About Disease

Under natural conditions, lymphoid leukosis has been the most common form of the leukosis/sarcoma group of diseases seen in chicken flocks, although in the 1990s myeloid leukosis become prevalent in meat-type chickens.  ALV viruses have similar physical and molecular characteristics and share a common group-specific antigen (p27). Detection of the major antigen (p27) present in the core of leukosis/sarcoma viruses forms the basis of several diagnostic tests.

Lymphoid leukosis occurs naturally only in chickens. Tumor mortality commonly accounts for ~1%–2% of birds, with occasional losses of ≥20%. Subclinical infection, to which most flocks are subject, decreases several important performance traits, including egg production and quality. Infection can occur horizontally from bird to bird by direct or indirect contact, or vertically from an infected hen to her eggs as virus is shed into the albumin of the egg.
