Study Arms:
- Cohort C: Blautix (Type: EXPERIMENTAL): Participants diagnosed with Irritable bowel syndrome subtype C (IBS-C) received two capsules of Blautix orally, twice daily for 8 weeks. Maximum daily dose of Blautix (strain of Blautia hydrogenotrophica) will be 10\^10 to10\^11 most probable number (MPN).
- Cohort C: Placebo (Type: PLACEBO_COMPARATOR): Participants diagnosed with IBS-C received two capsules of placebo matched to Blautix orally, twice daily for 8 weeks.
- Cohort D: Blautix (Type: EXPERIMENTAL): Participants diagnosed with Irritable bowel syndrome subtype D (IBS-D) received two capsules of Blautix orally, twice daily for 8 weeks. Maximum daily dose of Blautix (strain of Blautia hydrogenotrophica) will be 10\^10 to10\^11 MPN.
- Cohort D Placebo (Type: PLACEBO_COMPARATOR): Participants diagnosed with IBS-D received two capsules of placebo matched to Blautix orally, twice daily for 8 weeks.
