Antibodies against different Mycobacterium avium subspecies paratuberculosis (MAP), Epstein–Barr virus (EBV), and human homologue peptides including myelin basic protein (MBP) have been detected in the cerebrospinal fluid (CSF) of Italian patients with MS during the relapse phase [5], which indicates a role of the bacterium or virus in enhancing inflammation through a molecular mimicry mechanism [6]. This evidence concerns the gene MBP and myeloid sarcoma.
