Molecular Identification of an Avian Dicrocoeliid, Brachylecithum mosquensis, from a Vagrant Shrew, Sorex vagrans, in Montana, U.S.A

Gravid dicrocoeliid flukes recovered from the liver of a vagrant shrew, Sorex vagrans, in Montana, U.S.A., were identified as Brachylecithum mosquensis by comparing their morphology and DNA sequences to specimens from 2 American robins, Turdus migratorius, from North Dakota, U.S.A. This is the first record in the world, to our knowledge, of a bird dicrocoeliid from a shrew and also the first record in North America of a dicrocoeliid parasitic in the genus Sorex.
