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.

HROUDA P., KŘÍŽ M. (2024): Orthography of Pilatian names: establishing the correct epithets with regard to Latin and nomenclatural rules.   [Albert Pilát, code, genitive form, MycoBank, nomenclature, orthographic variant.]  Czech Mycology 76(2): 175-190   (published: 18th December, 2024)
  abstract   The contribution deals with the issue of specific or subspecific epithets published by various authors in different forms, alberti/albertii or pilati/pilatii, and currently mostly maintained with the termination -ii in official repositories for names, especially the MycoBank and Index Fungorum databases. A view into the protologues of each name dedicated to Albert Pilát clearly shows that different terminations have been applied in different periods, and that relevant recommendations of the International Code of Nomenclature have also evolved over time. The orthographic variants alberti and pilati are in principle correct, based on the Latinised form of Pilát’s full name. Thus the original names of the involved taxa are to be maintained or resurrected if such epithets were given in their protologues. However, names later formed with the epithets albertii or pilatii appear to be in accordance with the provisions in force at the time. For a complete view of the topic, some examples of seemingly similar epithets created in different ways are mentioned for comparison, and the issue of interpretation of relevant recommendations of the Code is discussed in general. Finally, different approaches to nomenclatural stability are stated as a matter to be resolved in the upcoming Madrid Code.

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).

VAHEDI-DARMIYAN M.E., JAHANI M., MIRZAEE M.R., ASGARI B. (2017): A noteworthy record of endophytic Quambalaria cyanescens from Punica granatum in Iran.   [endophyte, flower, pomegranate, Quambalariaceae.]  Czech Mycology 69(2): 113-123   (published: 26th July, 2017)
  abstract   During an investigation into endophytic fungi associated with pomegranate in the South Khorasan Province of Iran, 2015–2016, five isolates were recovered with the morphological and molecular characteristics of Quambalaria cyanescens. The present study is the first fully documented report of Q. cyanescens from Iran, providing insight into its geographic distribution and host range. Our study is also the first report of occurrence of Q. cyanescens as an endophyte in a member of the Lythraceae family.

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.

TALIGOOLA H.K., ISMAIL M.A., CHEBON S.K. (2011): Mycobiota and aflatoxins associated with imported rice grains stored in Uganda.   [rice grain, xerophilic fungi, nephrotoxigenic penicillia, Fusarium, aflatoxins]  Czech Mycology 63(1): 93-107   (published: 10th August, 2011)
  abstract   Milled rice grains imported into Uganda from Pakistan were investigated for natural contamination by fungi and aflatoxins. The direct plating method using five isolation media was used to enumerate and isolate the fungi during a 270-day storage period. Fungi were isolated and identified to species level and the percentage contamination levels were calculated. A total of 35 species belonging to 16 genera were recorded. The broadest species spectrum were found in the genera Aspergillus, Penicillium, Eurotium and Fusarium, which were represented by 11, 7, 4, and 3 species, respectively. Throughout the storage period, xerophilic fungi including Aspergillus candidus, Eurotium amstelodami and E. chevalieri were predominantly isolated. Species of the genus Penicillium (particularly P. pinophilum) and its teleomorph Talaromyces ranked second in predominance, while Aspergillus flavus, Fusarium spp. and other field fungi occurred only sporadically. Aflatoxins were recorded in rice samples during most storage periods with one sample recording 20–50 ppb. The moisture content increased in rice grains attaining values of over 14 % from the 180th day of storage onwards. A positive correlation was observed between moisture content and incidence of xerophiles, including A. candidus and E. amstelodami.

