From: Association between the ABO blood group and the human intestinal microbiota composition
RDA visualization of microbiota profile similarities and ABO blood group types. Each dot represents a single individual, taking into account all individual intensities measured in each PCR-DGGE group. Diamonds mark the calculated data centre points of the corresponding blood groups. P-value marks the statistical significance of the differences between the blood groups from ANOVA-like permutation test. Dot colours for the ABO blood groups are as follows: A = red, B = blue, AB = green and O = black. a) PCR.-DGGE with Bacteroides fragilis (BFRA) primers, b) Lactobacillus (LACT) primers and c) Bifidobacterium (BIFI).
