Plasma cell frequencies in one of the 3 isotypes, IgM, IgY or IgA in lung, spleen and blood at 14 days post challenge. Elispots analysis of the 4 groups, when lymphocytes isolated from spleens, blood and lungs 14 dpc exhibited no difference between groups, organs or isotype. Only in the lungs high number of IgY producing cell were found in the two HH groups while in the LL groups low IgY producing cells could be detected.
