Immunology and Pathology: Poultry Immunology and Pathology

Immunomodulators like β-glucans have attracted considerable attention as potential alternatives to the prophylactic use of antibiotics. Despite increasing research, little is known about their regulatory influence on immune function in poultry. Two studies were conducted to evaluate the effects of a yeast-derived β-glucan (Auxoferm YGT) on gene expression of T helper cytokines in the intestine....

Immunology, Health, and Disease: Immunology I

Major histocompatibility complex (Mhc) genes produce significant effects on immune responses . In addition, genes outside the Mhc influence immunity . USDA inbred chicken lines 63 and 72, differ in immune characteristics including immune organ size, immunoglobulin levels, immune cell subset distribution, mitogen-induced lymphoproliferation as well as responses against Marek’s disease virus, Rou...

The pathological changes involved in the immunological lung diseases of the bronchiolar region are reviewed. Next, the possibility that BOOP and DPB, two diseases whose causes are presently unknown, are caused by immune responses, is discussed.
