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 %).

DESHMUKH S.K., VEREKAR S.A. (2006): The occurrence of dermatophytes and other keratinophilic fungi from the soils of Himachal Pradesh (India).   [Himachal Pradesh, hilly areas, soil fungi, keratinophilic fungi, India]  Czech Mycology 58(1-2): 117-124   (published: 10th August, 2006)
  abstract   Results of a preliminary study of keratinophilic fungi from soils collected from a variety of sites in hilly areas of Himachal Pradesh, India, are reported. A total of 122 soil samples were examined, of which 101 samples were positive for keratinophilic fungi and related dermatophytes. Eleven species of five genera were isolated viz. Chrysosporium indicum (11 %), C. keratinophilum (4 %), C. queenslandicum (25 %), C. tropicum (19 %), Chrysosporium sp. (2 %), C. xerophilum (2 %), Chrysosporium state of Ctenomyces serratus (2 %), Malbranchea gypsea (7 %), Microsporum canis (2 %), Microsporum gypseum complex (9 %) and Trichophyton mentagrophytes (1 %).

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.

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.

ŘEPOVÁ A. (1989): Soil micromycetes from Czechoslovakia - a list of isolated species with bibliography. II.  Česká Mykologie 43(4): 235-243   (published: 17th November, 1989)
  abstract   A list of micromycetes (saprophytic, keratinophilic, rhizosphere, nematophagous, ovicidal, dermatophytes, and cellular slime moulds) isolated from various Czechoslovak soils is presented. 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   A new record of dry rot fungus Serpula lacrimans (Wulf. ex Fr.) Schroet. on the trunk bases of two living trees of Norway Spruce Picea abies (L.) Karst. in the Botanical Garden in Průhonice near Prague is described. Differences between Serpula lacrimans and Serpula himantioides (Fr. ex Fr.) Karst. and the phytopathological significance of the new record are discussed.

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.

  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.
