objective(s): a large ratio of surface to volume of nanoparticles in comparison with bulk ones, will increase the cell penetration and therefore their toxicity. materials and methods: chemical precipitation method was used in order to synthesis of zns:ag quantum dots. their physical properties and characteristics were assessed by x-ray diffraction, ultra violet-visible spectrophotometer, transm...

significant dropping of infectious disease is owned greatly to antibiotic development industry. due to prevalence of drug resistance organisms alongside with other problems, scientists are focusing on medicinal plants. medicinal plants and their antimicrobial components are attractive alternatives for antibiotics. in the present project, the antimicrobial effects of methanolic extract and fract...

The use of medicinal plants for the treatment of various diseases is an old practice in most countries and it still offers an enormous potential source of new anti-infective agents. The present study was conducted to evaluate the antimicrobial activity of Wattakaka volubilis leaf extract. Antimicrobial activity of Wattakaka volubilis methanol extract is determined by disc diffusion method . The...

OBJECTIVES Vancomycin and fosfomycin are antibiotics commonly used to treat methicillin-resistant Staphylococcus aureus (MRSA) infection. This study compares the in vitro inhibitory effects against MRSA of articulating cement spacers impregnated with either vancomycin or fosfomycin. METHODS Vancomycin-impregnated articulating cement spacers and fosfomycin-impregnated articulating cement space...

Anguillospora longissima, isolated from root as endophytic freshwater hyphomycetes, was evaluated for its bioactivity (antibacterial potential) against five bacterial strains, namely, Gram-positive (Bacillus subtilis MTCC 121) and Gram-negative (Agrobacterium tumefaciens MTCC 609, Escherichia coli MTCC 40, Erwinia chrysanthemum, and Xanthomonas pseudomonas). Antimicrobial activity was assessed ...

introduction: to assess the antibacterial effects of an iranian endemic essential oil, satureja khuzistanica jamzad (skj) when used as an intracanal antiseptic and interappointment medicament. materials and methods: antimicrobial activity and minimum inhibition concentrations (mics) of skj essential oil with and without calcium hydroxide (ch) against eleven aerobic, microaerophilic and anaerobi...

background and objectives: bacterial resistance to antibiotics has motivated the researchers to evaluate the novel anti-bac- terial compounds such as some thiazole and imidazole derivatives. thereby, in this work, we investigated the anti-bacterial effects of one new thiazole and two new imidazole derivatives on bacillus cereus , listeria monocytogenes , escherichia coli, salmonella typhimurium...

The present study was conducted to determine the antibacterial activity of Tribulus terrestris against Pseudomonas aeruginosa. Four different concentrations i.e. 15mg/ml, 20mg/ml, 25mg/ml, 30mg/ml of different extract of water and ethanol extracts of Tribulus terrestris were screened for antibacterial activity by disc diffusion method. Ofloxacin was control drug. Ethanol extract of Tribulus ter...

Ethanol extracts from the different parts of B. orellana showed differential antimicrobial activity. It was found that the extracts of in vitro leaves showed maximum activity against Bacillus pumilus followed by the extracts from the roots and hypocotyls. The callus derived from different explants too showed antimicrobial activity. The leaf callus showed maximum activity. The zone of inhibition...
