Peripheral blood eosinophilia and elevated serum IgE are usual but not universal. The damage to the gastrointestinal tract wall is caused by eosinophilic infiltration and degranulation. [15] As a part of host defense mechanism, eosinophils are normally present in gastrointestinal mucosa, though the finding in deeper tissue is almost always ...
After having excluded other diseases that can lead to vomiting, diarrhea, and abdominal pain in dogs, intestinal biopsies are often performed to investigate what kind of inflammation is occurring (lymphoplasmacytic, eosinophilic, or granulomatous). In dogs, low levels of cobalamin in the blood have been shown to be a risk factor for negative ...
Human intestinal spirochetosis, often called just intestinal spirochetosis when the human context is implicit, is an infection of the colonic-type mucosa with certain species of spirochetal bacteria. Similar infections sometimes occur in pigs, dogs, and birds; porcine intestinal spirochaetosis is an economically important disease of livestock.
Crohn's disease – also known as regional enteritis, it can occur along any surface of the gastrointestinal tract. The most common location for Crohn's disease to manifest, with or without the involvement of the colon or other parts of the GI tract, is in the terminal ileum (the final segment of the small intestine).

Several factors may influence the development of the disease, such as local colonic ischemia, fecal stasis, or mucosal prolapse. SCAD shares some features with inflammatory bowel disease, including the increase of tumor necrosis factor (TNF) alpha during active disease, and decrease in TNF during health improvement. The pathogenesis of SCAD ...
There is an increased risk of infection associated with amount of time spent outdoors, a larger roaming space accessed by the dog, and increasing age. [ 19 ] Cryptococcosis * is a fungal disease caused by Cryptococcus neoformans that affects both dogs and humans.
CCL28 has also been implicated in the migration of IgA-expressing cells to the mammary gland, [9] salivary gland, intestine [10] and other mucosal tissues. [11] It has also been shown as a potential antimicrobial agent effective against certain pathogens, such as Gram negative and Gram positive bacteria and the fungus Candida albicans .
Eosinophils usually account for less than 7% of the circulating leukocytes. [1] A marked increase in non-blood tissue eosinophil count noticed upon histopathologic examination is diagnostic for tissue eosinophilia. [2] Several causes are known, with the most common being some form of allergic reaction or parasitic infection.
