Description: Gut bacteria with significant seasonal effects on their relative abundance, compared to autumn, after controlling for diet and subject effects.
Abundance in Group 1: increased abundance in Groups B (consumed both Hawaijar and Dahi), C (consumed Hawaijar, not Dahi), and D (consumed Dahi, not Hawaijar)
