ABSTRACT

 

H. Habibi, H. Nili, K. Asasi, S. Nazifi*, N. Mosleh, S. Firouzi.,  Acute phase responses in village chickens challenged by a wild Newcastle disease virus isolate (JF820294.1.), Onl J Vet Res., 17(10):571-577, 2013.  Acute phase proteins (APP) are synthesized in the liver during the acute phase response to trauma, infection, stress, neoplasia, inflammation and Newcastle disease. Three groups of 15 Day old chicks each were challenged with JF820294.1 virus, vaccinated then challenged with JF820294.1 or used as non-challenged, non-vaccinated controls. Serum was assayed for TNF-α, IFN-γ, haptoglobin, serum amyloid A, total, lipid-bound and protein-bound sialic acid by standard procedures. All parameters except haptoglobin showed significant differences from controls at different days post challenge. Results suggest that a thermostable I-2 vaccine in prevented mortality and reduced APP in chickens.

 

Key words: acute phase protein, village chicken, Newcastle disease
