STUCHLÍK D., MENCL K., HUBKA V., SKOŘEPOVÁ M. (2011): Fungal melanonychia caused by Onychocola canadensis: first records of nail infections due to Onychocola in the Czech Republic.   [onychomycosis, Arachnomyces nodosetosus, fungal infection, elderly people, soil fungi]  Czech Mycology 63(1): 83-91   (published: 10th August, 2011)
  abstract   Onychocola canadensis is a non-dermatophyte filamentous fungus with an unusual ecology. Hitherto, O. canadensis has been isolated only from human nails and skin, although attempts to isolate it from the environment have been unsuccessful. We describe two new cases of onychomycosis caused by O. canadensis with dissimilar clinical appearance. The first infection manifested itself as distal and lateral onycholysis with conspicuous black pigmentation. As far as we know, this is the first description of O. canadensis onychomycosis in the Czech Republic. In connection with this case, the authors emphasise the importance of mycological laboratory examination of dark nail lesions. Based on photodocumentation, a second case of onychomycosis due to O. canadensis was identified retrospectively.This case manifested itself as distal and lateral subungual onychomycosis with yellow discoloration, which is more typical of O. canadensis onychomycosis. Morphological characteristics important for discrimination of O. canadensis from other medically important fungi are discussed.

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 %).

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.

FRAGNER P. (1987): Microscopical diagnostic of onychomycoses.  Česká Mykologie 41(3): 153-161   (published: 10th August, 1987)
  abstract   Microscopical investigation in medical mycology is not less reliable than cultivation. Group classification is also precise enough in microscopical diagnosis of onychomycoses in KOH preparations with Parker ink (Parker Super Quink, blue-black, permanent). Detailed findings as well as distinguishing features in onychomycoses caused by yeasts, Scopulariopsis and dermatophytes are presented, accompanied by photographs.

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.

FRAGNER P. (1981): Further experience with Castellani’s „Water cultures“.  Česká Mykologie 35(3): 161-164   (published: 1981)
  abstract   Microscopic fungi survive in sterile, distilled water at laboratory temperature for various lengths of time, from less than 11 months (Kloeckera apiculata) to more than 11 years (Sporothrix schenckii). The survival times of some species as well as their spontaneous variability are given. Castellani’s “water cultures” are only an emergency solution for maintaining live collections. Some yeast species which are morphologically or biochemically similar have also similar survival times in water.

FRAGNER P., HEJZLAR J., RUBEŠ M. (1979): Otomycoses and mycoflora of otitides.  Česká Mykologie 33(4): 229-236   (published: 1979)
  abstract   With one third of the patients suffering from otitis there occur microscopic fungi in the ear swabs, but they can be considered agents of the disease in approximately one half of the positive findings only. During the last 15 years, fungi were cultivated from the ear swabs of 472 patients with various ear diseases, mostly otitis externa. The most frequent yeasts in otomycoses were Candida parapsilosis and C. albicans, while the most frequent Aspergillus species were A. fumigatus, A. flavus, and A. niger. Clinical pictures and treatment of some external otitides are briefly mentioned.

BUCHNÍČEK J. (1976): Growth inhibition in Dermatophytes by light.  Česká Mykologie 30(1): 41-48   (published: 1976)
  abstract   The spores and hyphae of dermatophytes are inactivated by ultraviolet light in vitro. The growth of the microcolonies is inhibited by visible light the effect of which may be increased by the photosensibilization. The inhibition degree is lessened depending on the increased wavelength of incident light. The illumination must be started immediately after the inoculation the final effect being increased by repeating the exposures. The resistance of the species and strains examined is different and not well balanced to the spectral ranges investigated.

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.

  abstract   The acidic culture medium with phenol red indicator, as modified from Taplin et al., proved successful. All dermatophytes stained red and also turned the medium red. This medium facilitates and accelerates dermatophyte diagnostics in combination with other conventional media.

FRAGNER P. (1970): Spannweite der Art Trichosporon cutaneum.  Česká Mykologie 24(3): 153-161   (published: 20th July, 1970)
  abstract   Macroscopic and microscopic characteristics, ability to grow at 37°C, arbutin cleavage, starch reaction on Aschner’s medium, and sugar assimilation were studied in Trichosporon cutaneum. Great variability was found among strains. The author proposes treating T. infestans and T. jirovecii as varieties of T. cutaneum.

FRAGNER P., MÚČKA V. (1969): Experiments on the separation and identification of „Rubronigrin“.  Česká Mykologie 23(2): 127-128   (published: 1969)
  abstract   The substance which arises in cultivating mediums by means of the cultivating of Trichophyton rubrum var. nigricans (Fragner 1966) and which has an antibiotic effect on Cryptococcus (Fragner 1965) is not uniform. It is possible to release a basic gas by fast alkalising and warming of the older cultivating medium, which have pH value over 7 owing to the growth of T. rubrum var. nigricans. We determined in this gas dimethylamine by paper and gas chromatography and ammonia by the former of the two methods. The synthetic pure dimethylamine hydrochloride had an antibiotic effect. Our previous (Fragner and Múčka 1966) concentrates obtained by means of distillation were polluted by acrolein arising during dry distillation of glucose from cultivating medium. In younger cultivating mediums with pH ranging from 5.5 to 6.5 there arises — owing to the growth of T. rubrum (with a sharp maximum) — another very unstable substance with antibiotic effect, which we call at the time being “rubronigrin”.
