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.

PANCHAL S., MURALI T.S., SURYANARAYANAN T.S., SANYAL K. (2022): Hypersaline fungi as a source of potentially active metabolites against pathogenic Candida species.   [antifungal, bioprospecting, filamentous fungi, extremotolerant, hypersaline environment.]  Czech Mycology 74(1): 93-101   (published: 22nd April, 2022)
  abstract   Opportunistic and nosocomial human infections by various Candida species are of serious global health concern especially due to the spread of drug resistant strains and lack of treatment options. One of the main problems of bioprospecting for novel antimycotics is the rediscovery of already known molecules. To reduce the chances of such rediscoveries, one option is to search for unique metabolites from microbes of less studied and extreme habitats. Thirty-five fungal strains were isolated from solar salterns and the methanolic extracts of their culture supernatants were tested for the inhibition of human-pathogenic Candida albicans, C. dubliniensis, C. glabrata, C. lusitaniae, C. tropicalis, and two clinical isolates of C. auris. Of the fungi screened, two, viz. Curvularia nodosa and Fusarium cf. foetens, showed significant growth inhibition of all the Candida species. Although the effective molecules were not identified in this preliminary screening, it highlights the importance of bioprospecting fungi from extreme environments which have been neglected in the search for novel antibiotics.

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).

The aim of the colloquium was to provide a platform for a broad discussion on experimental mycology in all branches of basic and applied research. 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. Abstracts of the contributions are given here.

Colloquium "Fungi as Model Organisms in Research and Biotechnology", Olomouc, September 14th, 1999.  Czech Mycology 52(2): 139-178   (published: 20th April, 2000)
  abstract   The colloquium was organized by the joint Commission for Experimental Mycology of the Czechoslovak Microbiological Society and the Czech Scientific Society for Mycology. 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: phytopathology, biotechnology and ecology, physiology and biochemistry, and medical mycology. Each topic was opened with a plenary lecture (30 min.), followed by short communications (10 min.) and accompanied by poster presentations. Besides four plenary lectures, 15 short communications and 21 posters were presented. In total 38 researchers took part in the colloquium, at who discussed various questions of importance for experimental mycology until late in the evening. Abstracts of the contributions are given here.

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., 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., 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.

FRAGNER P. (1987): Microscopical diagnostic of onychomycoses.  Česká Mykologie 41(3): 153-161   (published: 10th August, 1987)
  abstract   Microscopical investigation in medical mycology is not less reliable than cultivation. Group classification is also precise enough in microscopical diagnosis of onychomycoses in KOH preparations with Parker ink (Parker Super Quink, blue-black, permanent). Detailed findings as well as distinguishing features in onychomycoses caused by yeasts, Scopulariopsis and dermatophytes are presented, accompanied by photographs.

FRAGNER P., KUNZOVÁ E. (1987): The problem of reliability of microscopic demonstration of yeasts in smears.  Česká Mykologie 41(1): 46-49   (published: 16th February, 1987)
  abstract   Production of milk-clotting enzymes was determined in 55 out of the 91 tested species of Basidiomycetes. The ratio between milk-clotting and proteolytic activity was assayed in 18 species. The most suitable ratio of the two activities was found in Phellinus chrysoloma and Kuehneromyces mutabilis.

FRAGNER P., SOUKUP K. (1985): Contemporary views on mycotic colpitis.  Česká Mykologie 39(2): 106-118   (published: 1985)
  abstract   During a mycological excursion in 1973 near Sadská (district Nymburk), Inocybe phaeoleuca Kühner was found in large numbers in sandy pine forest. According to mycologist J. Veselský, this was the first reliable record for Czechoslovakia. Description of macroscopic and microscopic features is included.

KOCKOVÁ-KRATOCHVÍLOVÁ A., RONALDO CONTRERAS O. (1985): Yeast-like organisms isolated form plant material on Cuba.  Česká Mykologie 39(1): 44-50   (published: 1985)
  abstract   In 1981, yeast-like organisms were for the first time studied from plant material in Cuba. From 80 samples, 62 isolates were obtained and categorized into six groups: smut-like organisms, apiculate yeasts, Candida and Torulopsis, Rhodotorula, Aureobasidium, and various others. All isolates grew at 42°C and produced a broad spectrum of hydrolytic enzymes.

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.

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.

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., 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.
