New host and locality record for Trypanosoma peromysci.

ABSTRACT

Trypanosoma peromysci Watson, 1912 (Sarcomastigophora Kinetoplastida), is described from a new host and locality. One of 20 (5.0%) Peromyscus leucopus collected from Pottawatomie and Riley counties in Kansas was found to harbor the parasite. Morphometric and statistical analysis confirmed the trypanosome to be indistinguishable from T. peromysci, the only difference being a greater mean flagellar length than reported previously. This is the first reported occurrence of T. peromysci in the white-footed mouse (Peromyscus leucopus noveboracensis Fischer, 1829) and also the first record of its occurrence in Kansas.
