MOUBASHER A.H., ABDEL-SATER M.A., SOLIMAN Z.S.M. (2018): Diversity of yeasts and filamentous fungi in mud from hypersaline and freshwater bodies in Egypt.   [fungal diversity, alkalinity, Wadi El-Natrun, lakes, Ibrahimia Canal, River Nile, molecular characterisation, ITS]  Czech Mycology 70(1): 1-32   (published: 26th January, 2018)
  abstract   The diversity of yeasts and filamentous fungi in muds from hypersaline alkaline lakes of Wadi ElNatrun and fresh water of the Nile River and Ibrahimia Canal was evaluated. The mean pH of saline water mud was 9.21, but fresh water mud registered 8.07. A total of 193 species (two varieties were distinguished in two of them) belonging to 67 genera were recovered from both muds investigated on DRBC (55 genera, 164 species), DG18 (36 genera, 117 species) and MY50G (23 genera, 76 species) media. From these, 17 species assigned to 12 genera were yeasts and 176 species and 2 varieties assigned to 55 genera were filamentous fungi. The highest numbers of fungal propagules were recovered on DRBC from freshwater mud, while the lowest on MY50G from saline water mud. Yeasts constituted a small proportion of all propagules from the two mud types on all three media, whereas filamentous fungi were the major component. However, freshwater mud samples yielded higher numbers of yeast genera and species using all three media. Candida was common in freshwater mud and rare in saline water mud, while Meyerozyma and Rhodotorula were infrequent in both muds. The remaining yeast species were recovered from freshwater mud only. Aspergillus (46 species) was the most common genus of filamentous fungi encountered in all samples, ranging in frequency from 39.82% to 96.62%; A. terreus, A. flavipes and A. niger dominated in both types of mud. Cladosporium (9 species), Fusarium (8 species), Penicillium (18 species) and Scopulariopsis (7 species) were encountered in both types of mud. Notably, 47 filamentous species were isolated only on the media with lower water activity (DG18, MY50G).

KHAN M.R., SAHA M.L., ANISUZZAMAN M., SLÁVIKOVÁ E. (2002): Yeasts isolated from the lakes of Dhanmondi and Ramna, Bangladesh.   [yeast community, occurrence, lake water, Bangladesh]  Czech Mycology 53(3): 223-228   (published: 10th January, 2002)
  abstract   The occurrence of yeasts in the water of two lakes located in Dhaka City over a period from September to December 1999 was investigated. The number of yeasts of lake Dhanmondi and Ramna ranged from 9.5X10⁴ to 35X10⁴ and 2.3X10⁴ to 11X10⁴CFU/l, respectively.The isolated yeast strains belonged to 5 species: Saccharomyces cerevisiae, Rhodotorula glutinis, Rhodotorula mucilaginosa, Debaryomyces hansenii var. fabryi and C and ida suecica. The maximum number of yeasts was found to be 3 times higher in the water samples of Dhanmondi lake than that of Ramna lake. The higher number of yeasts was correlated with the temperature of the water and with pH values.

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.

Five new combinations are proposed: Allophylaria filicum, A. campanuliformis, Calycellina lunispora, Conchatium durum, and Lachnum pubescens. Each taxon is provided with microscopic and macroscopic characteristics, typification, and detailed locality data.

KOCKOVÁ-KRATOCHVÍLOVÁ A., SLÁVIKOVÁ E., KOVAČOVSKÁ R., WAI YIN MOK (1988): Unusually occurring yeast-like organisms isolated from the equatorial locality in the basin of the river Amazon.  Česká Mykologie 42(3): 170-175   (published: 12th August, 1988)
  abstract   The paper shows the results of identification of unusually occurring yeast-like organisms isolated from the basin of the river Amazon near the equator. In addition to commonly known species of the genus Candida (e.g. C. albicans, C. tropicalis, C. guilliermondii, C. parapsilosis), species difficult to classify using standard keys were isolated from soil, human saliva, scalp, skin and amphibian tissues. Candida species comprised 75%, Trichosporon 19.5%, and sporogenic yeasts 5.5% of isolates. Most isolates were saprophytes, but pathogenic potential under specific climatic and physiological conditions cannot be excluded.

KOCKOVÁ-KRATOCHVÍLOVÁ A., SLÁVIKOVÁ E., KOVAČOVSKÁ R. (1988): Yeasts isolated from fruitbodies of mushrooms of the Lowland of Záhorie (Slovakia).  Česká Mykologie 42(2): 114-121   (published: 10th May, 1988)
  abstract   In 1984 yeasts were isolated from the surface of mushroom fruitbodies collected on the Lowland of Záhorie. Thirty-nine strains were isolated from 95 samples, 24 from fruitbodies and 15 from their environment. Similarities in physiological properties of repeatedly isolated strains from certain genera of forest fungi were studied. The species variability had unequal distribution, but sometimes identical species were found repeatedly on the same host genera.

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.

FRAGNER P. (1978): Yeasts in human material in our country and their differentiation. Part II.  Česká Mykologie 32(3): 129-143   (published: 15th August, 1978)

Macroscopic and microscopic appearance of the cultures, auxanograms, zymograms, growth at 37 °C, data on the pathogenicity for humans and animals as well as those on the origin of the cultures, etc. are presented. The following parts will contain characteristics of the species of other genera.

Abstracts of papers delivered at the 6th Conference of Czechoslovak mycologists held at Pezinok, 19.-23. September 1977.  Česká Mykologie 32(2): 99-122   (published: 1978)
  abstract   Tradice mezinárodních mykologických kongresů není stará. První byl v roce 1971 v anglickém Exeteru. K vrcholným vědeckým setkáním tohoto typu nelze přiřazovat již delší dobu pořádané Sjezdy evropských mykologů. Druhý mezinárodní mykologický kongres se konal ve dnech 27. VIII. až 3. IX. 1977 v prostorách University of South Florida v Tampě. Zúčastnilo se ho více než 1200 specialistů ze 43 zemí.
