Estimation of seroprevalence of Avian Encephalomyelitis in different parts of India

Surajit Baksi


An Avian Encephalomyelitis (AE) is a viral disease of young chicken. Hepatovirus of Picornaviridae family
is responsible for the disease, causing central nervous system signs. It is highly prevalent worldwide causing mortality up to 65%. Prevalence study of AE in broiler breeders was undertaken in various states
of India in the present research. Its occurrence was found in almost every region (average 10.3%) and it had affected egg production and affected the farms economically. The Highest prevalence of the disease was found in Telangana state (14.9%) followed by Madhya Pradesh (12.5%) and Haryana (11.1%). Age wise seroprevalence was also studied in the research, where it was found that birds aging 30-45 weeks were highly prone to the disease (25%). Effect of seasons was also investigated on the occurrence of AE,
in which it was revealed that 21% of the birds were infected with AE during the monsoon
