Abstract

Helminths of nine species were identified from 39 cougars obtained in northeastern Oregon (Walbowa, Baker, and Union counties), viz., Taenia omissa Lühe, 1910 (100%); T. ovis krabbei Moniez, 1879 (61%); T. hydatigena Pallas, 1776 (10%); Mesocestoides lineatus (Goeze, 1782) (5%); Toxascaris leonina (von Linstow, 1902) (69%); Toxocara cati (Schrank, 1788) (15%); Physaloptera praeputialis von Linstow, 1889 (13%); Pterygodermatites affinis (Jagerskiold, 1904) (ca. 2%); and Trichinella sp. (larvae) (ca. 2%). In addition, undeveloped cestodes of the genus Taenia in 26 animals had lost rostellar hooks and could not be identified. Host-records, prevalence, and biological characteristics of some of the helminths are discussed.Copyright
