Induced toxoplasmosis in pronghorns and mule deer

Two mule deer and 2 pronghorns were inoculated intraruminally with infective oocysts (deer with 100,000 each, and pronghorns with 100, and 10,000) of the GT-1 strain of Toxoplasma gondii. The deer died 7 and 11 days after inoculation, and the pronghorns died 13 and 19 days after inoculation. Necropsy findings were typical of acute toxoplasmosis.
