Immunogenicity of Haemophilus paragallinarutn strains belonging to Savvatasserotypes 1 and 2 was investigated. Eleven isolates tested could be divided into two immunotypes which correlated closely with serotype-specificity, one corresponding to strain221 of serotype 1 and the other to II-18 of 2. No cross-protection was observed betwesttthese immunotypes, even though in the hyper-immunized chickens. The bacterins preparedfrom serotype 2 strains never produced hemagglutination-inltibition antibody, but gaveprotection to the chickens against challenge-exposure with homologous type strains.Significantly individual variation in the agglutinin production was observed among tltechickens inoculated with single dose, which had enough protection. There was a tendencythat its protection rate was increased depending on the dosage of primary inoculatiort.
