Abstracts of the International Workshop “ONYGENALES 2020: Basic and Clinical Research Advances in Dermatophytes and Dimorphic Fungi”.  Czech Mycology 72(2): 163-198   (published: 10th September, 2020)
  abstract   The ONYGENALES workshop is a bi-annual meeting organised by ISHAM Working Group ONYGENALES (onygenales.org). It brings together researchers, students, clinicians, laboratorians and public health professionals across biomedical disciplines, who are interested in current developments in dermatophyte, dimorphic and keratinophilic fungi research. The abstracts are arranged according to the thematic sessions as they appeared in the programme: Session 1: Antifungal resistance and susceptibility testing, Session 2: Taxonomy of keratinophilic and dimorphic fungi, Session 3: Taxonomy of dermatophytes, Session 4: Population genetics and genomics, Session 5: Emerging and zoonotic pathogens, Session 6: Epidemiology, Session 7: Diagnostics and treatment approaches, Session 8: Virulence factors and pathogenesis

KUNERT J., NOVOTNÝ R. (2002): Degradation of human hair by three soil fungi. An electron microscopic study.   [keratinophilic fungi, keratinolysis, human hair, electron microscopy]  Czech Mycology 53(3): 189-201   (published: 10th January, 2002)
  abstract   Degradation of hair keratin has been studied in three soil fungi differing in keratinolytic ability, viz. Keratinophyton terreum, Dictyoarthrinopsis kelleyi and Fusarium moniliforme. All fungi attacked the hair cuticle forming specialised mycelial organs, fronds, under the scale-like cuticular cells. The cortex was attacked by very thin “boring hyphae”. Their growth was intracellular and perpendicular to the hair axis. In Keratinophyton terreum older boring hyphae branched into complex formations, displayingclearlytic action on keratin. In Dictyoarthrinopsis kelleyi branching was rare and lysis of keratin weaker. In Fusarium moniliforme, a fungus not regarded askeratinophilic, the growth of boring hyphaeceasedearly and the lyticaction remained minimal. All fungi digested the less keratinised parts of the hairs (endocuticle, intercellular substance, interfibrillar matrix) prior to the lysis of hard keratin fibrils.

JANEČKOVÁ V., FASSATIOVÁ O., DANIEL M., KŘIVANEC K. (1977): Findings of soil microscopic fungi in the Himalaya Mountains (Nepal).  Česká Mykologie 31(4): 206-213   (published: 1977)
  abstract   Within the framework of the 1973 Czechoslovak expedition in the Makalu Mountain region in the Himalayas (East Nepal) a total of 43 soil samples were collected for mycologic examination. Fourteen genera with 37 species of soil fungi were isolated from the samples. Though the spectrum of the isolated microscopic fungi was not wide, it contained 2 genera (Acremonium and Tolypocladium) and 15 species described for the first time amongst the Himalayan mycoflora. Some of the species were collected in the area for the second time. Among the keratinophilic microscopic fungi, Chrysosporium lucknowense was isolated. The investigation and the collection of soil samples took place at the altitudes of 1000–4900 m in the sites where the presence of terrestrial mammals was established, or direct from lair openings. The aim was to detect potentially pathogenic or keratinophilic microscopic fungi. Various species of microscopic fungi were isolated for the first time from the extreme climatic conditions of the high mountains characterized by an increased occurrence of UV radiation, great temperature fluctuations, strong air flow, a decrease in the air pressure and oxygen content and extreme abiotic and biotic factors influencing the specific existence of the organisms.

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.
