<< In the light of recent studies showing the presence of 
spirochetes in the brains of Alzheimer’s disease (AD) patients, we have 
studied (post mortem) the hippocampus region in the brains of similarly 
affected AD patients utilizing both pathology and immunohistochemistry. 
Our findings demonstrate that the plaques, which are characteristically found in AD brains, reveal the presence of biofilms. These biofilms are undoubtedly made by the spirochetes present there; further, we have also found that the biofilms co-localize with the β amyloid that is a signature finding in the disease.

 Also, we have shown activation of Toll-like receptor 2 in the same 
areas. We postulate this is related to the disease because this innate 
immune system molecule cannot penetrate the biofilm to destroy the 
spirochetes present there, so, in as much as it is activated, it 
destroys the surrounding tissue instead. We compare this destruction to 
that which is caused by activation of the adaptive immune system, which 
leads to much more severe devastation, much more rapidly.>>
