Gastrointestinal parasitism of Iowa coyotes in relation to age.
Taenia sp., Physaloptera sp., Ancylostoma caninum, Toxascaris leonina, and/or Trichuris vulpis were recovered from gastrointestinal tracts of 141 and 144 (97.9%) coyotes ranging from 1/2 to 8 1/2 years of age. Ancylostoma caninum exhibited a significant decline in both prevalence and mean number per coyote with increasing age of the host. Taenia sp. appeared with consistently high prevalence in all age classes. Physaloptera sp. and T. leonina showed general reductions in prevalence in all age classes. Physaloptera sp. and T. leonina showed general reductions in prevalence and mean nubmer with increasing host age, although the data were not statistically significant. Coccidia were found in 15 of 58 (25.9%) fecal flotations.
