KRUPODOROVA T., BARSHTEYN V., KIZITSKA T., RATUSHNYAK V., BLUME Y. (2023): Antagonistic activity of selected macromycetes against two harmful micromycetes.   [ascomycetes, Aspergillus niger, basidiomycetes, dual-culture, Penicillium polonicum.]  Czech Mycology 75(1): 85-100   (published: 23rd June, 2023)
  abstract   Competition between 31 macromycete species and two harmful micromycetes Aspergillus niger and Penicillium polonicum was evaluated using dual-culture plate assay. All investigated fungi, except for Inonotus obliquus and Lepista luscina, possessed different levels of antagonistic activity against the tested micromycetes. Hypsizygus marmoreus and Lyophyllum shimeji were inactive against A. niger. Morchella esculenta and Oxyporus obducens were passive in the case of co-growth with P. polonicum. The study of fungal interactions showed variability in types of reactions and level of their visualisation. Co-cultivation of the studied species resulted in the following reactions: deadlock after mycelial contact and at a distance, partial or complete replacement after initial deadlock on contact. In general, the studied macromycetes showed moderate activity against the two micromycetes, as 11 species showed active and 7 species moderate antagonism. Results revealed higher antagonistic activity of macromycetes against P. polonicum than in A. niger co-cultures. Wood-decaying species Ganoderma lucidum and Trametes versicolor were the most active fungi against the two tested micromycetes with a maximal antagonism index. These findings provide valuable insights which can be further explored by means of in vivo assays to find a suitable agent for the biocontrol of diseases or spoilage caused by A. niger and P. polonicum.

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 %).

NASSER L., ABDEL-SATER M.A. (1997): Fungi associated with sheep hairs in Saudi Arabia.   [Keratinophilic, non-keratinophilic fungi, sheep hairs]  Czech Mycology 50(2): 99-106   (published: 16th December, 1997)
  abstract   The frequency of occurrence of fungi in 25 hair samples of nine kinds of sheep, collected from different localities in Saudi Arabia, was estimated using three isolation methods at 28°C. Fortyfive species and one variety representing 23 genera were isolated and the most common genera were Chrysosporium, Alternaria, Aspergillus and Penicillium. The most prevalent species of the above genera were C. indicum, C. tropicum, Alternaria alternata, Aspergillus flavus, A. fumigatus, Penicillium chrysogenum and P. oxalicum. Other fungi were also isolated with variable frequencies.

VOLLEKOVÁ A. (1990): Anixiopsis stercoraria - a rare agent of human dermatomycoses.  Česká Mykologie 44(3): 147-151   (published: 22nd October, 1990)
  abstract   Anixiopsis stercoraria, a keratinophilic ascomycete, is globally distributed in soils and has recently been sporadically recorded as a cause of human dermatomycoses. Lesions are clinically indistinguishable from dermatophytoses. Six strains isolated from patients with suspected dermatomycoses were examined; five were considered incidental findings. Morphological features and cleistothecia formation on various media are described.

The paper includes distribution data and literature citations for each species. It is the second installment of the series and documents a wide variety of fungi, including Chaetomium species and other frequently encountered genera.

VOLLEKOVÁ A. (1985): Keratinophilic fungi in rodents‘ burrows and in their adjoining surroundings.  Česká Mykologie 39(2): 97-105   (published: 1985)
  abstract   A group of 150 women suspected of mycotic colpitis was examined. Mycological cultures were positive in only 52%. False positives from routine microscopy were noted. Species of yeast, clinical symptoms, findings in oral cavity and rectum, and perianal lesions were reported. Mixed infections were discussed. Patients were treated with vaginal and oral Nystatin. Mycological negativity occurred in 43% of pregnant and 75% of non-pregnant women; complete cure in 24% and 33% respectively. After delivery, 78% of women recovered spontaneously without treatment.

HUBÁLEK Z. (1981): A systematic survey of dimorphic and polymorphic fungi.  Česká Mykologie 35(4): 209-226   (published: 1981)
  abstract   Various definitions of the term dimorphism in fungi are briefly discussed and a general concept is given with a suggested morphological classification of the dimorphism. Dimorphism (and polymorphism) is delimited as an environmentally controlled reversible phenotypic duality (or plurality in the case of polymorphism) in the morphogenesis of the vegetative fungal cells, which is not restricted to pathogenic species and to the mycelial-yeast transitions only. A systematic list and an alphabetical index of the fungi exhibiting the phenomena of cellular dimorphism or polymorphism are presented.

  abstract   The brown rust infecting Agropyrum species in Czechoslovakia consists of two ecologically and morphologically distinct units, proposed as Puccinia persistens subsp. persistens var. persistens and subsp. agropyrina comb. nov. Rust on wheat is treated as var. triticina.

HEJTMÁNEK M., HEJTMÁNKOVÁ N. (1976): Fluorescence microscopy of hyphal nuclei.  Česká Mykologie 30(1): 20-23   (published: 1976)
  abstract   A method of fluorescence staining of hyphal nuclei in 32 species of fungi is described. It also permits observation of nuclei in conidia and septa. The latter can be safely distinguished by combining fluorescence under incident UV light with phase contrast under penetrating light. This method is applicable to quantitative evaluation of nuclear ratios in mycelium of Phycomycetes, Ascomycetes, Basidiomycetes, and Deuteromycetes.
