Comparative studies on the life history of Angiostrongylus mackerrasae Bhaibulaya, 1968 and Angiostrongylus cantonensis (Chen, 1935)

The life history of A. mackerrasae was found to differ from that of A. cantonensis as follows: (1) the moulting times of A. cantonensis in the definitive host occurred a few days earlier than those of A. mackerrasae; (2) the growth rate of A. cantonensis was more rapid than that of A. mackerrasae. However, there were no differences in the migratory pattern of the third-stage larvae of both species in experimentally-infected definitive hosts. It is concluded that Mackerras & Sandars (1955) described the life history of A. mackerrasae and not A. cantonensis.
