Lesions in goats fed Toxoplasma gondii oocysts.
Tissues of 20 2-3-month-old kids and 17 2-4-year old does fed Toxoplasma gondii oocysts were examined histologically. Kids were necropsied between 3 and 50 days post-inoculation (DPI) and does were necropsied between 10 and 422 DPI. Lesions were seen in tissues of all young goats fed 1000-100,000 oocysts and consisted of acute enteritis, necrosis of mesenteric lymph nodes and encephalomyelitis. Lesions were not seen in does fed 10-10,000 oocysts.
