Summary

The behaviour of mice exposed to graded doses of Trichinella pseudospiralis larvae was monitored in an open-field situation. Ambulatory activity declined briefly during the acute phase of the infection (day 11) but regained pre-infection levels 1 week later. Animals receiving heavy doses of T. pseudospiralis exhibited a mild increase in the level of ambulatory activity during the chronic phase of the infection. The infections did not affect the level of exploratory activity. The effects of the T. pseudospiralis infections on the behaviour of the mouse host were much less pronounced than those induced by T. spiralis. It is suggested that these differences may be associated with the small size of T. pseudospiralis and the lack of capsule formation.
