Formal, Samuel B., (Walter Reed Army Institute of Research, Washington, D.C.), T. H. Kent, S. Austin, and E. H. LaBrec. Fluorescent-antibody and histological study of vaccinated and control monkeys challenged with Shigella flexneri. J. Bacteriol. 91:2368-2376. 1966.-Groups of monkeys were fed four doses of a living Escherichia coli-Shigella flexneri 2a hybrid strain, and, together with control animals, were challenged with virulent S. flexneri 2a. Two experiments were carried out; in the first, the animals were challenged 10 days after and in the second, 1 month after the last vaccine dose was administered. At 48 hr after challenge, tissues were removed from the vaccinated and control animals, and examined by use of histological and fluorescent-antibody techniques. The results of this study demonstrate that the animals receiving the vaccine were protected from the tissue damage ordinarily observed after experimental challenge with virulent dysentery bacilli. The virulent challenge strain appeared to be unable to penetrate into the intestinal mucosa of immunized animals.
