Innate and adaptive resistance of Indonesian Thin Tail sheep to liver fluke: a comparative analysis of Fasciola gigantica and Fasciola hepatica infection.

In the current study, three independent trials directly compared Fasciola gigantica and Fasciola hepatica infection of ITT sheep. In all trials, F. hepatica infection resulted in higher worm burden recoveries and greater physiological damage to ITT sheep.

Immune responses in Indonesian thin tail and Merino sheep during a primary infection with Fasciola gigantica: lack of a specific IgG2 antibody response is associated with increased resistance to infection in Indonesian sheep.

After a primary infection with Fasciola gigantica, the immune responses in a resistant (Indonesian thin tail) and a susceptible (Merino) breed of sheep were analysed. The number of adult flukes recovered from the livers of the Indonesian thin tail sheep were significantly lower than those found in the Merino animals. On days 8, 14 and 25 p.

Evaluation of antigens of Fasciola gigantica as vaccines against tropical fasciolosis in cattle.

Vaccine trials were conducted in Brahman cross cattle evaluating the efficacy of 4 native antigens purified from adult Fasciola gigantica flukes, and 1 recombinant F. gigantica antigen, as vaccines against tropical fasciolosis. The antigens tested were native glutathione S-transferase, cathepsin L, paramyosin, fatty acid binding protein (FABP), and a recombinant FABP expressed in E.

Control of Fasciola gigantica with triclabendazole in Indonesian cattle.

The efficacy of triclabendazole (TCBZ) against natural infections with Fasciola gigantica was evaluated in a field study using 102 Indonesian cattle. The animals were divided into two groups; one received TCBZ at 12 mg/kg orally every eight weeks for one year while the other remained untreated. Relative to controls the Fasciola faecal egg count in treated animals was significantly reduced (P less than 0.
