  1. aIn all experiments vaccinated birds were inoculated oculonassaly with 104 TCID50 of live attenuated aMPV/A vaccine.
  2. b x-fold change = mean IgM+ B ACC of vaccinated group divided by mean IgM+B ACC of not vaccinated group.
  3. */**Significant difference in mean IgM+ B ACC of vaccinated birds in comparison to the not vaccinated group (T-test, *as p < 0,05 and **as p < 0,01).
