[The rapid diagnosis of salmonellosis by a determination of the antigen in the biosubstrates of patients using the coagglutination reaction].

The diagnostic potential of the coagglutination test was checked with the aim of improving the laboratory diagnosis of Salmonella infections by the detection of Salmonella specific antigen in different biological materials (feces, urine, saliva and immune complexes in blood sera). The study of all specimens resulted in the confirmation of the diagnosis in 78% of patients, often during the first days of the disease. The proportion of nonspecific reactions, as shown in the control groups of healthy donors and patients with dysentery and other acute enteric infections, did not exceed 5%.