ISMAIL M.A., TALIGOOLA H.K., NAKAMYA R. (2008): Mycobiota associated with baby food products imported into Uganda with special reference to aflatoxigenic aspergilli and aflatoxins.   [mycobiota, aflatoxigenic aspergilli, aflatoxins, imported baby foods]  Czech Mycology 60(1): 75-89   (published: 4th July, 2008)
  abstract   Five baby food products imported into Uganda were collected from different shops and investigated for contamination by fungi and aflatoxins. Forty-two species belonging to 21 genera in addition to some unidentified fungi were recovered on dichloran rose bengal chloramphenicol agar. Cornflakes followed by Cerelac were the most heavily contaminated products while Heinz mixed cereal was the least. Cladosporium sphaerospermum, Fusarium tricinctum and Penicillium oxalicum were the most predominant fungi. On the other hand, using Aspergillus flavus/parasiticus agar, 34 % of the samples were positive for aflatoxigenic aspergilli. Aflatoxigenic aspergilli constituted 78.8 % of all aspergilli and 4.9 % of all contaminating fungi. Samples from all products were contaminated with aflatoxigenic aspergilli, but samples of Cerelac were the most, while those of Porridge oats were the least. Aflatoxin analysis of food samples revealed that 9 out of 13 analysed samples were contaminated with aflatoxins in the range of 1–10 ppb (6 samples) and 11–20 ppb (3 samples). Only samples of Cerelac were aflatoxin–free, although aflatoxigenic aspergilli were detected in some samples. It was noted that samples of Cerelac had the least moisture content compared to the other products. Contaminated foods constitute a health hazard to human consumption. These foods, especially those for babies, must therefore be examined at regular intervals in order to assess their hygienic quality.

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.

Colloquium "Fungi as Model Organisms in Research and Biotechnology - II", Olomouc, Czech Republic, September 5th–6th, 2002.  Czech Mycology 55(1-2): 103-149   (published: 23rd July, 2003)
  abstract   The colloquium was a continuation of a previous scientific meeting that took place in Olomouc in 1999 (Czech Mycology 52: 139-178, 2000). It was organised by the joint Commission for Experimental Mycology of the Czechoslovak Microbiological Society and the Czech Scientific Society for Mycology together with the Institute of Biology, Faculty of Medicine of Palacký University, Olomouc. 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: biochemistry, biotechnology and genetics of fungi; phytopathogenic fungi; fungi pathogenic to humans and animals; and mycology of food and mycotoxins. Each topic was opened with a plenary lecture (30 min.), followed by short communications (10 min.) and accompanied by poster presentations. Besides five plenary lectures, 20 short communications and 24 posters were presented. In total 42 researchers took part in the colloquium and discussed various topics important for the further direction of experimental mycology. Abstracts of the contributions are given here.

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 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.

VOLLEKOVÁ A. (1992): Microscopic and cultural proof of Malassezia furfur in skin scales.  Česká Mykologie 45(4): 164-171   (published: 21st May, 1992)
  abstract   Microscopically (KOH with Parker ink) and semiquantitatively culturally ("ZOT" medium), 750 samples of skin scales from different areas of the body surface of 665 subjects (with or without dermatoses) were investigated for Malassezia furfur. This lipophilic yeast was isolated mostly from the capillitium, face and trunk (72–90% of samples). A total of 81.4% of samples were positive for M. furfur (65.6% microscopically and 73.5% culturally). In 57.7% of cases the yeast was observed by both methods. The average cultural detection was higher in samples with more microscopically visible blastoconidia. The results of M. furfur cultivation were influenced by several factors (e.g., subject preparation, timing of sample inoculation, cultivation conditions).

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   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   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., MICHÁLKOVÁ B. (1982): Is there a professional hazard of yeast incidence in stomatologic personnel?  Česká Mykologie 36(4): 243-247   (published: 1982)
  abstract   In the oral cavity of stomatological personnel, yeast colonization was found in 46.0% and Candida albicans in 33.0% of individuals — less than in the general population. C. albicans was least frequent in female doctors (24.2%), more frequent in nurses (30.6%), and highest in technicians (45.2%). Nurses with C. albicans had worked an average of 12 years in the field, while those without the yeast had worked 23 years. Interestingly, C. albicans appeared more often in younger individuals, contrary to trends in the general population. The study concludes no professional colonization risk exists.

  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.

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.

  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.

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.
