Disease investigation on morbidity and mortality in cattle and buffaloes in two villages of Bareilly district of Uttar Pradesh was carried out in the month of June 2010. Common symptoms were off feed, low intake of water, dark faeces and death after suffering for 15-20 days. On clinical examinations, affected animals showed normal rectal temperature. In two necropsied buffaloes, the body cavities contained large amount of straw colored fluid mixed with fibrin flakes. Liver was found severely affected with hemorrhagic tracts and perforations with immature flukes in the pool of blood in hepatic parenchyma. The migratory haemorrhagic tracts were full of necrotic debris, cellular and haemorrhagic mass. Mononuclear cell reaction was observed along the side of necrotic haemorrhagic tracts. Occasionally these were encircled by proliferating connective tissue infiltrated by mononuclear cells. Hundreds of immature flukes recovered after teasing of liver were identified as Fasciola gigantica of about 8 weeks age but faecal examination showed F. gigantica eggs only in two buffaloes and amphistome eggs in all animals. Blood examination revealed anaemia and increased eosinophil count (9-38%). On microbiological examinations, no pathogenic organism could be isolated from the blood samples of the affected animals. On the basis of symptoms, post-mortem findings and laboratory examinations, the disease could be diagnosed as acute fasciolosis due to immature F.gigantica infection.
