Prevalence of Dictyocaulus viviparus lungworm in elk was previously determined, (1968-74) by elk fecal analyses during spring, summer and winter of each year and by elk lung dissections during the fall hunting season. Percentages positive for and numbers of D. viviparus larvae in elk feces was monitored during the fall hunting season of 1975. Fifteen percent (5 to 33) of the elk checked were positive for D. viviparus according to lung dissections conducted during the period of November 15-18, 1975, in Teton Park.
