OBJECTIVES: To describe the discovery in a domestic pig of the first case of trichinellosis in Papua New Guinea, caused by a new taxon within the genus Trichinella (T papuae). Also, to establish if the disease occurred in the local wild pig population and in domestic pigs elsewhere in the country, and to test if the worm was infective to some other animals.
PROCEDURE: Fresh and fixed tissue samples were examined by the digestion method and histologically, respectively, for the non-encapsulated larvae of T papuae. Feeding trials were conducted, using infected tissues and infective larvae, on animals under laboratory conditions.
RESULTS: About 8.8% of a wild pig population in Western Province, adjacent to Irian Jaya, Indonesia, was found to be infected. Infection was not found in other local and feral animals or in domestic pigs from other parts of the country. Infection was experimentally established in cats, pigs and laboratory bred mice and rats.
CONCLUSION: Trichinellosis is confined to one remote locality in PNG. Domestic pigs in the initial case became infected, probably, by eating infected wild pig meat.
