The authors studied the avidity of antibodies in the sera obtained from 56 patients suffering from salmonelloses, the causative agents of which were referred to groups B, C1, C2, E. Determinations were carried out in the indirect hemagglutination inhibition test. It was shown that the mentioned test could be used to assess the extent of the serum antibodies avidity. Age-specific avidities of the serum antibodies were revealed in patients suffering from salmonella infections during the infectious process. There was found an insignificant prevalance of the antibody avidity in the patients with the forms of the disease of moderate severity and severe. In the patients with salmonelloses of group B the antibodies proved to be the most avid.
