title: Experimental Caryospora bigenetica (Apicomplexa: Eimeriidae) infections in swine (Sus scrofa).
abstract: Two Hampshire-Landrace crossbred pigs were found to contain developmental stages of Caryospora bigenetica following oral inoculation with 1 x 10(8) oocysts. One pig was given intramuscular injections of methylprednisolone acetate. Both pigs displayed clinical signs of dermal coccidiosis from 3 to 10 days after inoculation, including swollen jowls and hocks, bilateral ocular discharges, generalized erythema, and lethargy. Meronts and gamonts were observed histologically in numerous tissues including jowl, ear, footpad, tongue, and lung at 10 days postinoculation. The present study is the first report of C. bigenetica infections in swine.
