Table 2 Mean x- fold change of IgM + B ACC at days post aMPV vaccination a in HG and TC

From: Development of vaccine-induced immunity against TRT in turkeys depends remarkably on the level of maternal antibodies and the age of birds on the day of vaccination

  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).
