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.

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.

KOCKOVÁ-KRATOCHVÍLOVÁ A., SLÁVIKOVÁ E., KOVAČOVSKÁ R., TOMANOVÁ E. (1989): Yeasts and yeast-like organisms in the fresh-water lake Rudava.  Česká Mykologie 43(4): 227-234   (published: 17th November, 1989)
  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. (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.

KOCKOVÁ-KRATOCHVÍLOVÁ A., ŠVORCOVÁ L., BREIEROVÁ E., DELGADO R. (1984): Taxonomic characteristics of yeasts isolated from bath facilities.  Česká Mykologie 38(1): 11-20   (published: 1984)
  abstract   This paper deals with the taxonomy and identification of yeasts and yeast-like organisms isolated from West-Bohemian bath facilities, as bath pools and their environments. The ecological, hygienical and sanitary aspects will be introduced elsewhere. This study follows the previous paper of Švorcová (1982).

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.

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.

FRAGNER P., PREISLER M. (1982): Incidence of yeasts in the mouth cavity of patients with parodontopathias.  Česká Mykologie 36(1): 52-56   (published: 1982)
  abstract   In patients suffering from some parodontopathies and diseases of the mouth cavity mucosa (most frequently parodontitis and gingivitis), yeasts were found in the mouth (on the tongue, teeth or gingivae) in 43.8% of cases, Candida albicans in 29.2% individuals. These percentages are strikingly lower than in the healthy population. Abundant or massive yeast findings (including Candida albicans) appeared only in parodontitis. The gingivae can sometimes be a wholly independent, isolated source. All yeast findings are given both qualitatively and quantitatively.

FRAGNER P., HEJZLAR J. (1981): Yeasts flora of the tonsills.  Česká Mykologie 35(4): 227-233   (published: 1981)
  abstract   Yeasts (including Candida albicans) in the mouth cavity (on the tongue and/or on the tonsills) were found in 60.0% individuals, Candida albicans (alone or in combination with other yeasts) in 43.5% individuals. In most cases the yeast flora of the tonsills was identical with that of the tongue, only in 5.8% it was species different. Tonsills as a probable yeast source (judging from a larger number of germs or different species than that on the tongue) were found in 6.8% individuals. Possible connections between yeast incidence and clinical picture of the tonsills and tongue, general health condition, administration of antibiotics and several other circumstances were followed.

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., 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.

FRAGNER P. (1978): Yeasts in human material in our country and their differentiation. Part IV.  Česká Mykologie 32(4): 235-245   (published: 1978)
  abstract   A diagnostic system for the identification of yeasts in human material is presented. Part IV of this series describes several species from the genera Torulopsis and Trichosporon. The article discusses limitations of the rapid method and current challenges in yeast identification.
