[Use of the thrombocyte aggregation test for detecting immune complexes circulating in the serum of cholera patients]

It was shown that the blood sera of patients suffering from cholera and of persons who had sustained the disease contained specific antibodies in titres below the diagnostic level (according to the indirect hemagglutination test) caused platelet aggregation, most pronounced during the first week of the infectious process. In the presence of a specific cholera antigen the phenomenon of platelet aggregation was considerably enhanced; the indices reached the maximum when the experiment was conducted with the blood sera of those who had sustained the disease.
