Occurrence of seroagglutinins against a polyvalent preparation of commonly occurring Salmonella somatic groups in farm animals and man.

Abstract

A large proportion of human and animals' (buffaloes, sheep and mares) serum samples contained haemagglutinins against a polyvalent preparation of commonly occurring Salmonella somatic groups (4, 12; 4, 5, 12; 6, 7; 9, 12; 3, 10; 11 and 16) by indirect haemagglutination test (IHA). The inhibition of Salmonella haemagglutinins in serum samples of man and animals by 2-mercaptoethanol indicated that IgM moiety of immunoglobulins mainly participated in haemagglutination. The detection of haemagglutinins in large numbers of serum samples of animals and human at a titre of 1/80 or more by IHA may be considered important from Salmonella surveillance point of view.
