Fungi in Oral Rinse Samples

Fungi in Oral Rinse Samples

Title:
Overall distribution of fungi in oral rinse samples obtained from 20 healthy individuals

Description:
This figure showed the overall distribution of fungi in oral rinse samples obtained from 20 healthy individuals (the triangle and asterisk indicate samples containing 16 and 3 fungal genera, respectively). Among the culturable genera, 61 were represented by one species each, while 13 genera comprised between 2 to 6 different species; the total number of species identified were 101. The number of species in the oral cavity of each individual ranged between 9 and 23; more than 10 different genera with an abundance of >1% were detected in 70% (14/20) of the samples analyzed. When compared across all 20 individuals, four genera were present in the oral rinse of 10 or more study participants: Candida (15/20), Cladosporium (13/20), Aureobasidium (10/20), and organisms belonging to the family Saccharomycetales (10/20). Interestingly, a large percentage (36.1%) of fungi belonged to non-culturable category. The minimum number of genera identified in a sample (sample E3) was 3 (Candida, 15%; Saccharomycetales, 18.1%; unculturable, 62.3%), while the maximum number of genera identified was 16 in sample A2, which included Candida (5.5%), Dothediomycete (10.7%), Fusarium (4.1%), Aspergillus (3.9%), and Xylariales (7.7%). The non-culturable genera/family detected in the oral samples included Glomus, Leptosphaeriaceae, Ascomycete, Basidiomycete, Ectomycorrhiza, Endophytic fungi, and Glomeromycete.
