title: [Experimental infection of Paragonimus iloktsuenensis to albino rats, dogs and cats].
abstract: This study was performed to observe the susceptibility of dogs and cats as definitive hosts of Paragonimus iloktsuenensis. The metacercariae of this fluke were obtained from Sesarma dehaani collected at a focus near the mouth of Sumjin river in November, 1986 and February, 1987. The larvae isolated from the crabs were introduced per os into 7 albino rats, 2 dogs and 3 cats. The adults were recovered from the experimental animals, and they were morphologically observed and measured. The results were as follows: 1. The recovery rate of adult worms at 42 days after infection was 53.3% from three albino rats, 21.0% from a dog and 12.7% from two cats. Most of the worms were recovered from the worm capsules in the lungs. 2. The size of worms recovered from albino rats, a dog, and cats 42 days after infection averaged 6.3 x 3.2 mm, 6.3 x 3.0 mm, or 6.2 x 3.5 mm, respectively. There were little differences in the morphology of worms by different experimental animals. 3. The size of eggs from a dog was 88.9 x 49.3 microns, and that from cats was 84.3 x 53.7 microns on average. Dogs and cats were good definitive hosts of P. iloktsuenensis. This fact suggests that human infection by this fluke may be possible if the metacercariae were ingested.
