RYBNIKÁŘ A., HEJTMÁNEK M., WEIGL E. (2003): Survival rate of Trichophyton equinum and T. verrucosum mutants at lyophilisation. [lyophilisation, dermatophytes, mutants] Czech Mycology 55(3-4): 273-276 (published: 22nd December, 2003)
abstract
Trichophyton equinum and T. verrucosum mutants were prepared from monoconidial wild-type strains by induction with ultraviolet radiation. The percentage of elements surviving at lyophilisation was approximately the same as or higher than that of relativ ewild-type strain with four of twelve T. equinum mutants and five of nine T. verrucosum mutants. With remaining eight T. equinum mutants and four T. verrucosum mutants the ability to survive at lyophilisation was lower in comparison with the wild-type strains.

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.
KOĎOUSEK R., HEJTMÁNEK M. (1972): Enzymatic activity of spherules of Emmonsia crescens Emmons et Jellison. Česká Mykologie 26(1): 23-24 (published: 1972)
abstract
In the spherules (adiaspores) of 4 strains of the fungus Emmonsia crescens growing on agar medium the activities of the following enzymes were studied: 1. Hydrolytic enzymes: alkaline phosphatase, acid phosphatase, non-specific esterase and aminopeptidase. 2. Respiratory enzymes: lactic dehydrogenase, malic dehydrogenase, glucose-6-phosphate-dehydrogenase, diaphorase and peroxidase.
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).

abstract
Three avirulent mutants with normal spore production were derived from pleomorphic culture of Trichophyton mentagrophytes by means of UV radiation. The characteristics of these mutants are discussed.
