World association for the advancement of veterinary parasitology (WAAVP): second edition of guidelines for evaluating the efficacy of anthelmintics in swine.

Guidelines are provided for evaluating the efficacy of anthelmintics in swine which, in conjunction with other sets of guidance such as those of the International Cooperation on Harmonization of Technical Requirements for Registration of Veterinary Medicinal Products (VICH GL7 and VICH GL16), should encourage the adoption of uniform registration requirements globally. Testing of efficacy should be carried out according to the principles of "Good Clinical Practice" (VICH GL9, 2000). Data obtained according to these guidelines should be internationally acceptable for the registration of anthelmintics for swine.

Response of two isolates of Fasciola hepatica to treatment with triclabendazole in vivo and in vitro.

In this study, the susceptibility of two isolates of Fasciola hepatica--the Fairhurst and Oberon isolates--to treatment with triclabendazole was investigated, both in vivo and in vitro. The Fairhurst isolate originated in England, but has since been maintained in Australia; the Oberon isolate originated in Australia. Triclabendazole had a very high efficacy against the Fairhurst isolate.

Fasciolicides: efficacy, actions, resistance and its management.

The modes of action of fasciolicides are described. Closantel and other salicylanilides interfere with energy metabolism by uncoupling oxidative phosphorylation in the fluke. Other fasciolicides are believed to have a metabolic action-halogenated phenols (via uncoupling) and clorsulon (via inhibition of glycolysis)-but direct evidence is lacking.

Fasciola hepatica infection in farmed emus (Dromaius novaehollandiae).

Objective: To describe two cases of infection with Fasciola hepatica in young farmed emus, subacute and chronic fasciolosis and a response to treatment of the flock with albendazole.

Procedure: Gross lesions were found at necropsy and hepatic lesions in microscopic examination. The parasite recovered from one emu was identified by its morphological characteristics and an egg count reduction test was carried out after treatment of the flock with albendazole.

Zoonotic potential of infection with Fasciola spp. by consumption of freshly prepared raw liver containing immature flukes.

Mice were successfully infected with metacercariae of the Japanese Fasciola sp., resulting in the recovery of a mean number of 110 live immature flukes per mouse 4-5 days after inoculation. Twenty-four mice were then inoculated orally, each with a mean number of 68 freshly recovered immature flukes.
