  The stomach is not a preferred site for human parasitic infections. Cryptosporidium spp. has been found lining the gastric mucosa, which was virtually free of inflammation.
  Several cases of giardiasis have been reported, virtually all in stomachs with extensive atrophy and intestinal metaplasia.
  Because most patients also have H. pylori infection, it remains unclear whether Giardia intestinalis causes (...)

Patients typically present after age 40 years with a variable combination of cognitive impairment, pyramidal tetraparesis, peripheral neuropathy, and neurogenic bladder.

  Tetanus, also called lockjaw, is a medical condition characterized by a prolonged contraction of skeletal muscle fibers. The primary symptoms are caused by tetanospasmin, a neurotoxin produced by the Gram-positive, obligate anaerobic bacterium Clostridium tetani.

• ehrlichiosis
  2 February 2006

  Human ehrlichiosis is a tick-borne zoonosis caused by the newly described human hematotropic rickettsiae, Ehrlichia chaffeensis.
  The pathology and pathogenesis of human ehrlichiosis have not been adequately studied. Even with immunoperoxidase, the only previously known method to detect these organisms in tissue, ehrlichae are difficult or impossible to identify. This led many investigators to speculate that the pathogenesis of ehrlichiosis was not caused directly by the organism but could (...)
