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...
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...
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...
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...
conclusions results of this study suggest that the extract alone of peganum harmala and heracleum persicum may be useful to treat bacterial infections. objectives the major aim of the current study was to investigate the antimicrobial activity of an extract of the peganum harmala flower and heracleum persicum against acinetobacter baumannii. materials and methods the minimum inhibitory (mic) co...
background and aim: in recent years, due to the indiscriminate and irrational use of synthetic drugs, the resistance of pathogenic microorganisms has increased; therefore, new compounds are vitally needed. the purpose of this study was to investigate the effect of ethanolic and aqueous extracts of berberis vulgaris on escherichia coli, klebsiella pneumoniae, proteus mirabilis, citrobacter frund...
recreational waters should be considered as risks for enterococcal infections in regions with high utilization and long exposure periods. the aim of this study was to investigate the resistance of enterococci to selected antibiotics and some heavy metals [pb+2, fe+2, zn+2 and cr+2]. a total of 75 enterococcal isolates was obtained from 54 bathing and fishing water samples from 9 bathing and fis...
it seems that rapid destruction of gram negative bacteria by antibiotics contributes to the clinical deterioration of some patients with gram negative infections. antibiotics increase the concentration of lipopolysaccharide (lps) in blood and cerebrospinal fluids. released lps can activate blood cells to produce tumor necrosis factor-alpha (tnf-a) and other cytokines. tnf-a appears to be a majo...
Antimicrobial efficacy of flavonoids (free and bound) and crude alkaloids of Lantana camara L. was determined by disc diffusion assay against three bacteria (Escherichia coli, Proteus mirabilis, and Staphylococcus aureus) and two fungi (Candida albicans and Trichophyton mentagrophytes). Minimum inhibitory concentration, minimum bactericidal/fungicidal concentration and total activity were also ...
