Resumen

Guillain-Barre syndrome is an autoimmune disease that provokes neural illness causing acute paralysis neuropathy. This syndrome appears after some bacterial infections produced by Campylobacter jejuni, Streptococcus pyogenes, S. pneumoniae, Haemophilus influenciae, E. coli and current studies showed the appears of this syndrome after SARS-CoV-2 infection. In this study, a in silico analysis was carry out in which to determinate bacterial epitopes than produce the molecule mimicry phenomena and that can produce the immune system activation against this epitope. A conserved amino acid sequence has been encountered with the highest probability to activate the immune system against this bacterial epitope, human gliomedin and ryanodine 3 type receptor. More studies needed to demonstrate in vivo the molecular mimicry in Guillain-Barre syndrome patients.
