一种特殊的肺吸虫——亚马孙并殖吸虫新种,是从瓦努科省延果——马利亚市的四只哺乳动物中的两只,一只四眼袋鼠(Philander opossum)和一只水袋鼠(小蹼足袋鼠)的肺内所得虫体加以描述的。作为此新种的鉴定,下列诸点是重要的;1)虫体非常细长;2)皮棘多半单生;3)口吸盘约与腹吸盘等大,腹吸盘位置很靠前;4)卵巢较细密地分支;5)辜丸分为六块且稍大于卵巢,但与虫体相比很小;6)子宫坐落稍呈双侧性;7)卵细长且卵壳薄而有起伏。推测其宿主蟹是智利拟束腹蟹,但后囊蚴现尚不知。该新种有人体感染的可能性。
A special paragonimiasis, a new species of Paragonimus y Amazonian, is two of four mammals from the Yanagula-Malia city of Van Nuco, a Philadelphus opossum and a water Kangaroo (webbed kangaroo) in the lungs of the parasites described. As the identification of this new species, the following points are important; 1) the parasites are very slender; 2) the spines are mostly single; 3) the mouth sucker is about as large as the abdominal sucker; 5) The testis is divided into six and slightly larger than the ovary, but very small compared with the parasites; 6) The uterus is slightly bilateral; 7) The egg is long and the egg shell is thin and undulating . Speculated that the host crab is Chile to be crab crab, but the cecropia is still unknown. The new species has the potential of human infection.
