Differences in the equine faecal microbiota between horses presenting to a tertiary referral hospital for colic compared with an elective surgical procedure.

Changes in bacterial populations in the faecal microbiota of horses presenting for colic observed in this study concurs with previous studies in veterinary and human patients with gastrointestinal disease. Future studies focusing on different causes of colic, chronic or recurrent disease, and the association with histological changes within the intestine are needed.
