Immunomodulatory Effect of Vitamin C on Proinflammatory Cytokines Production in Ossimi Lambs () with Pneumonic Pasteurellosis.

In this study, we have investigated the impact of vitamin C on the production of pro-inflammatory cytokines (interleukin 1 β (IL-1 β), interleukin 6 (IL-6), interleukin 12p40 (IL-12p40), interferon gamma (IFNγ), and tumor necrosis factor alpha (TNF-α)) in lambs naturally infected by pneumonic pasteurellosis. Of 37 lambs, 18 lambs were identified to have pneumonic pasteurellosis and randomly allocated into two equal groups. Single subcutaneous dose of tulathromycine alone (2.
