Hydropericardium syndrome (HPS) is as very recent and mysterious disease affecting chicken. This disease was first reported in growing chicks in Pakistan. It was mainly seen in commercial broiler chicks aged 3-5 weeks and was characterised by hydropericardium filled with straw coloured fluid in the pericardial sac. No clinical signs except sudden death upto 60-70% could be observed. In India, the disease was first noticed in the poultry belt of Jammu in April 1994. Later it spread to the rest of the country. In Tamil Nadu, the disease was first recorded in Palladam which is considered as broliler belt of Tamil Nadu. In India, the syndrome was called "leechi disease" because the heart with hydropericardium resembled shelled leechifruit. Adenovirus was isolated from the liver of chickens affected with HPS. The serotype of the adenovirus isolated from the chickens with HPS was type 4.
