[The demonstration of specific Salmonella typhi antigens by the latex agglutination method]

The evaluation of the diagnostic importance of the method of latex agglutination with antibody diagnostica for the detection S.typhi O and Vi antigens in biosubstrates obtained from patients is presented. The clinical approbation of the method has made it possible to characterize its diagnostic specificity (whose indices varied from 95.8 to 100%), sensitivity and significant diagnostic effectiveness (67.7-91.3%). The method has been recommended for the early diagnosis of typhoid fever.
