A specimen of Gongylonema, probably G. pulchrum, has been recovered from man. This species is normally a parasite of the pig.

Infection of the human host was brought about probably by the ingestion of larvae in the infective stage which had developed in some insect. Very likely the croton bug, known by experiment to be able to serve as intermediate host for this species, was the source of the infection which might readily occur by accident.

The presence of the parasite was accompanied by clinical symptoms indicating marked digestive and nervous disturbances, associated with anemia. These symptoms disappeared with the removal of the worm.

The parasite displayed a tendency to wander through the submucosal connective tissue from the lips to the throat.
