| Popis: | In this study, the status of T cell-dependent cytokine gene expressions in the acute phase (3-day post-infection and 5-day post-infection) of infection with vaccine virus strains of New castle disease virus (NDV) (R2B and Lasota), Avian infectious bronchitis virus (AIBV) (Massachusetts H120), and Infectious Bursal Disease virus (IBDV) in SPF chicken of seven day age was evaluated. The birds were divided into four groups, each having six birds. Each group of birds was inoculated with the prescribed dose of different vaccines at 7 days of age. Blood was collected before inoculation (uninfected), at the 3rd and 5th day post-inoculation. Presence of virus in peripheral blood confirmed by real-time reverse-transcription PCR assay and quantitation of cytokine was performed in peripheral blood by real time PCR assay. It was observed that the infection with different vaccine strains of viruses in poultry modulates cytokine expression in order to elicit antiviral immune responses. AIBV and NDV viruses markedly up-regulate IL- 2, IL-12, p40, IL-4, IL-5, and IL-13 whereas, IBDV induces prolonged up-regulation of IFN-γ, IL-10 genes. |
