abstract
A case of disseminated cryptococcosis was proved by histology and cultivation. Cryptococci in tissue were rather polymorphous: spherical (3–6.5 μm), a bit oval or conspicuously elongated (2.5–4.5 × 5–8.5 μm), dumbbell-, roll-, and rod-shaped (2–2.2 × 4.5–6 μm). Some of them had a weak capsule less than 1 μm in thickness. Cultivated colonies grew glossy and smooth as well as dull and rough. Crude preparations made from the fuzzy border of rough colonies showed a pseudomycelium up to 50 μm long. About 30 preceding Czechoslovak cases of cryptococcosis were reviewed starting from 1954. But one of them was akin in histology to the present case; in another one, there was a rudimentary pseudomycelium in tissue. Literature concerning an atypical shape of cryptococci was commented.

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.

abstract
The author discusses the taxonomic relationship between the jelly fungi Tremella and yeast-like fungi of the genus Cryptococcus. Evidence suggests that haploid yeast-like forms of Tremella resemble Cryptococcus and produce similar extracellular polysaccharides, implying a possible evolutionary connection.

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).
ABDEL-SATER M.A., MOUBASHER A.H., SOLIMAN Z.S.M. (2016): Diversity of filamentous and yeast fungi in soil of citrus and grapevine plantations in the Assiut region, Egypt. [Mycobiota, biodiversity, phenotypic and biochemical characterisation, ITS sequence, Coniochaeta canina, Aspergillus stella-maris] Czech Mycology 68(2): 183-214 (published: 20th December, 2016)
abstract
An extensive survey of soil mycobiota on citrus and grapevine plantations in Sahel-Saleem City, Assiut Governorate, Egypt was carried out using the dilution-plate method and 2 isolation media at 25 °C. Sixty-four genera and 195 species of filamentous fungi and 10 genera and 13 species of yeasts were recovered. A higher diversity (number of genera and species) and gross total counts were recovered from citrus than from grapevine soil. The peak of filamentous fungi recovered from both soils was found to be in February. Aspergillus (45 species) was the most dominant genus; A. ochraceus predominated in citrus plantations, while A. niger and A. aculeatus in grapevine. The Penicillium count came second after Aspergillus in citrus (23 species) and after Aspergillus and Fusarium in grapevine (11 species).Penicillium citrinum, P. ochrochloron and P. olsonii were more common in citrus plantations, but they were replaced by P. oxalicum in grapevine soil. Fusarium (19 species) was represented in 88.9–100% of both soils on both media; F. solani predominated in both soils, while F. incarnatum came next in citrus, and F. babinda and F. oxysporum in grapevine. Humicola (3 species) with the dominant H. fuscoatra was recorded in 61.1–83.3% of soil of both plantations, while Talaromyces (with T. purpureogenus followed by T. pinophilus being the most common) was recorded in 83.3–100% on DRBC and 38.9–50% on DYM from the soil of plantations of both crops. Volutella (5 species) was common in citrus but missing from grapevine soil. The present study reveals that hyaline fungi predominated over dark-coloured ones. Yeasts comprised only minor proportions in both soils (maximum 0.5%). They showed their peak in the soil of citrus plantations in April and in grapevine in February. All species were recovered in one or two samples only. Diutina catenulata, Debaryomyces hansenii, Galactomyces (3 species), Hanseniaspora occidentalis, Kluyveromyces marxianus, Meyerozyma caribbica, and Schwanniomyces pseudopolymorphus were encountered in citrus only, while Cryptococcus laurentii, Pichia kudriavzevii, Meyerozyma guilliermondii and Rhodotorula sp. in grapevine only. Physiological and growth characteristics were obtained for most of the recovered yeasts.
PARVEEN S., WANI A.H., BHAT M.Y., KOKA J.A. (2016): Biological control of postharvest fungal rots of rosaceous fruits using microbial antagonists and plant extracts - a review. [biological control, postharvest diseases, microbial pesticides, rosaceous fruits] Czech Mycology 68(1): 41-66 (published: 1st February, 2016)
abstract
This article aims to give a comprehensive review on the use of microbial antagonists (fungi and bacteria), botanicals and compost extracts as biocontrol agents against different pathogenic fungi causing postharvest fungal rots in rosaceous fruits which shows that they can play an important role in the biomanagement of fungi causing rot diseases. Plant extracts reported in the literature against pathogenic fungi indicate that they can act as a good biological resource for producing safe biofungicides. However most of the work has been done under experimental conditions rather than field conditions. There is still a need for research to develop suitable formulations of biofungicides from these microbial biocontrol agents and plant extracts. The review reveals that extensive ecological research is also required in order to achieve optimum utilisation of biological resources to manage various postharvest diseases of fruits.

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.

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.

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
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.

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.

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.

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.

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., MÚČKA V. (1969): Experiments on the separation and identification of „Rubronigrin“. Česká Mykologie 23(2): 127-128 (published: 1969)
abstract
The substance which arises in cultivating mediums by means of the cultivating of Trichophyton rubrum var. nigricans (Fragner 1966) and which has an antibiotic effect on Cryptococcus (Fragner 1965) is not uniform. It is possible to release a basic gas by fast alkalising and warming of the older cultivating medium, which have pH value over 7 owing to the growth of T. rubrum var. nigricans. We determined in this gas dimethylamine by paper and gas chromatography and ammonia by the former of the two methods. The synthetic pure dimethylamine hydrochloride had an antibiotic effect. Our previous (Fragner and Múčka 1966) concentrates obtained by means of distillation were polluted by acrolein arising during dry distillation of glucose from cultivating medium. In younger cultivating mediums with pH ranging from 5.5 to 6.5 there arises — owing to the growth of T. rubrum (with a sharp maximum) — another very unstable substance with antibiotic effect, which we call at the time being “rubronigrin”.

abstract
A new variety of Epidermophyton floccosum is described. The cultures are characterized by a dark brown pigment staining the undersurface and medium. They show antibiotic activity against Torulopsis globosa and Cryptococcus diffluens.
FRAGNER P., KVIČERA J. (1968): Candida albicans non-forming chlamydospores. Česká Mykologie 22(2): 112-113 (published: 1968)
abstract
In examining the vaginal candidoses of prostitutes and suspected prostitutes, the authors isolated Candida albicans strains that did not form chlamydospores. The clinical pictures generally did not correspond to typical candidosis, and the animal experiments showed reduced pathogenicity.

abstract
New localities of Melanogaster tuberiformis Corda were found in Central Bohemia, expanding its known distribution from only one previous record. The fungus was located near Klánovice and Konětopy in habitats with Molinia coerulea, Populus tremula, Betula, and Frangula alnus.
FRÁGNER P. (1966): Trichophyton rubrum (Cast.) Sabouraud var. nigricans var. nova. Česká Mykologie 20(1): 27-28 (published: 1966)
abstract
Trichophyton rubrum (Cast.) Sabouraud var. nigricans var. nova differs from the typical form by producing a dark brown pigment and an antibiotic effective against Cryptococcus. Cultures were obtained from diseased nails and skin. The fungus shows no significant microscopic differences from the typical form.

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.
