Poultry mucormycosis: inflammation of the ileocecal valve
The ileocecal valve are located , in birds, in traffic ileum and cecum at the beginning of the large intestine. Its histological structure shows the presence of mucous cells and lymphatic tissue.
Inflammation of this structure has been attributed to viral reactions, especially Newcastle virus , although most of it is due to infection by fungi of the family of Mucorales ( Mucor , Absidia and Rizhopus ) showing high tropism for the intestinal lymphatic tissue (Peyer’s patches and ileocecal valve ).
The rapid intestinal transit brings valvulitis , Immunosuppression (one of the functions of the lymphatic valvular tissue) and lack of growth for non- absorption of vitamin B12 ( one of the specific functions of valvular mucosa).
