Lymphonodular white spots were detected in the lung of slaughtered pigs with pulmonary petechiae and multiple milk spots in the liver. These noduli mainly consisted of follicular hyperplasia of lymphoid cells, including a few sections of the third stage larvae of Ascaris suum at the center of the foci in some cases. A number of Ascaris suum eggs were frequently detected in feces of pigs with pulmonary lymphonodular lesions.
