  • a Titers were measured by the direct agglutination technique.

  • b Penner serotype as given in the NCTC catalog. For Penner serotype 5, strain 12504 is hippurate positive and strain 12525 is hippurate negative.

  • c I, unabsorbed antiserum; II, absorbed antiserum if appropriate.

  • d NI, type not included in the LEP scheme because antisera were indistinguishable by direct agglutination: antiHS9 = antiHS38, antiHS11 = antiHS64, antiHS47 and antiHS54 = antiHS14, and antiHS65 = antiHS50.

  • e ANR, absorption not required for current clinical isolates; see text.
