Abstract

Fourty guinea pigs were employed to investigate the nature of les ions produced in lugns and liver by repeated infection using larvae of Neoascaris vitulorum per os. The liver and lungs presented pro gressive lesions with the repeated infection. The pulmonary lesions were manily focal granulomatous, and the hepatic ones were chiefly focal necrotic with eosinophilic infiltration.
Hypersensitivity was concluded to play a major role in pathogeno sis of the lesions. Immunity was also considered.
