Chemical Studies on Bacterial Agglutination

1. A method, conforming to the criteria of quantitative analytical chemistry, is described for the estimation of the agglutinin content of antisera. Examples are given of the application of the method to various antipneumococcus sera. 2. This new, absolute method is discussed with regard to its relation to the commonly used relative methods.

Chemical Studies on Bacterial Agglutination Vi. the Agglutinin Content of ~tisera to Hemolytic Streptococci

In most of the bacterial agglutinating systems previously studied by the quantitative method (1-5) well defined capsular polysaccharide antigens and their corresponding antibodies were principally involved. The greater part of the antibody produced as a result of intravenous injections of microorganisms such as type-specific pneumococci or It. influenzae reacts with these capsular antigens, rel...

Chemical Studies on Bacterial Agglutination Ii. the Identity of Precipitin and Agglutinin*

Although the unit&an theory of antibodies has gained general acceptance since its formulation by Zinsser and others (l), quantitative evidence for the identity of agglutinins and precipitins has been lacking. Zinsser (2) has attempted to reconcile mathematically the apparent discrepancy between the serum dilutions in which agglutination and precipitation occur and Jones (3) has shown that collo...

Studies on Thrombin-induced Platelet Agglutination

A one-stage macroscopic test for platelet agglutination was used to study the effect of thrombin and thrombin-cation mixtures on washed platelets. Conclusions regarding platelet agglutination are as follows: (a) Canine, bovine, or human thrombin alone does not cause agglutination of canine or human platelets. (b) Thrombin with calcium or magnesium causes rapid platelet agglutination. Both calci...

Latex agglutination testing in bacterial meningitis.

The value of the latex agglutination test in meningitis was assessed. This was positive in 60% cases of Streptococcus pneumoniae, 93% of Haemophilus influenzae type b, and 39% of Neisseria meningitidis infections. We cannot support the view that this test was more valuable than Gram staining in partially treated meningitis and cannot recommend its routine use. It may, however, be valuable if Gr...
