title: Rat strains differ in antibody response to natural Haemophilus species infection.
abstract: Antibody response to Haemophilus species in rat strains was monitored by enzyme-linked immunosorbent assay (ELISA) using antigens of two Haemophilus strains and a Pasteurella pneumotropica strain. Five rat strains from a breeding colony naturally infected by Haemophilus were significantly different in ELISA antibody activity and in the number of seropositive animals. BN and RP rats were (relatively) high and low responders, respectively and BUF, LEW and WAG rats were intermediate. In a second study, five rat strains were exposed to Haemophilus-infected rats, and, after six weeks, were also significantly different in ELISA antibody activity and in numbers of seropositive animals. Here, BN and LEW rats were (relatively) high and low responders, respectively, and BD IX, F344 and WKY rats were intermediate.
