Other significant, although less frequently identified, infectious agents in GBS patients include Epstein-Barr virus (EBV), Mycoplasma pneumoniae, and varicella-zoster virus. [37] An association between GBS and acute human immunodeficiency virus (HIV) infection also is well recognized. [8, 38, 39, 40, 41, 42]

Infections with Haemophilus influenzae, Borrelia burgdorferi, para-influenza virus type 1, influenza A virus, influenza B virus, adenovirus, and herpes simplex virus have been demonstrated in patients with GBS, although not more frequently than they have in controls. [43]
