Nanocrystalline silicon carbide ~SiC! thin films were deposited by plasma enhanced chemical vapor deposition technique at different deposition temperatures (Td) ranging from 80 to 575 °C and different gas flow ratios ~GFRs!. While diethylsilane was used as the source for the preparation of SiC films, hydrogen, argon and helium were used as dilution gases in different concentrations. The effects...

background: cefepime was used as empirical treatment in ventilator-associated pneumonia (vap) induced by gram-negative and gram-positive bacteria. this study aimed to determine the antimicrobial susceptibility pattern of cefepime against microorganism causing vap in mazandaran, north of iran. methods: this study was performed on vap patients diagnosed with clinical pulmonary infection score (cp...

the antimicrobial efficacy of methanol and water extracts of seeds of the plant swietenia macrophylla (family: meliaceae) was evaluated against selected pathogenic bacterial strains (bacillus cereus mtcc 430, klebsiella penumoniae mtcc 109, pseudomonas aeruginosa mtcc 424, escherichia  coli mtcc 443, staphylococcus aureus mtcc 96, salmonella typhimurium mtcc 98, micrococcus luteus mtcc 106) and...

background and objectives : the aim of this study was to evaluate the chemical composition and antimicrobial activity of satureja hortensis and trachyspermum copticum essential oils against different kinds of microorganisms in vitro. material and methods : the antimicrobial activity was evaluated by micro broth dilution assay and analysis of essential oils chemical composition by gc and gc/ms a...

OBJECTIVES To evaluate the BACTEC(TM) MGIT(TM) 960/MGIT Para TB (MGIT) system for drug susceptibility testing of Mycobacterium avium subsp. paratuberculosis (MAP), a pathogen implicated in some forms of Crohn's disease. METHODS MICs of 11 drugs for 10 MAP strains were determined using the MGIT system, the BACTEC(TM)460TB system (BACTEC) and conventional agar dilution methods. RESULTS MICs d...

Fifty-one essential oils extracted from plants of known origin were tested for their antimicrobial activity against three bacteria, Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli and four yeasts, Torulopsis utilis, Schizosaccharomyces pombe, Candida albicans and Saccharomyces cerevisiae using the drop diffusion method. All showed antimicrobial activity against at least one of t...
