The Natural Occurrence of Echinococcus Multilocularis in the Bushy-Tailed Woodrat, Neotoma Cinerea Rupicola, in Wyoming

Abstract

Echinococcus multilocularis Leuckart, 1863, is reported from Neotoma cinerea rupicola Allen in Wyoming. This report represents new host and locality records for the cestode. The larva had undergone active multilocular vesiculation in the liver with minimal host-tissue reaction. Protoscolices and calcareous corpuscles were absent.
