can rmsf cause vasculitis in the brain
These bacteria cause vasculitis, the medical term for inflammation of blood vessel walls. The presence of the bacteria and the resulting vasculitis can cause swelling of blood vessel walls, bleeding, shock, formation of blood clots, organ damage and circulatory collapse. The organs most commonly affected by RMSF are the heart, kidneys and skin, but damage to all organs, including the brain, is possible.
