In theileriosis, fever occurs 7–10 days after parasites are introduced by feeding ticks, may be >106°F (41°C). Lymph node swelling becomes pronounced and generalized. Anorexia develops, and the animal rapidly loses condition; lacrimation and nasal discharge may occur. Just before death, a sharp decrease in body temperature is usual, and pulmonary exudate pours from the nostrils. Death usually occurs 18–24 days after infection.
