The serological prevalence of Marek’s disease (MD) virus in poultry in Southern India is reported. Samples (955) were collected from Andhra Pradesh, Kerala, Tamil Nadu and Karnataka from poultry farms and laboratories tested for Marek antigen and antibodies by Agar Gel Immuno-diffussion Test and Dot – ELISA. Virus: Marek’s vaccine Virus FC – 126 strain of HVT serotype 2 and 3 CVI 988 and field antigens from tumors, spleen, liver, skin and feather follicles and serum screened by AGID from broilers (80%) and broilers 20% from 35 farms of which 16 exhibited paralysis, tumors and enlarged spleens.
