GANNIBAL P.B., KAZARTSEV I.A. (2013): Development of a PCR assay for amplification of mating-type loci of Alternaria spp. and related fungi. [population genetics, recombination, Ulocladium] Czech Mycology 65(1): 69-78 (published: 10th June, 2013)
abstract
A large number of ascomycete anamorphs including Alternaria spp. are considered asexual, but carry structurally conserved genes in a mating-type locus (MAT1) with two alternate idiomorphs, MAT1-1 and MAT1-2. Since the locus has lost its main function in many species, different directions of natural selection acting on the idiomorphs can be observed. Thus identification of mating types can be used in population biology studies. Also analysis of MAT1 locus sequences is needed for evolution and phylogeny reconstruction. Eighteen primers from previous works and this study were assessed for their ability to amplify MAT1 in 25 Alternaria and 7 Ulocladium, Embellisia and Alternariaster species. The most suitable primer pairs for 6 sections of Alternaria and several Ulocladium species were revealed.
LYSKOVÁ P. (2007): Saprotrophic microscopic fungi and dermatophytes accompanying infections of the skin and nails of patients in the Moravian-Silesian Region (Czech Republic). [saprotrophic microscopic fungi, dermatophytes, superficial mycose, Scopulariopsis brevicaulis] Czech Mycology 59(1): 125-137 (published: 28th June, 2007)
abstract
Over a 19-month period, the spectrum of saprotrophic microscopic fungi isolated from 245 patients in the Moravian-Silesian Region (Czech Republic) was analysed. Saprotrophic microscopic fungi were isolated from nails (90 %) and skin (10 %). None was isolated from hair. The material was the most frequently positive for the presence of Scopulariopsis brevicaulis (32.6 %) followed by Cladosporium sphaerospermum (5.3 %), Aspergillus versicolor (4.0 %), Geomyces pannorum (4.0 %) and others.Dermatophytes and saprotrophic microscopic fungi were both studied within one year and represented 1110 isolates. Dermatophytes were isolated in most of the cases and represented 943 isolations (85 %). The saprotrophic microscopic fungus Scopulariopsis brevicaulis is a known causative agent of onychomycosis. In the evaluation including dermatophytes it ended in the 3rd position with 5.2 % of isolations behind Trichophyton rubrum (80 %) and T. mentagrophytes (8 %).
MOSTAFA M.E., ZOHRI A.A., KOTBY R.S. (2001): Lipid, sterol and ergosterol accumulation in isolates of dematiaceous Hyphomycetes. [Lipid, sterol, ergosterol, dematiaceous hyphomycetes] Czech Mycology 53(2): 149-159 (published: 20th February, 2002)
abstract
Mycelial dry weight, lipid and sterol contents of fungi tested varied with fungalgenus, species and even with isolate of one species. Their dry mass fluctuated between lll.6±l0.7-457.0±41.5 mg/50 ml medium. Lipids, sterols and ergosterol accumulated by the isolates tested ranged from 4.52±0.5-29.04±2.76%, 1.23±0.16-10.63±l.24% and 0.43±0.057-7.13±0.695% of their dry mass, respectively. Cochliobolus spicifer isolate No. 35 was the highest lipid-producer while Ulocladium atrum No. 90 proved to be superior in the production of sterols and ergosterol. TLC technique and chemical analysis of lipid classes produced by U. atrium No. 90 revealed that the lipid fractions are composed of free sterols, free fatty acids, sterol esters, glycolipids, phospholipids and squalene.
ŘEPOVÁ A. (1990): Soil micromycetes from from Czechoslovakia - a list of isolated species with bibliography. IV. Česká Mykologie 44(3): 170-178 (published: 22nd October, 1990)
abstract
A list of micromycetes (including saprophytic, keratinophilic, rhizosphere, nematophagous, ovicidal, dermatophytic fungi, and cellular slime moulds) isolated from Czechoslovak soils is presented with references and data on their distribution. Listed species include Talaromyces flavus, T. luteus, T. purpureus, T. trachyspermus, T. wortmanii, Tetracoccosporium paxianum, Thamnidium elegans, Th. verticillatum, Thielavia basicola, Th. terricola, Thumenella sp.
FASSATIOVÁ O. (1978): Soil micromycetes in abandoned fields in Bohemian Karst. Česká Mykologie 32(4): 226-234 (published: 1978)
abstract
An analysis of soil micromycetes in two abandoned fields in the Bohemian Karst during 1976–1977 revealed 64 species in the younger field (7 years) and 50 in the older (50 years). Dominant species in both were: Penicillium albidum, Fusarium solani, Humicola grisea, Absidia cylindrospora, and Mortierella sp. (section Polycephala). The best isolation method used nylon gauze buried in soil.
