LENHART K., WEIGL E. (1971): Macroconidia of mutants of Trichophyton ajelloi (Vanbreuseghem 1952) Ajello 1968. Česká Mykologie 25(1): 55-56 (published: 28th January, 1971)
abstract
Nine mutants of Trichophyton ajelloi derived from strain 205 were studied for macroconidial size and shape. Despite major morphological changes, macroconidial features remained stable. The findings suggest that macroconidial morphology is a reliable character for species identification in dermatophytes.
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.
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.
RYBNIKÁŘ A., DITRICH O., PYTELA F. (1983): Lyophilization of some cultures of dermatophytes. Česká Mykologie 37(2): 93-98 (published: 1983)
abstract
The effect of lyophilization on the viability of germs of eleven species of dermatophytic fungi was studied. Cultures composed mainly of microconidia retained viability, while those composed of hyphae, macroconidia, and chlamydospores showed reduced viability. No changes in morphology or virulence were observed. For Trichophyton verrucosum, viability dropped by 20–78% after five years of storage at 4°C.
HUBÁLEK Z., ROSICKÝ B., OTČENÁŠEK M. (1979): Fungi on the hair of small wild mammals in Czechoslovakia and Yugoslavia. Česká Mykologie 33(2): 81-93 (published: 1979)
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.
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
Three species of Chaetomium—C. brasiliense, C. incomptum, and C. rectangulare—are reported from India for the first time. They were isolated during studies of coprophilous fungi near Delhi and identified through morphological comparisons with original descriptions and specimens.
HEJTMÁNEK M., LENHART K. (1970): Contribution to faviform variability and pathogenicity of dermatophytes. Česká Mykologie 24(4): 192-197 (published: 29th October, 1970)
abstract
The faviform UV-mutants of Microsporum cookei, Trichophyton ajelloi and Trichophyton mentagrophytes are described. Two of the eight faviform mutants of T. mentagrophytes were pathogenic for guinea pigs, the others were non-pathogenic. The changed morphology of faviform mutants derived from T. mentagrophytes was permanent even after recultivation from animal lesion. The authors classify faviform changes known up to now into three categories: 1. Faviform modifications (reversible reaction of culture on specific environmental factors). 2. Faviform mutations (irreversible changes of cultures). 3. Syndrome of faviform senescence (spontaneous change in old cultures of dermatophytes probably caused by mutation in cytoplasmic or nuclear determinant).
