A study on the pathogenesis of Trypanosoma evawi was carried out in 5 buffalo calves and 5 buffalo adults, 6 Holstein-Friesian calves and 6 Holstein-Friesian adults, and 6 Ongole calves and 6 Ongole adults, each ofwhich was divided into 3 infected and 2 uninfected buffalo calves and adults, and 3 infected and 3 uninfected calves and adults of Holstein Friesians and Ongoles. None of infected animals showed acute clinical signs along the course of the observation period, however roughness of the hair and skin, emaciation, weakness and loss of weight gains were the common clinical signs. Clinical signs of calves were more severe than adults, and those of buffaloes were more severe than cattle . Gross pathological changes were not specific . The mortality rate was 2/3 in buffalo calves, 1/3 in Holstein-Friesian calves and 1/3 in Ongole calves . None of infected adults died of infection. Buffaloes had longer and higher parasitemia than Holstein-Friesians or Ongoles. Erythrocyte counts of infected animals decreased to lower levels than controls, however they fluctuated in the normal values . Haemoglobin and PCV values of infected animals were significantly lower than those of non-infected controls, and those of calves were more severe than adults, and those of buffaloes were more severe than cattle . Infections resulted in loss of weight gains which was the greatest in buffaloes then followed by Holstein-Frisians and finally Ongoles. Key words: Trypanosoma etnnsi, pathogenesis, buffalo, Holstein Friesian cattle, Ongole cattle

The aim of this study was to identify trematodes which utilise Lymnaea rubiginosa as the fast intermediate host. This study was conducted in irrigated rice fields in Bogor regency and at Surade, West Java. A total of 3,253 L rubiginosa were collected from irrigated rice fields from Bogor regency and 2,875 from Surade. The results showed that cercariae of echinostomes, strigeid, Trichobilharzia sp. and Xiphidiocercariae were found in snails from Bogor regency, whereas Xiphidiocereariae and cereariae of Fasciola gigantica, Schistosoma sp . and echinostomes were found in snails from Surade . The larval echinostomes found in L. rubiginosa and adult echinostomes in domestic ducks and village chickens which grazed harvested rice fields in Bogor regency were both identified as Echinostoma revolution. The adult echinostomes were not found in the 24 rats, 11 lizards and 35 frogs caught in the vicinity of the Bogor regency . The possible sources of strigeids, Trichobilharzia and Xiphidiocercariae are discussed . Key words: Fasciola gigantica, trematode, larvae, Lymnaea rubiginosa
