The Life History of Echinostoma rodriguesi sp. n. (Trematoda: Echinostomatidae)

Abstract
The life cycle of E. rodriguesi, a new 37-spined echinostome from Brazil, is described. One sporocyst generation and at least 2 redial generations developed in the 1st intermediate host, Physa rivalis. The same physid snail, or the planorbid snail, Biomphalaria glabrata, served as the 2nd intermediate host in the laboratory. Adults were obtained from experimentally infected chicks, pigeons, hamsters, and mice.
