Despite in vitro demonstrations of synergism against enterococci, combinations of cephalosporin and aminoglycoside antibodies have been ineffective in the therapy of enterococcal endocarditis. Penicillin-gentamicin, cephalothin-gentamicin, and cefazolin-gentamicin were used to treat enterococcal endocarditis in rabbits. A direct relation was observed between the rate of cure and the degree by w...

Background: Magnetite (Fe3O4) nanoparticles are currently one of the important and acceptable magnetic nanoparticles for biomedical applications. To use magnetite nanoparticles for bacteria cell separation, the surface of nanoparticles would be modified for immobilizing of nanoparticles on the surface of bacteria. Functionalization of magnetite nanoparticles is performed by different s...

   In this study, we report the green synthesis of silver nanoparticles (AgNPs) from extracts of native fruits from Amazonia, Brazil. AgNPs were characterized by UV/Vis and medium infrared (MIR) spectroscopy. Their antimicrobial activities were evaluated against the growth of bacteria and leavers, as well as the evaluation of minimum inhibitory concentration (MIC) and minimum bactericidal c...

background: in this study are submitted the radon concentration measurement results of four underground mines: stanterg, artana, hajvali and badovc, which are owned by trepça enterprise, kosovo. the mines have the same geological formation and from these mines are extracted ores rich with lead, zinc, silver, and gold. the radiation exposures caused by radon and radon daughters was determined an...

toxicity of which on biological wastewater processes, humans, and the environment has been proven in various studies. in this study, the half maximal effective concentration (ec 50 ) of growth inhibition of cadmium, lead, and mercury was assessed on dominant bacterial species present in sequencing batch reactors (sbr). methods: biomass sample was obtained from the biological unit of the sbr est...

Microcin J25 (MccJ25) is a small ribosomally synthesized antimicrobial peptide that is produced by Enterobacteriacea family especially E.coli. The present study focuses on preparation and evaluation of in vitro antimicrobial and biological properties of a new peptide derived from MccJ25. We prepared a MccJ25-derived peptide containing 14 amino acids and a single intra-molecular disulfide bond a...
