Onychomycosis Caused by Chaetomium globosum
Onychomycosis is usually caused by dermatophytes, but some nondermatophytic molds and yeasts are also associated with invasion of nails. The genus Chaetomium is a dematiaceous nondermatophytic mold found in soil and plant debris as a saprophytic fungus. We report the first Korean case of onychomycosis caused by Chaetomium globosum in a 35-year-old male. The patient showed brownish-yellow discol...
متن کاملIndole Alkaloids from Chaetomium globosum.
Two new indole alkaloids chaetocochin J (1) and chaetoglobinol A (8), along with chetomin (2), chetoseminudin A (3), cochliodinol (9), and semicochliodinol (10), were isolated from the rice culture of the fungus Chaetomium globosum. Their structures were elucidated by spectral analysis. Three new epipolythiodioxopiperazines, chaetocochins G-I (5-7), were identified by the combination of UPLC an...
متن کاملToxicity to rats of corn invaded by Chaetomium globosum.
Of 53 isolates of Chaetomium globosum Kunze isolated from corn, manufactured feed, and fiberboard, grown on autoclaved corn, and fed to rats, 25 were lethal within 4 to 6 days. Thirty-six single ascospore cultures of one isolate were uniformly lethal when similarly grown and fed to rats. Incubation of the fungus on corn for 6 to 8 weeks resulted in greater toxicity than shorter incubation times...
متن کاملPhylogenetic reassessment of the Chaetomium globosum species complex
Chaetomium globosum, the type species of the genus, is ubiquitous, occurring on a wide variety of substrates, in air and in marine environments. This species is recognised as a cellulolytic and/or endophytic fungus. It is also known as a source of secondary metabolites with various biological activities, having great potential in the agricultural, medicinal and industrial fields. On the negativ...
متن کاملCell-wall proteins of Aspergillus niger and Chaetomium globosum.
Cell-wall fractions were obtained from Aspergillus niger and Chaetomium globosum. Non-structural protein was removed by successive washes in urea, NH,OH and formic acid. Amino acid analyses indicated that structural wall proteins were acidic. Aspartic acid was the free amino terminal residue of the protein in both species. Comparison of the ‘maps’ of peptic peptides indicate that there may be s...
