| evaluation of the inhibitory effect of amphotericin b on the apical growth of f. solani using the biocell-tracer system. | the biocell-tracer (bct) system is an automatic microscopic method used for measuring the growth rate of a single fungal hyphae, which has not yet been applied to study fusarium spp. considering the large resistance of fusarium species to the available chemotherapy and that hyphae is the morphological fungal form most often seen in vivo, in this work, amphotericin b mic and mfc values for a fusarium solani strain were obtained by the conventional assay method testing conidia and also by the bct ... | 2007 | 17472613 |
| quality control and reference guidelines for clsi broth microdilution method (m38-a document) for susceptibility testing of anidulafungin against molds. | the clsi (formerly nccls) m38-a document for antifungal susceptibility testing of filamentous fungi does not describe guidelines for echinocandins. a multicenter study (eight centers) evaluated inter- and intralaboratory reproducibilities of two reading times (24 and 48 h or 48 and 72 h) and two end points (mics and minimum effective concentrations [mecs]) for evaluating anidulafungin against molds. anidulafungin mics (>or=50% inhibition) and mecs (morphological hyphal changes) were determined f ... | 2007 | 17475760 |
| production of fusarium solani f. sp. pisi cutinase in fusarium venenatum a3/5. | fusarium venenatum a3/5 was transformed using the aspergillus niger expression plasmid, pigf, in which the coding sequence for the f. solani f. sp. pisi cutinase gene had been inserted in frame, with a kex2 cleavage site, with the truncated a. niger glucoamylase gene under control of the a. niger glucoamylase promoter. the transformant produced up to 21 u cutinase l(-1) in minimal medium containing glucose or starch as the primary carbon source. glucoamylase (165 u l(-1) or 8 mg l(-1)) was also ... | 2007 | 17505784 |
| expression of matrix metalloproteinases 2 and 9 in experimental corneal injury and fungal keratitis. | levels of matrix metalloproteinases (mmps) can be modulated during corneal infection, but little is known about mmp profiles during fungal keratitis. the purpose of this study was to determine the effect of corneal trauma and immunosuppressive treatment on the expression kinetics of mmp-2 and mmp-9 during experimental keratomycosis. | 2007 | 17525657 |
| fungal neuroinfections: rare disease but unacceptably high mortality. | within last 25 years we have observed 20 cases of fungal meningitis and/or cerebral abscesses. commonest etiologic agens was candida spp. (c. albicans 9 of 20). molds were responsible for 4 cases of brain abscess. mortality was 50% what seems to be very high. extremely high mortality is caused by delayed onset of therapy, severe underlying disease and multiresistant fungal organisms such as mucorales, fusarium solani and aureobasidium. | 2007 | 17558372 |
| comparison of the hydrolysis of polyethylene terephthalate fibers by a hydrolase from fusarium oxysporum lch i and fusarium solani f. sp. pisi. | the hydrolysis of polyethylene terephthalate (pet) fibers by two fungal hydrolases was investigated. the hydrolase from a newly isolated fusarium oxysporum strain (lch 1) was more efficient in releasing terephthalic acid from pet fibers compared to the enzyme from f. solani f. sp. pisi dsm 62420 when equal amounts of p-nitrophenyl butyrate-hydrolyzing activity were employed. pet fabrics treated under the same conditions with the enzyme from f. oxysporum lch 1 also showed a considerably higher in ... | 2007 | 17136729 |

| the role of chitosan in protection of soybean from sudden death syndrome caused by fusarium solani f. sp. glycines. | the in vitro antifungal properties of chitosan and its role in protection of soybean from a sudden death syndrome (sds) were evaluated. chitosan inhibited the radial and submerged growth of f. solani f. sp. glycines with a marked effect at concentrations up to 1mg/ml indicating antifungal property and at 3mg/ml was able to delay sds symptoms expression on soybean leaves for over three days after fungal inoculation when applied preventively. chitosan was able to induce the level of chitinase acti ... | 2007 | 16828285 |
| modification of phenolic metabolism in soybean hairy roots through down regulation of chalcone synthase or isoflavone synthase. | soybean hairy roots, transformed with the soybean chalcone synthase (chs6) or isoflavone synthase (ifs2) genes, with dramatically decreased capacity to synthesize isoflavones were produced to determine what effects these changes would have on susceptibility to a fungal pathogen. the isoflavone and coumestrol concentrations were decreased by about 90% in most lines apparently due to gene silencing. the ifs2 transformed lines had very low ifs enzyme activity in microsomal fractions as measured by ... | 2007 | 16924535 |
| in the aftermath of the fusarium keratitis outbreak: what have we learned? | the 2005-2006 outbreak of fusarium keratitis associated with soft hydrophilic contact lens wear was both unprecedented and unexpected. more than 250 cases have been reported worldwide that have primarily been associated with bausch & lomb renu with moistureloc and, more recently, with bausch and lomb renu multiplus multipurpose contact lens disinfecting solutions. this article documents the outbreak, presenting the time line and the historical and scientific basis for its occurrence. underlying ... | 2007 | 19668512 |
| isolation of autochthonous non-white rot fungi with potential for enzymatic upgrading of venezuelan extra-heavy crude oil. | the increasing world demand for fuels makes it necessary to exploit the largest reserve of extra-heavy crude oil (ehco) of the orinoco oil belt from venezuela. we propose the use of extracellular oxidative enzymes, in particular, lignin-degrading enzyme systems (lds) of fungi, for enzymatic improvement of ehco. autochthonous non-white rot fungal strains able to use ehco, and several polycyclic aromatic hydrocarbons (pahs) as sole carbon source and energy, were isolated from ehco-polluted soils a ... | 2007 | 18833334 |

| modulation of cutinase stability and structure by phospholipid detergents. | fusarium solani pisi cutinase hydrolyses triglycerides of different lengths. here we show that micelle-forming short-chain (c6-c9) phospholipids significantly reduce cutinase stability (both below and above the critical micelle concentration cmc) and rates of folding (only above cmc), trapping cutinase in an inactive state which only regains activity over hours to days, rather than the few seconds required for refolding in the absence of detergent. destabilization decreases with increasing chain ... | 2007 | 17980683 |
