The development of the diploid type ofParagonimus westermaniin cats was examined.P. westermani, 1-hr-to 245-day-old, was recovered from cats experimentally inoculated with the metacercariae of this lung fluke and then morphologically classified into juvenile, immature, preadult and adult stages, based on the live and/or mounted specimens. Most flukes recovered at 1 hr to 7 days, at 14 to 28 days, at 35 to 70 days and at 98 to 245 days after inoculation, were at juvenile, immature, preadult and adult stages, respectively. The diameter of oral and ventral suckers as well as the length and width of flukes recovered were measured. The oral sucker was larger than the ventral one in every fluke of 140 days and older. The relationship between the migration route, location, and developmental stage of P. westermani in cats was discussed.
