Rabbits of the New Zealand White and Small Chinchilla breeds were each infected at 3-4 months of age with 4-10 thousand invasive trichostrongyle larvae. Prepatent period of the infection was 22-32 days. Third-stage larvae were present up to the 6th day of infection, fourth-stage from the 8th day, fifth-stage from the 14th day and sexually mature trichostrongyles on the 18th day. The period of patency of the infection lasted for over a year, but only small numbers of eggs were passed in faeces, and food intake was not affected. Between 14 and 44% of the third-stage larvae developed into sexually mature nematodes, regardless of infection dose or duration of infection.
