subspecies (MAP) and Crohn's disease: the debate continues.

Crohn's disease (CD) in humans and Johne's disease (JD) in ruminants share numerous clinical and pathologic similarities. As subspecies (MAP) is known to fulfill Koch's postulates as the cause of JD, there has been considerable debate over the past century about whether MAP also plays a role in CD. With recent advances in MAP identification techniques, we can now demonstrate a higher presence of MAP in CD patients compared to the general population.

Phenotype and Natural History of Inflammatory Bowel Disease in Patients With Concomitant Eosinophilic Esophagitis.

Background: The co-occurrence of autoimmune diseases is well recognized. Though studies have suggested that eosinophilic esophagitis (EoE) is more common in patients with inflammatory bowel diseases (IBD), whether co-occurrence of EoE modifies natural history of IBD is unknown.

Methods: This was a retrospective case-control study at a referral center.
