Bacteriome profiles grouped by Blastocystis positivity independent of their geographic origin. Non-metric multidimensional scaling of Bray-Curtis dissimilarity index, displayed by Blastocystis positivity and nationality. Three dimensions were used for NMDS, as the third dimension improved the fit of ordination. Shape shows nationality; color shows PCR positivity for Blastocystis. Blastocystis positivity affects position of the samples along NMDS axis 2
