A mean of 111±54 (± S.E.) N. alcidis was recovered from infected animals but only 21% of the specimens were mature adults. Immature specimens predominated at all times of the year sampled. Most were short, fourth-stage larvae (3.22-4.0 mm long), but longer fourth-stage (5.6 - 7.1 mm) and immature fifth stage worms (9.0 - 14.5 mm) were also present. It is suggested that the development of some <em>N. alcidis</em> in moose is arrested at the early fourth larval stage. Although sample sizes were small, host age, sex, and season did not appear to affect the prevalence or intensity of <em>N. alcidis</em>. Eggs of the tapeworm, <em>Moneizia </em>sp, were detected in the feces of only 2 of 17 moose. No abomasal nematodes or their eggs were found in any of the animals examined.</p> ER -
