[Rapid diagnosis of Crimean hemorrhagic fever in the indirect reaction to hemagglutination].

The possibility of using indirect hemagglutination test (IHA) with erythrocyte immunoglobulin diagnosticum for detection of CHF virus in the blood of patients early after the onset was studied. It was shown that viremia could be detected by the IHA test within 2-3 hours provided the blood was collected not later that 8 days after the onset of the disease. The sensitivity of the test for the detection of viremia is as high as that of bioassays.

Serological studies on sandfly fevers in the Republic of Bangladesh.

Blood samples from 160 inhabitants of the Republic of Bangladesh were studied by haemagglutination inhibition (HI), indirect HI, and radial haemolysis in gel tests. The sera were found to contain antibodies to the arborviruses of Sicilian (6.25%) and Naples (1.

[Indirect hemagglutination test for indicating the HFRS virus and the laboratory diagnosis of the disease].

Conditions have first been developed for the preparation of erythrocyte immunoglobulin diagnostic preparation of erythrocyte immunoglobulin diagnostic preparation for HFRS virus which permits express detection of the specific virus antigen in suspensions of the lung tissue of rodents by means of the indirect hemagglutination test (IHA) and laboratory diagnosis of the infection in humans by means of antibody detection by the indirect hemagglutination-inhibition test (IHAI). The IHA test is as sensitive as immunofluorescence, while the sensitivity of the IHAI test is not inferior to that of immunofluorescence but is higher than that of RIA.
