Lower antibody titres were produced in infected animals than in uninfected animals. Five days post infection, control and infected animals were inoculated with recombinant Newcastle disease virus (LaSota strain). On the day of vaccination, as well as 14 days post vaccination, serum samples were collected from both experimental groups. Circulating NDV-specific antibodies were assessed by enzyme-linked immunosorbent assay (ELISA). A The MFI of MHC-II molecule expression in monocytes and MHC-II⁺MRC1L-B⁻ cells isolated from infected and uninfected animals is shown in Figure 1D. B ELISA results are presented as the S/P ratios. Significant differences are indicated by *p = 0.0379. The results are expressed as the mean ± standard deviation values.
