Detection of a Healthy Carrier of Virus of Poliomyelitis Without History of Contact. ∗

Abstract

Summary

1. Tonsil and adenoid tissue obtained from a healthy child 2 years old, without any history of contact, produced the experimental disease when inoculated into 2 animals, 2. One of the animals, Monkey 107, recovered with atrophy and contractures involving the right lower extremity. 3. The other animal sacrificed in the acute stages of the disease showed histologie evidence of poliomyelitis and the material from the cord of this monkey has produced the frank recognizable disease with paralysis in the third and fourth passages (Monkeys 391 and 409).

This investigation is being continued on a more extensive scale with the collaboration of Dr. M. Schaeffer of the Department of Bacteriology, New York University, with material obtained from the Jewish Hospital of Brooklyn. It is hoped that by including other sections of the community, a more exact estimate of the carrier rate and the geographic and seasonal distributions can be made.
