Isolation of chicken anemia agent with MDCC-MSB1 cells from chickens in the field.

An attempt was made to isolate chicken anemia agent (CAA) from chickens suffering from anemia in the field by using MDCC - MSB1 , which was an established cell line derived from Marek's disease lymphoma. When 99 chickens of 15 flocks were examined, CAA was isolated from 58 chickens of 12 flocks. The rate of CAA isolation with MDCC - MSB1 cells was almost the same as that determined by an in vivo method by chick inoculation. It was shown that CAA was more closely concerned with anemic diseases of chickens in the field than fowl adenoviruses.
