objective the standard of hygiene in daily life and hospitals can be increased by the use of new antimicrobial fibers, which diminish the danger of pathogenic bacteria. in this study, the antimicrobial effect of special fibers on some staphylococcus isolates was investigated. materials and methods the antimicrobial effect of special type of fibers produced in isfahan poly acryl plant on three s...
The bactericidal activity of five antibiotics for Legionella micdadei was determined by the construction of time-kill curves. Erythromycin, rifampin, penicillin G, cephalothin, and gentamicin were bactericidal for L. micdadei at readily achievable concentrations. The minimal bactericidal concentrations, defined as those producing 99.9% killing within 24 h, were: erythromycin, 4.6; rifampin, 0.1...
serious concerns have been expressed about potential health risks of nano silver containing consumer products (agnps) therefore regulatory health risk assessment on such nanoparticles has become mandatory for the safe use of agnpsinbiomedicalproducts with special concerns to the mutagenic potentials. in this study, we examined the inhibitory and mutagenicity effects of agnps in three different ...
The response of tolerant Streptococcus sanguis and nontolerant Streptococcus mitis infections to penicillin therapy was compared in the rabbit model of endocarditis. The minimal inhibitory and bactericidal concentrations of penicillin were 0.1 and 0.1 mug/ml, respectively, for S. mitis and 0.05 and 6.2 mug/ml, respectively, for S. sanguis. Time-kill studies done in vitro with penicillin concent...
background: one of the main causes of sexually transmitted diseases is group b β- hemolytic streptococci (gbs) multiplying in the genital tracts. penicillin is the most common drug for the treatment of infections caused by these bacteria, but in patients suffering from penicillin allergy, erythromycin and clindamycin are used as alternative therapeutic drugs against gbs. recently, resistance to...
Crude extracts from olive leaves and arugula seeds were screened for its in vitro antibacterial activity. Antibacterial activity was determined by using disc diffusion method against three bacteria (, Staphylococcus aurous and Bacillus cereus). Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) have been determined. Gallic acid was used as a standard drug for th...
