[Differences in certain immunological indices among persons who have had cholera and among Vibrio carriers].

Blood sera of persons, who sustained cholera of different degree of severity, and of vibrio-carriers, and also chromatographic fractions obtained in separation of the mentioned sera on DEAE-cellulose were investigated in the reaction of agglutination and the indirect hemagglutination test. Immunological response in the vibrio carriers was realized by the microglobulin, and in the convalescents--by the macroglobulin type. There was also revealed an association between the severity of the course of cholera and the prevalence in the blood serum of one or another type of specific antibodies: in severe forms of the disease the antibodies of the IgM-class were detected with the greatest frequency, and microglobulin antibodies--in vibrio carriers. The detected differences in the immunological status of those who sustained cholera and of vibrio-carriers could be used as an additional differential sign in the diagnosis of the mentioned conditions.

[Utilization of serological methods in the retrospective diagnosis of cholera and in detecting vibrion carriers].

Sensitivity and specificity of the three serological methods were studied comparatively: the vibriocidal test, the reaction of bacterial agglutination and of indirect hemagglutination, with the use of erythrocytes sensitized with the vibrio lyzate, cholera species O-antigen and cholerogen. Investigations were conducted with the blood sera of cholera patients, vibrio carriers and contacts. Vibriocidal test proved to be the most sensitive; its data correlated with the results of bacterial agglutination and indirect hemagglutination with erythrocytes, sensitized with the lysate of the vibrios and the cholera O-antigen. None of the used serological methods provided a 100% coincidence with the results of bacteriological analysis. The frequency of detection of anticholera antibodies decreased in the following order: cholera patients, vibrio carriers, contacts.
