The descriptions are based on the culture forms occurring in our country. Macroscopic and microscopic appearance, auxanograms, zymograms, growth at 37 °C, data on the pathogenicity for humans and animals as well as these on the origin of the cultures, etc. are given.

FRAGNER P. (1978): Yeasts in human material in our country and their differentiation. Part I.  Česká Mykologie 32(1): 32-42   (published: 1978)
  abstract   A diagnostic system for the determination of yeasts occurring in human material on our territory is presented. It summarizes our experiences gained with more than 15,000 cultures during the last 20 years. According to our procedures it is possible to fairly exactly determine approximately 98% of yeasts within 48 hours or earlier, presuming that pure cultures are at hand. The key is based primarily on assimilation of glucose, galactose, sucrose, maltose and lactose, potassium nitrate assimilation, and macroscopic and microscopic appearance of the cultures. Some groups also use auxanograms of additional carbon sources and zymograms.

Besides two plenary lectures, 8 short communications and 8 posters were presented. In total 32 researchers from the Czech and Slovak Republics took part in the colloquium and discussed various topics important for the further development of experimental mycology.

Colloquium "Fungi as Model Organisms in Research and Biotechnology - II", Olomouc, Czech Republic, September 5th–6th, 2002.  Czech Mycology 55(1-2): 103-149   (published: 23rd July, 2003)
  abstract   The colloquium was a continuation of a previous scientific meeting that took place in Olomouc in 1999 (Czech Mycology 52: 139-178, 2000). It was organised by the joint Commission for Experimental Mycology of the Czechoslovak Microbiological Society and the Czech Scientific Society for Mycology together with the Institute of Biology, Faculty of Medicine of Palacký University, Olomouc. The purpose of the colloquium was to provide a platform for a broad discussion on the use of fungi as model organisms in both basic and applied research. The programme of the colloquium was divided into four parts dealing with the following topics: biochemistry, biotechnology and genetics of fungi; phytopathogenic fungi; fungi pathogenic to humans and animals; and mycology of food and mycotoxins. Each topic was opened with a plenary lecture (30 min.), followed by short communications (10 min.) and accompanied by poster presentations. Besides five plenary lectures, 20 short communications and 24 posters were presented. In total 42 researchers took part in the colloquium and discussed various topics important for the further direction of experimental mycology. Abstracts of the contributions are given here.

FRAGNER P., MIŘEJOVSKÝ P. (1983): Unusual shape of cryptococci in human tissue and in culture. A case of disseminated infection with a survey of cryptococcosis in ČSSR.  Česká Mykologie 37(1): 35-41   (published: 1983)
  abstract   A case of disseminated cryptococcosis was proved by histology and cultivation. Cryptococci in tissue were rather polymorphous: spherical (3–6.5 μm), a bit oval or conspicuously elongated (2.5–4.5 × 5–8.5 μm), dumbbell-, roll-, and rod-shaped (2–2.2 × 4.5–6 μm). Some of them had a weak capsule less than 1 μm in thickness. Cultivated colonies grew glossy and smooth as well as dull and rough. Crude preparations made from the fuzzy border of rough colonies showed a pseudomycelium up to 50 μm long. About 30 preceding Czechoslovak cases of cryptococcosis were reviewed starting from 1954. But one of them was akin in histology to the present case; in another one, there was a rudimentary pseudomycelium in tissue. Literature concerning an atypical shape of cryptococci was commented.

BENDA J., FRAGNER P. (1982): Problems of chronic candida tonsillitis in children.  Česká Mykologie 36(2): 122-127   (published: 1982)
  abstract   In a study of children, Candida albicans was found in 42.7% of oral swabs. Chronic tonsillitis due to yeasts occurred in 3%. Tonsillectomy is considered optimal 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.

FRAGNER P. (1981): Further experience with Castellani’s „Water cultures“.  Česká Mykologie 35(3): 161-164   (published: 1981)
  abstract   Microscopic fungi survive in sterile, distilled water at laboratory temperature for various lengths of time, from less than 11 months (Kloeckera apiculata) to more than 11 years (Sporothrix schenckii). The survival times of some species as well as their spontaneous variability are given. Castellani’s “water cultures” are only an emergency solution for maintaining live collections. Some yeast species which are morphologically or biochemically similar have also similar survival times in water.

FRAGNER P., HEJZLAR J., RUBEŠ M. (1979): Otomycoses and mycoflora of otitides.  Česká Mykologie 33(4): 229-236   (published: 1979)
  abstract   With one third of the patients suffering from otitis there occur microscopic fungi in the ear swabs, but they can be considered agents of the disease in approximately one half of the positive findings only. During the last 15 years, fungi were cultivated from the ear swabs of 472 patients with various ear diseases, mostly otitis externa. The most frequent yeasts in otomycoses were Candida parapsilosis and C. albicans, while the most frequent Aspergillus species were A. fumigatus, A. flavus, and A. niger. Clinical pictures and treatment of some external otitides are briefly mentioned.

FRAGNER P. (1979): Yeasts in human material in our country and their differentiation. Part V.  Česká Mykologie 33(2): 106-117   (published: 1979)
  abstract   Using simplified identification keys, 54 yeast species and two varieties occurring in human clinical material in Czechoslovakia were determined. The revised method is more accurate and economical than previous approaches. Descriptions of eight new species or varieties and diagnostic supplements are included.

  abstract   A study of 45 patients with Candida paronychia and onychomycosis explored disease occurrence, etiology, and therapy. The authors examined mycological findings and evaluated treatment methods. Questions addressed include influences of age, duration of disease, causative agents, and recurrence.

PILÁT A. (1967): Sunt Tremellae affines fungis saccharomycetiformibus generis Cryptococcus?  Česká Mykologie 21(3): 196   (published: 1967)
  abstract   The author discusses the taxonomic relationship between the jelly fungi Tremella and yeast-like fungi of the genus Cryptococcus. Evidence suggests that haploid yeast-like forms of Tremella resemble Cryptococcus and produce similar extracellular polysaccharides, implying a possible evolutionary connection.

FRÁGNER P. (1966): Trichophyton rubrum (Cast.) Sabouraud var. nigricans var. nova.  Česká Mykologie 20(1): 27-28   (published: 1966)
  abstract   Trichophyton rubrum (Cast.) Sabouraud var. nigricans var. nova differs from the typical form by producing a dark brown pigment and an antibiotic effective against Cryptococcus. Cultures were obtained from diseased nails and skin. The fungus shows no significant microscopic differences from the typical form.
