'''Lymphocytic - plasmacytic enteritis (LPE)''' is the most common form of [[Inflammatory Bowel Disease|Inflammatory Bowel Disease]] (IBD). As its name suggests, the predominant cell type in the intestinal mucosa is [[Lymphocytes - Introduction|'''lymphocytes''']] and '''plasma cells'''. Enteric parasites, bacteria in dogs and [[Toxoplasma|''Toxoplasma'']] in cats have been reported to associated with LPE. This disorder in cats have also been shown to associate with concurrent disease of the pancreas and liver such as [[Pancreatitis - Dog and Cat|pancreatitis]], [[Cholangitis|cholangitis]] and [[Hepatic Lipidosis|hepatic lipidosis]]. LPE is believed to be caused by an abnormal [[Regional Lymphoid Tissue - Anatomy & Physiology|mucosal associated lymphoid tissue (MALT)]] response to luminal bacterial, dietary or self-antigens. | '''Lymphocytic - plasmacytic enteritis (LPE)''' is the most common form of [[Inflammatory Bowel Disease|Inflammatory Bowel Disease]] (IBD).
