The bacterial intestinal microbiota plays major roles in human physiology and IBD. Recent studies have
been shown to characterise the faecal fungal microbiota in patients with IBD.
9, 10.
The IBDX research kits are an excellent tool to study fungal macrobiota dysbiosis in IBD. As shown in the figures below, two dominant fungal species microbiata are associated with IBD. Saccharmoyces cerevisiae (IBDX gASCA) and Candida albicans.
C. albicans glycans are distributed into 40% glucans (polymers of [1]alpha-1,3 glucose [i.e. ALCA] and -1,6-glucose [i.e. Anti-L]), 2 to 4% chitin [i.e. ACCA/Anti-C], and 30% mannose chains [i.e. AMCA].
Fungal microbiome associated with IBD. Differences in abundance are shown for the fungal taxa detected using ITS2 sequencing and a multivariate statistical approach
Absolute C. albicans abundance in the faecal microbiota quantified using qRT-PCR (mean±SEM).
Relative proportion of Candida albicans calculated by subtracting the log number of C. albicans from the log number of all fungi.
