Fig. 3From: Evaluation of humoral immune responses to enterotropic lentogenic VG/GA vaccine of Newcastle disease in commercial turkey poults (Meleagris gallopavo)HI titers at different specific time points after vaccinations. The antibody response against the VG/GA vaccine was determined by performing a standard haemagglutination inhibition assay (HI) using the VG/GA virus as antigen. HI titers were calculated as log2 value to express the titers of the highest reciprocal of the dilutionBack to article page
