KOCKOVÁ-KRATOCHVÍLOVÁ A., PETROVÁ M. (1959): The occurence of yeasts and yeast like microorganism in the montainous region of Malé Karpaty.  Česká Mykologie 13(1): 37-50   (published: 20th January, 1959)

SLÁVIKOVÁ E., VADKERTIOVÁ R. (1995): Yeast population in the water of a polluted fish-pond.   [Yeast population, polluted fish-pond, Slovakia]  Czech Mycology 48(2): 145-154   (published: 25th September, 1995)
  abstract   The present paper reports the results of a qualitative and quantitative investigation of yeast populations isolated from the water of one fish-pond near Bratislava. Quite a number of fish have perished from disease in this pond. Eighteen different yeast species with various cell densities were identified from one hundred and fifteen water samples. Aureobasidium, Sporobolomyces, Trichosporon, Candida and Cryptococcus species occurred most frequently. The yeast populations of autumn and summer samples are compared. The total yeast count was 11 times higher in autumn than in summer. The distribution and densities of Trichosporon cutaneum, Geotrichum candidum, and to a certain degree of some species of the genus Candida, indicate the predominance of yeasts typical of a polluted aquatic environment.

SLÁVIKOVÁ E., VADKERTIOVÁ R. (1993): Ecological studies on yeasts in fish-ponds.  Česká Mykologie 46(3-4): 272-281   (published: 25th August, 1993)
  abstract   Investigations of yeasts isolated from 126 water samples show the occurrence of 16 different species. Two small fish-ponds were sampled twice, in summer and autumn, respectively. The most prevalent species were Aureobasidium pullulans, Sporobolomyces roseus, Hansenula anomala, Hyphopichia burtonii, Leucosporidium scottii, Bullera alba and Candida sp., mainly Candida krusei. The comparison is noted between the yeast population of autumn and summer samples. The total yeast count was 2.5 times higher in autumn than in summer. Isolated yeast strains are characterized by some physiological features.

SLÁVIKOVÁ E., KOVAČOVSKÁ R., KOCKOVÁ-KRATOCHVÍLOVÁ A. (1991): The incidence of yeast organisms in the water of the artificial lake in Jakubov (Slovakia).  Česká Mykologie 45(3): 103-111   (published: 31st October, 1991)
  abstract   The present paper reports the results of qualitative and quantitative investigation of yeast populations in freshwater of the lake in Jakubov, located in the middle of the Lowland of Záhorie. One hundred and twenty-eight samples offered the possibility to isolate seventy-three yeast strains belonging to twelve genera. Representatives of the genera Candida, Hansenula, Aureobasidium and Rhodotorula occurred most frequently. The occurrence of yeast species at the beginning of the season was twice as heterogeneous as after it. Isolated yeast strains are characterized by some physiological features.

  abstract   The occurrence of yeasts in the artificial recreational lake Rudava, located in the middle of the Záhorie Lowland, was studied. Twelve different yeast species were identified from sixty water samples, including Candida krusei, C. tropicalis, C. guilliermondii, Geotrichum candidum, Rhodotorula glutinis, Rh. rubra, Hansenula anomala, Aureobasidium pullulans, Cryptococcus albidus var. aerius and Saccharomycopsis fibuligera. Their likely sources include swimmers, sewage, decomposed wood and plants, or animal feed. Some species are potentially pathogenic to humans or animals.

FRAGNER P. (1985): Keys for identification of yeasts from human material according to new points of view.  Česká Mykologie 39(4): 234-242   (published: 8th November, 1985)
  abstract   Identification keys were presented for 46 yeasts from human material in this country. Based on the author's own cultures and experience, they conform with the modern monograph by Kreger-van Rij et al. Some new trends and issues in yeast diagnostics are also addressed.

FRAGNER P., ŠKOPEK J. (1982): Incidence of yeasts in the mouth cavity in person with removable dentures.  Česká Mykologie 36(3): 166-172   (published: 1982)
  abstract   Coprinus laanii Kits van Waveren is described with its cap initially egg-shaped or ellipsoid, later bell-shaped, 5–10 mm high, 3–8 mm wide, and finally nearly flat. Initially white and covered with fine greyish powder, the cap becomes striated and torn at maturity. Gills are white to almost black, narrow, and not crowded. The stem is 10–30 mm long, 1–2 mm thick, white with greyish powder that later falls off. Spores are 10–14 × 7.5–8.5 µm with thick irregular perispore and ornamentation of transverse ridges. The veil is composed mainly of spherical or broadly ellipsoid cells. This fungus was recorded as a new finding in Czechoslovakia.

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., ŠIMKOVÁ M. (1980): Yeasts in children.  Česká Mykologie 34(2): 82-91   (published: 1980)
  abstract   Altogether 400 children in the age of 0–8 years, hospitalized because of various diseases, were examined. Yeasts were demonstrated in 58.3% children in the tongue, buccal mucosa, tonsils or rectal swabs. Lists of the species found at different localizations are given. Candida albicans (alone or in combination with other yeasts) was found in altogether 47.5% patients; on the tongue in 41.8%, on the buccal mucosa in 38.3%, on the tonsils in 50.8% and in the rectum in 20.3%. With respect to the findings of C. albicans in rectal swabs there exists a rule that C. albicans is nearly always present in the mouth as well. Mouth findings need not be accompanied by findings in the rectum. Clinical picture of soor in the mouth cavity was observed in 1.5% children only. Possible connections between the incidence of yeasts and various clinical changes were followed. Especially important are the findings of yeasts in connection with the general health condition of the children: in the group with abundant and massive C. albicans findings most children are in poor health condition, on the other hand least of them are in good health state; in the group of children with negative mycological findings the situation is reversed. Likewise, a connection is observed between yeast presence and repeated or long-term hospitalization: children with positive mycological findings are more frequently repeatedly or long-term hospitalized than those with negative findings. In the group of children with negative or incidental findings, the highest number had not been ill so far. A possible correlation is also seen between the yeast occurrence and the administration of broad-spectrum antibiotics; however, one must not forget that such antibiotics are usually given to patients in poor health.

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.

The following parts will contain characteristics of the species of other genera.

KOCKOVÁ-KRATOCHVÍLOVÁ A. (1964): Beitrag zur Ökologie der hefeartigen Mikroorganismen aus Pflanzenblüten.  Česká Mykologie 18(1): 29-35   (published: 25th January, 1964)
  abstract   A total of 213 yeast-like microorganisms were isolated from flower samples representing 25 species. These isolates formed 35.6% of all tested samples. The study used simplified identification methods based on fermentation types and showed correlations between plant families and microbial presence. Most yeast species found were non-spore forming.
