  • Title: Host-parasite relationship of Angiostrongylus cantonensis. 1. Intracranial transplantation into various hosts.
    Author: Ko RC.
    Journal: J Helminthol; 1979 Jun; 53(2):121-6. PubMed ID: 479541.
    Abstract:
    Various stages of Angiostrongylus cantonensis recovered from the brain of experimentally infected mice were transplanted intracranially into rats. Third and fourth-stage worms recovered 2--7 days postinfection were able to develop normally after transplantation into recipient rats. The fifth-stage worm obtained 14--15 days postinfection would enter the brain tissue of rats but died shortly afterwards. However, the same stage of worms recovered from rats, after a similar transplantation, were found to develop normally in the recipient animal. Young fifth-stage worms, from the subarachnoid space of rats, which were ready for the pulmonary migration were also transplanted into rabbits but the worms failed to reach the lungs. In the control rat-to-rat transplantation, the worms successfully completed the pulmonary migration. The morphogenesis and initial growth rate of A. cantonensis were similar in both mice and rats but in the former host the worms started to grow at a markedly slower rate after the last moult and gradually degenerated.
