Abstract: | Yoshimura K., Aiba H. and Oya H. 1979. Transplantation of young adult Angiostrongylus cantonensis into the rat pulmonary vessels and its application to the assessment of acquired resistance. International Journal for Parasitology9: 97–103. A simple procedure for the transplantation of young adult Angiostrongylus cantonensis into the rat pulmonary vessels was described and its potential usefulness was discussed. Acquired resistance to A. cantonensis was conferred on rats by infection with 30 third-stage larvae or by a similar infection followed by treatment with thiabendazole during 14–19 days postinfection. Nearly comparable levels of resistance to reinfection were also observed in rats that were transplanted with 30 young adult worms, collected from the brain surface of donor animals at 21 and 22 days postinfection. The time-course development of reaginic, hemagglutinating and precipitating antibodies differed in these groups of rats although there appeared to be no positive correlation between the appearance of these antibodies and acquired resistance. |
