A study of the coccidia of the Uinta ground squirrel, Spermophilus (Citellus) armatus, was undertaken to determine the incidence of coccidia in a population of these ground squirrels, the life cycle and pathogenicity of the coccidia, and the host specificity of certain of the species of coccidia found in this and five other species of ground squirrels (S. richardsoni, S. variegatus, S. lateralis, S. columbianus, and S. beecheyi).

Uinta ground squirrels were live trapped and their feces examined to determine the incidence of coccidian infection. Specimens of S. armatus were maintained in the laboratory and given a pure inoculum of …
