Isolation of encysted Toxoplasma gondii from musculature of moose and pronghorn in Montana.

Pieces of skeletal muscle from 43 mule deer, 34 elk, 4 white-tailed deer, 21 pronghorn, 7 moose, and 2 bison were examined for Toxoplasma infection, by the acid-pepsin digestion technique. Toxoplasma gondii was isolated from 1 moose and 1 pronghorn. The isolated strains of T gondii were of low virulence to mice.
