Fungal allergens
Published in Richard F. Lockey, Dennis K. Ledford, Allergens and Allergen Immunotherapy, 2020

Candida albicans belongs to the fungal class Saccharomycetes, order Saccharomycetales, and family Saccharomycetaceae, which include yeasts that reproduce by budding. Another member of the same family, Saccharomyces cerevisiae, is perhaps the most economically important fungus and has served as a model eukaryotic organism for molecular and cell biologists. S. cerevisiae enolase has been identified as an important inhalant allergen associated with baker's asthma in occupational settings, with cross-reactivity to C. albicans enolase [160–162].
Oral Health

Fungi: As many as 85 different species of fungi have been found in the normal oral microbiota (Ghannoum et al. 2010). The most predominant genera were Candida, Cladosporidium, Aureobasidium, Saccharomycetales, Aspergillus, Fusarium, and Cryptococcus (Ghannoum et al. 2010). It is, however, uncertain if all detected species represented active colonization, or if airborne spores were also detected.
Debaryomyces
Published in Dongyou Liu, Handbook of Foodborne Diseases, 2018
The hemiascomycetes yeast genus Debaryomyces belongs to the family Debaryomycetaceae, order Saccharomycetales, class Saccharomycetes, subdivision Saccharomycotina (the budding yeasts), and division Ascomycota. It currently includes 18 valid species (i.e., D. coudertii, D. fabryi, D. gruetzii, D. hansenii, D. macquariensis, D. maramus, D. mycophilus, D. nepalensis, D. prosopidis, D. psychrosporus, D. robertsiae, D. singareniensis,8D. subglobosus, D. tyrocola, D. udenii, D. vietnamensis,9D. renaii,10 and D. vindobonensis) in addition to the Debaryomyces hansenii anamorph Candida famata and the D. subglobosus anamorph C. flareri (https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?id=4958).11
Role of IgA in the early-life establishment of the gut microbiota and immunity: Implications for constructing a healthy start
Published in Gut Microbes, 2021

Similar to gut virome, interactions among the bacterial microbiota, mycobiome, and gut immunity have been reported. Clusters IV and XIVa of Clostridia resist the colonization of Candida albicans via the hypoxia-inducible factor-1α-mediated generation of LL-37 in mice.42 The administration of anti-fungal agents exaggerated dextran sulfate sodium (DSS)-induced colitis and house dust mite-induced allergic airway disease, along with bacterial dysbiosis, including a decline in Bacteroides and Clostridium and an increase in Streptococcus.43 Unlike bacterial microbiota, fungal diversity changes moderately over time, with a slight increase in alpha-diversity while beta-diversity remains virtually unchanged.44 A transformation from Debaryomyces hansenii to Saccharomyces cerevisiae was evident in Saccharomycetales during the first year of life.44 Balanced mycobiota in adults mainly include Candida, Malassezia, and Saccharomyces.45
In vitro Candida albicans biofilm formation on different titanium surface topographies

The oral microbiome is reported to contain over 700 species and includes Gram-positive bacteria with genus such as Actinomyces, Bifidobacterium, Corynebacterium, Eubacterium, Lactobacillus, Propionibacterium, Pseudoramibacter, Rothia, and Gram-negative organisms with genus Campylobacter, Capnocytophaga, Desulfobacter, Desulfovibrio, Eikenella, Fusobacterium, Hemophilus, Leptotrichia, Prevotella, Selemonas, Simonsiella, Treponema, Wolinella. Non-bacterial species such as protozoa, viruses and fungi (mainly Candida, Cladosporium, Aureobasidium, Saccharomycetales, Aspergillus, Fusarium and Cryptococcus) are also present [6]. Some of these organisms are able to attach to the oral mucosa, tooth enamel or any inert surface placed in the oral cavity [7,8]. This includes implant surfaces where the microbial community can provoke the development of periodontal and peri-implant diseases [9,10].
Oral microbial diversity analysis among atrophic glossitis patients and healthy individuals
Published in Journal of Oral Microbiology, 2021
Hong Li, Jing Sun, Xiaoyan Wang, Jing Shi
For fungi, Saccharomycetales_unidentified_1 was the high relative abundance species at the genus in the atrophic glossitis and significant difference between two groups (Figure 2b, Figure 4b). The result showed that its relative abundance did not rise with the increasing of atrophic degree (Figure 8b). It seems that the increasing with the atrophic degree dose not promote overgrowth of Saccharomycetales_unidentified_1. However, the result showed that it was still the main genus in the atrophic glossitis group Figure 7 (c,d). Therefore, Saccharomycetales is a vital fungi for atrophic glossitis and may influence the progression of atrophic glossitis.
