Immunodetection of Helicobacter sp. and the associated expression of ABO blood group antigens in the gastric mucosa of captive and free-living New World primates in the Amazon region

摘要: The histo-blood group ABH antigens were first described in humans. These are only present on erythrocytes from great apes and humans, while more primitive animals they found tissues body fluids. mainly distributed exposed to the external environment potentially serve as ligands for pathogens or inhibitors of tissue connections. objective this paper was two-fold: (i) determine presence Helicobacter sp. gastric mucosa 16 captive 24 free-living New World monkeys (ii) evaluate histopathological alterations related bacterial infection associated expression tissue. Stomach 13 species monkey assessed using haematoxylin-eosin modified Gram staining (Hucker) methods. An immunohistochemical analysis revealed infectious bacteria that characteristic genus results demonstrate various might be naturally infected with there is an increased susceptibility infection. This study serves a comparative between human non-human primates indicates new Helicobacter.
