Rabbits that received single inoculations by mouth of irradiated larvae of Trichinella spiralis failed to produce antibodies in sufficient amounts to be detected by the flocculation and complement-fixation tests. Multiple feedings with irradiated larvae produced a positive serology at low titers and of brief duration. Extra-intestinal larval inoculations stimulated the production of antibodies in relatively high titers. A re-evaluation of the significance of positive serology in trichinosis might become necessary if the recommendation of commercially irradiating pork as a means of protecting human beings from trichinosis should be widely adopted.
