introduction: due to more resistance of pathogenic bacteria to new and current antibiotics researchers are looking to find the agents of herbal with antimicrobial activities in order to replace chemical drugs. methods: the herbal extract of withani somnifera was done by using a rotary vacuum, 20 strains of pseudomonas aeruginosa were isolated from urinary infections hospitalized patients in cit...

the aim of this study was to investigate the stachys turcomanica phytochemical compounds, antimicrobial and antioxidant activity of methanolic extract. the volatile constituents from the aerial parts of stachys turcomanica growing wild in iran were obtained by hydrodistillation and analyzed by gc and gc-ms. in the gc-ms analysis, forty-six components representing 81.1% of the oil were identifie...

background & aim: by increasing resistance of fish pathogens to chemical drugs, using herbal plants with antimicrobial properties is necessary.in this study, the composition of the essential oil and antimicrobial activity of aerial parts of achillea wilhelmsii c.koch growing wild in zagross mountain (southwest of iran) was analyzed against common bacterial and fungal pathogens of fish. expe...

clarithromycin (clm) is a member of macrolide family with broad spectrum antibiotic activity. it is practically insoluble in water and its poor solubility is ph dependent. in this study, series of nanosuspensions containing clm and stabilizer such as hpmc, nacmc, polysorbate 80, poloxamer 188 and polyvinyl alcohol in various ratios were prepared using sonoprecipitation method. briefly, clm was ...

the in vitro antimicrobial activity of the essential oil isolated from the aerial parts of cymbopogon olivieri (boiss.) bor, an aromatic grass of iran was tested against three gram-negative and four gram-positive bacteria and also three fungi. the results of the bioassays showed that the oil has a remarkable antimicrobial activity. bacillus subtilis and candida albicans were more sensitive to t...

legionella pneumophila is the pathogen responsible for severe pneumonia known as legionnaires’ disease. legionella can live under varied stress conditions, especially in cold environments, and is common in many artificial environments. in this study, the antimicrobial activity of biogenic silver nanoparticles, prepared using the culture supernatant of klebsiella pneumoniae, was evaluated agains...

this study was carried out to evaluate the antimicrobial and antioxidant effectiveness of methanolic extract and different fractions (n-butanol, ethyl acetate, chloroform and n-hexane) of c.intybus seeds. the antimicrobial activity was determined by the disc diffusion method and minimum inhibitory concentration (mic) against a panel of microorganisms (four bacterial strains, i.e. p. multocida, ...
