A. V. Purushothaman and A. Rajan
During the course of a systematic investigation into the hepatic disorders in cattle, 1025 livers of cattle and buffaloes were examined. Amphistomiasis (7), schistosomiasis (2) and fascioliasis (14) were encountered. Amphistomes were recorded in the liver of cattle for the first time. The parasites were identified as P. cervi, F. gigantica and S. spindale. Unusual cases of concommittant infection with liver flukes and schistosomes (2) and liver flukes and amphistomes (2}were also encountered. The pathological features of these conditions have been described in detail. Both Amphistomes and Fasciola caused chronic cholangitis. Chondroid and osseus metaplasia were encountered in some cases of fascioliasis. In schistosomiasis, phlebitis and multiple granuloma were the characteristic features.
