Abstract:
A survey on antibody against hemorrhagic enteritis virus was conducted by the agar-gel precipitation test among chicken flocks in Japan. The positive rate of individual serum samples increased with the advance in age of chickens. Ninety-one of 181 sera (50%) and 23 of 33 flocks (79%) were positive among chickens more than 181 days old.
