THE USE OF SEROLOGICAL-IMMUNOBIOLOGICAL METHODS IN THE DIAGNOSIS OF TYPHOID CARRIERSHIP
ARMY BIOLOGICAL LABS FREDERICK MD

The report ties in with previous findings which were obtained in immunological study of typhoid carriers. In this study significantly higher values were found of indicators of specific phagocytic activity of the blood so-called phagocytic index-PI and significantly lower values of the indicators of bactericidal activity of the sera BA toward S.typhi in vitro so-called bactericidal index-BI in typhoid carriers as compared to non-carriers with a typhoid anamnesis and persons without a typhoid anamnesis. On the basis of these findings and of further analysis of the material the use of determination of specific PI is recommended as well as BI as helpful tests in the diagnosis of typhoid carriership, following the agglutination tests for Vi, as well as hemagglutination test for Vi.
