However, in subjects with recent/exposed infections by C. jejuni anti-GM1 IgG and the heteromeric complexes GM:PS, GM1:GT1a, GM1:GD3, GM1:Sulfatide, and GD1a:GT1a were associated with GBS in the conditional logistic regression models adjusted for sex, upper respiratory infection or influenza four weeks before onset or the number of infections (S7 Table). This evidence concerns the gene PPP1R3A and respiratory tract infectious disorder.
