Mixed field agglutination: Unusual causes and serological approach

Serological grouping of streptococci by slide agglutination.

Streptococcal grouping sera for groups A, B, C, and G prepared for conventional testing by precipitation were made specific by absorption and used to identify streptococci by slide agglutination with and without staphyloccocal coagglutination. Trypsinised suspensions of 1055 strains, identified by precipitation as belonging to group A, B, C, or G, were tested by slide agglutination. Of these, 9...

Mixed Agglutination with Tissue Sections

The mixed agglutination procedure was applied to tissue sections. Microtome sections of bovine tissue were placed on coverglasses, fixed by acetone or formalin, and incubated with various dilutions of rabbit antisera. The binding of antibodies to the tissue sections was detected by the addition of an indicator system composed of sheep erythrocytes sensitized by subagglutinating doses of the cor...

Serological Agglutination and Precipitin Mechanisms in Rheumatoid Arthritis

Streptococcal Agglutination In I929 Cecil and his colleagues observed that the sera of patients with rheumatoid arthritis had the property of agglutinating a specific strain of haemolytic streptococcus in high titre, and as this property was not present in the sera of control subjects, concluded that it was a specific manifestation of the disease (Cecil et al., 1929, I931). Later it was found t...
