title: Antigenic relationships between the serotypes of Pasteurella haemolytica demonstrable by enzyme-linked immunosorbent assay (ELISA).
abstract: Mice and rabbits were immunised with sodium salicylate extracts (SSE) prepared from each of 12 serotypes of Pasteurella haemolytica, and the antisera to each were used in cross-indirect haemagglutination (IHA) tests and cross-enzyme-linked immunosorbent assays (ELISA) to study antigenic relationships between the serotypes. An indirect micro-ELISA demonstrated common antigenic relationships which were not apparent by IHA. Antisera from both species revealed considerable shared antigenicity between all the serotypes. Rabbit antisera presented clearer differences between the A biotypes on one hand and the T biotypes on the other, the T biotypes exhibiting much less cross-relatedness than that shown between the A serotypes.
