Experimental light infection of Angiostrongylus cantonensis in hamsters

An experimental infection with a small number of larvae of A. cantonensis in hamster was carried out. When hamsters were infected with one larva, infection rate and recovery rate were 66.7%. In the case of infection with more than two larvae, all hamsters were infected had recovery rates were around 65%. The recovered worms were all matured and showed no important morphological differences. It was concluded that the hamster would be able to serve as a final host for A. cantonensis only in the case of a small number of larvae infection.
