Abstract
There have been many reports on the serum-agglutination of dysentery in order to make the estimation of the types of the infecting Shigella. However, most of these reports dealt with adult cases. The authors conducted agglutination tests on 21 children's dysentery cases, upon the expectation of finding some changes in the agglutination titres, which might be specific.
Serum used was collected on the day of hospitalization and on the 7th, 14th and 21st day of the dysentery, in each case.
Results were follows:
1) Generally, agglutination titres showed maximum value in the second week.
2) The average maximum agglutination titre of the isolated bacilli was 1: 270.
3) The agglutination titre of the isolated bacilli and the respective standard strains corresponding to the isolated bacilli rose in proportion.
4) There were no isolated bacilli, corresponding to the respective standard strains, which gave special increase in the agglutination titres.
5) There was no effect on the agglutination due to the common structure antigen, according to the international classification.
The authors came to the conclusion that it is difficult to suppose the types of infecting Shigella from the agglutination tests in the dysentery of children.
