^aThe panel contains 2 representatives (where possible) of disease-associated serotypes. Respiratory isolates were selected when no other systemic isolate was available.

^bStrains in bold were also used in cross-reactive ELISAs, the results of which are shown in Fig. 6.

^cNP, not present. If the protein had less than an 80% identity over 80% of the length, it was classified as not present.
