title: STUDIES ON THE FLEXNER GROUP OF DYSENTERY BACILLI : V. A QUANTITATIVE STUDY OF THE SEROLOGICAL CROSS-REACTIONS.
abstract: A quantitative study of the serological cross-reactions of the somatic antigens of Types I, III, and I-III Shigella paradysenteriae has been made. From the results obtained it has been concluded that the somatic antigens of Shigella paradysenteriae (Flexner) Types I, III, and I-III are single chemical substances. The specificity and serological cross-reactions exhibited by these antigens are dependent upon similarities in their chemical constitutions.
