoechas l. and rosmarinus officinalis l. on listeria monocytogene...
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 ...
A new α-pyrone, 6R-[5R,6S-diacetyloxy-1Z,3E-heptadienyl]-5,6-dihydro-2H-pyran-2one (1), along with six known compounds including an α-pyrone, flavones and terpenes was isolated from the aerial parts of Neohyptis paniculata. The structure of 1 was established unambiguously by MS and a series of 1D and 2D-NMR spectroscopic analyses. The antibacterial activity of the compounds (1-7) was investigat...
The hydroxy metabolite of metronidazole was found to be more active against 21 strains of Gardnerella vaginalis than the parent compound and less affected by culture in carbon dioxide. After 400 mg oral metronidazole (Flagyl) plasma concentrations of the two agents were below the minimum inhibitory concentrations (MICs) for most G vaginalis strains tested. With 2 g metronidazole the plasma conc...
Background & Aim: The aim of this study was to investigate the antimicrobial effects of Zataria multiflora against some Acinetobacter baumannii strains isolated from clinical samples. Experimental: Twelve strains of Acinetobacter baumannii were isolated from referred patients in Zabol hospital. Essential oil of Zataria multiflora...
