Trypanosoma pipientis infections were achieved by exposing laboratory-raised bullfrog tadpoles (Rana catesbeiana) to the leech Desserobdella picta that had fed on infected frogs. Likewise, a laboratory-raised snapping turtle (Chelydra serpentina) was infected with Trypanosoma chrysemydis following exposure to infected Placobdella ornata. Transmission of the trypanosomes by these leeches constitutes new vector records for the parasites. The biology of D. picta and P. ornata suggests that they are more important in transmitting these flagellates than the species of leech previously reported as vectors.
通过将实验室饲养的牛蛙蝌蚪（牛蛙）暴露于以感染青蛙为食的水蛭Desserobdella picta，实现了皮氏锥虫感染。同样，一只实验室饲养的鳄龟（拟鳄龟）在接触受感染的华丽蛭后感染了龟锥虫。这些水蛭传播锥虫构成了这些寄生虫新的传播媒介记录。D. picta和华丽蛭的生物学特性表明，它们在传播这些鞭毛虫方面比先前报道为传播媒介的水蛭种类更为重要。
