POSPÍŠIL J., OTČENÁŠEK M., POSTUPA J., VEJBORA O., ŠTEINER I. (1989): Trichosporon capitatum as a little known opportunistic mycotic agent in man. Česká Mykologie 43(3): 149-154 (published: 21st August, 1989)
abstract
Transmission of virus-like particles from the infected hypovirulent strain of Cercospora beticola into virulent healthy strains was observed. The joint cultivation of the light poorly sporulating hypovirulent strain C61 containing virus-like particles and dsRNK with dark virulent intensively sporulating C26, C34 and C42 strains without virus-like particles and dsRNA resulted in the rich anastomosis connection between coloured thicker hyphae of virulent strains and thinner hyaline hyphae of the hypovirulent strain. Transmission of virus-like particles and dsRNA via anastomosis from the hypovirulent strain into virulent ones has been proved biochemically by the UV spectra and polyacrylamide gel electrophoresis. Besides, the originally healthy virulent strains have converted and gained the properties of the hypovirulent strain thus demonstrating not only the transfer of virus agent but also its infectivity.

abstract
An orientational survey of taxonomy of fungi which have been described as agents of human mycoses is given. An alphabetical list of 163 agents contains data on synonyms of the individual species and organs afflicted by them. The literature citation of the earliest paper calling attention to pathogenicity is provided. Current nomenclature of anamorph and teleomorph stages and their mutual relation is discussed.
DITRICH O., OTČENÁŠEK M. (1983): A mycological and ecological study of dermatophyte Microsporum persicolor. Česká Mykologie 37(1): 42-48 (published: 1983)
abstract
Microsporum persicolor (Sabouraud 1910) Guiart et Grigorakis 1928 was found in healthy hair of 4.3% of bank voles (n = 163), 0.9% of wood mice (n = 119) and 0.8% of domestic cats (n = 261). The results of the authors’ own isolation experiments were compared with the literature data of this dermatophyte in healthy and afflicted hair of different animal species. The properties of 18 strains of various origin were studied at length in cultivation on special mycological media. The perfect stage — Nannizzia persicolor Stockdale 1967 — was obtained by mating some monosporic isolates.
DITRICH O., OTČENÁŠEK M. (1982): Microsporum vanbreuseghemii and Trichophyton simii in Czechoslovakia. Česká Mykologie 36(4): 236-242 (published: 1982)
abstract
Two dermatophyte isolates not previously reported in Czechoslovakia were obtained from the fur of small mammals. The first, from Sciurus vulgaris, corresponds to Microsporum vanbreuseghemii, and the second, from Microtus arvalis, closely resembles Trichophyton simii. Data on their global distribution suggest they are not strictly endemic. The authors emphasize the importance of mammalian fur for the heterotrophic survival of these fungi.

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.

KŘIVANEC K., JANEČKOVÁ V., OTČENÁŠEK M. (1977): Arthroderma melis spec. nov. - a new dermatophyte species isolated from badger burrows in Czechoslovakia. Česká Mykologie 31(2): 91-99 (published: 1977)
abstract
A new species of the dermatophyte Arthroderma melis was isolated from the burrows of badgers (Meles meles) and described. The small cleistothecia of the perfect state of the fungus are characterized by asymmetric dumb-bell-shaped cells of the peridial hyphae. The imperfect state is distinguished by pink colonies consisting of hyphae with multiple sessile microconidia and single 3–4-celled macroconidia of the Trichophyton type. Intermedial forms of conidia, mostly two-celled, are also typical of the microscopic pattern. The newly described species is not pathogenic for guinea pigs and white mice and is unable to grow at 37°C. It is systematically classified into the A. curreyi group.

abstract
In 132 soil samples collected in Turkey, Iran, Afghanistan, and Pakistan, several keratinophilic fungi were identified, including Microsporum gypseum, Chrysosporium spp., and Trichophyton spp. Eight strains of M. gypseum were pathogenic to guinea pigs. The findings provide insight into the regional distribution and pathogenic potential of soil-borne dermatophytes.
KUNERT J., OTČENÁŠEK M. (1968): Perfect states of Dermatophytes. Česká Mykologie 22(1): 56-67 (published: 1968)
abstract
The paper surveys the perfect (sexual) states of dermatophytes, fungi parasitic on human and animal skin. Over the past ten years, perfect states of 15 dermatophyte species and 4 related keratinophilic fungi have been identified. The authors summarize existing data and include new findings on physiology and genetics.
