If it's on your mind and it has to do with multiple sclerosis in any way, post it here.

Lyme disease diminishes and evades immune response

Lyme disease subverts immune system, prevents future protection
http://news.ucdavis.edu/search/news_det ... o?id=11254
The bacteria initially trigger a strong immune response in an infected animal, but findings from this study indicate that the bacteria soon cause structural abnormalities in “germinal centers” — sites in lymph nodes and other lymph tissues that are key to producing a long-term protective immune response.

For months after infection, those germinal centers fail to produce the specific cells — memory B cells and antibody-producing plasma cells — that are crucial for producing lasting immunity. In effect, the bacteria prevent the animal’s immune system from forming a “memory” of the invading bacteria and launching a protective immune response against future infections.
