Migration and development of Paragonimus kellicotti were studied in cats killed between 1 and 265 days after feeding 15--20 metacercariae from the hearts of naturally infected crayfish. Metacercariae excysted in the intestine and appeared in the peritoneal cavity within 24 hr. Some young flukes penetrated the diaphragm and migrated to the pleural cavity during the first week, but the majority penetrated the pleura between 10 and 14 days. No flukes were found in the pleural cavity after 23 days postinfection. By 4 weeks postinfection, the flukes were well established within lung parenchyma, mainly in the right caudal lobe, where most of their growth occurred. Eggs first were seen in flukes on the 34th day postinfection and in feces 2 days later. Estimated daily ova production ranged from 1,000 to 2,000 eggs/fluke/day.
研究了克氏并殖吸虫在猫体内的移行和发育情况。给猫喂食15 - 20条来自自然感染小龙虾心脏的囊蚴，在喂食后1至265天处死这些猫。囊蚴在肠道内脱囊，并在24小时内出现在腹腔。一些幼吸虫在第一周内穿透膈肌迁移到胸腔，但大多数在10至14天之间穿透胸膜。感染后23天胸腔内未发现吸虫。感染后4周，吸虫在肺实质内发育良好，主要位于右尾叶，大部分生长在此处。感染后第34天在吸虫体内首次见到虫卵，2天后在粪便中发现虫卵。估计每条吸虫每日产卵量为1000至2000个。
