aOnly the serotypes that presented at least 10 non-susceptible isolates are shown.bSignificant P-values after FDR correction are highlighted in bold.cOther serotypes found among PNSP: 6B (n = 8), non-typable (n = 7), 6A and 29 (n = 5, each), 23B and 24F (n = 3, each), 7C (n = 2), 1, 3, 4, 11A, 15B, 15F, 22F, 23A, 35A (n = 1, each).dNT – non typable.eOther serotypes found among ERP: 9V and 11A (n = 4, each), 3, 15B, 22F, 23A, 24F (n = 3, each), 6A (n = 2), 1, 7F, 8, 9N, 15F, 16F, 17F, 23B, 29, 33F and 35F (n = 1, each).
