One hybrid strain of each of the serotypes was chosen for study of their biological characteristics. Their capacity to cause a fatal enteric infection in starved guinea pigs was reduced, they failed to cause dysentery when fed to monkeys, they caused keratoconjunctivitis in the guinea pig eye, and they penetrated HeLa cells. Two doses of a polyvalent oral vaccine composed of\n            <jats:italic>S. flexneri<\/jats:italic>\n            1b, 2a, and 3, and\n            <jats:italic>S. sonnei<\/jats:italic>\n            I hybrid strains were fed to groups of monkeys at an interval of 4 to 7 days, and they, together with controls, were challenged 10 days after the last dose with one or another of the virulent parent dysentery strains. A significant degree of protection was afforded in all vaccinated groups with the exception of one group challenged with\n            <jats:italic>S. flexneri<\/jats:italic>\n            6, a component not included in the vaccine. When animals were challenged with virulent\n            <jats:italic>S. flexneri<\/jats:italic>\n            2a 1 month after oral vaccination, they were also protected. The vaccine produced a rise in serum antibody, but we were not able to detect coproantibody in saline extracts of feces from animals which received the vaccine.\n          <\/jats:p>","DOI":"10.1128\/jb.92.1.17-22.1966","type":"journal-article","created":{"date-parts":[[2020,1,5]],"date-time":"2020-01-05T01:54:19Z","timestamp":1578189259000},"page":"17-22","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":70,"title":["Protection of Monkeys Against Experimental Shigellosis with a Living Attenuated Oral Polyvalent Dysentery Vaccine"],"prefix":"10.1128","volume":"92","author":[{"given":"Samuel B.","family":"Formal","sequence":"first","affiliation":[{"name":"Walter Reed Army Institute of Research, Washington, D.C., and National Institutes of Health, Bethesda, Maryland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.
