KOLAŘÍK M., SLÁVIKOVÁ E., PAŽOUTOVÁ S. (2006): The taxonomic and ecological characterisation of the clinically important heterobasiodiomycete Fugomyces cyanescens and its association with bark beetles. [Fugomyces cyanescens, Microstromatales, fungi associated with bark beetles, rDNA phylogeny] Czech Mycology 58(1-2): 81-98 (published: 10th August, 2006)
abstract
Anamorphic heterobasidiomycete, taxonomically highly related or identical with Fugomyces cyanescens (Basidiomycota: Microstromatales), formerly known mostly from the clinical material, was frequently found in association with nine phloemophagous bark beetles at eleven localities in Hungary, Bulgaria and in the Mediterranean. The isolates were identified using morphological characteristics, its physiological profile and rDNA sequences and compared with the ex-type strain. The phylogeny was studied based on LSU and ITS-rDNA analysis. The morphology and ecology of the species is discussed in relation to related taxa which occur primarily on plants (phylloplane saprobes, parasitism), but sporadically also on clinical material obtained mostly from immuno-compromised patients.
SLÁVIKOVÁ E., VADKERTIOVÁ R. (2003): The occurrence of yeasts in grass-grown soils. [yeast community, totalyeast counts, Slovakia, grass-grown soil] Czech Mycology 54(3-4): 239-247 (published: 23rd May, 2003)
abstract
One hundred and fifty six yeast strains were isolated from 160 grass-grown soil samples collected in four different localities in Bratislava, Slovakia. The collection of soil took place in March, May, August, and October. Cryptococcus laurentii, C. albidus, Cyst of ilobasidium capitatum, Sporobolomyces salmonicolor, and Trichosporon cutaneum were the most frequently isolated species from the samples taken in the unpolluted localities Rusovce and Dúbravka. These species represented 92.1 % of totalyeast counts found in these soil samples. Cryptococcus laurentii, C. albidus, Cystofilobasidium capitatum, Debaryomyces castellii, and Rhodotorula glutinis were the most frequently isolated species from the samples taken in the polluted localities Polianky and Mlýnská Dolina. These species represented 93.3 % of total yeast counts there . Yeast densities ranged from 400 to 80.000CFU/g soil. We found that yeasts occurred unevenly in soils during the year. The lowest average number of yeasts was found in August and the highest one in May.
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 anumber 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, Candidaand Cryptococcus species occurred most frequently. The yeast populations of autumn and summer samples are compared.The total yeast count was 11 time shigher 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.

abstract
Investigations of yeasts isolated from 126 water samples show the occurrence o f 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 o f 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.
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.

abstract
Yeast and yeast-like microorganisms transferred by ants Formica rufa and ladybirds were isolated from some areas of lowlands of Záhorie. The group of the 21 strains of the yeasts, which were classified to several genera, is described. They were isolated from the surface of ants from some areas of lowlands Záhorie in association with two great genera Debaryomyces and Aureobasidium previously mentioned in our country.
SLÁVIKOVÁ E., KOCKOVÁ-KRATOCHVÍLOVÁ A. (1980): The yeasts in the genus Aureobasidium transferred by insects on the lowlands of Záhorie (Slovakia, ČSSR). Česká Mykologie 34(4): 199-207 (published: 1980)
abstract
43 strains of the genus Aureobasidium were isolated from the surface of ants Formica rufa and ladybirds from 6 areas of the lowlands of Záhorie. They were all identified as Aureobasidium pullulans (de Bary) Arnaud but they showed a great variability within the species. On the basis of this variability strains were tested in the similarity by the numerical method. Two subgroups were determined, which could be considered as ecotypes.
SLÁVIKOVÁ E., KOCKOVÁ-KRATOCHVÍLOVÁ A. (1980): The yeasts of the genus Debaryomyces transferred by insects on the lowlands of Záhorie. Česká Mykologie 34(1): 21-28 (published: 1980)
abstract
Fifty-three strains of the genus Debaryomyces were isolated from the surface of Formica rufa ants in nine areas of the Záhorie lowlands. All strains were identified as Debaryomyces cantarellii Capriotti, although they showed high intraspecific variability. Based on numerical taxonomy, two ecotypes were determined. Ants were collected near anthills, and yeast strains were isolated using wort agar. The study also reviews previous work on yeasts from plant material and insects.
