To throw further light on the relationship between pediococci and aerococci, rabbits were immunized with cell antigens from 13 Pediococcus and 12 Aerococcus strains. All the immune sera prepared displayed relatively high agglutination titres. The pediococci from brewery products (11 strains), classified as Pediococcus damnosus , showed 100% mutual serological binding capacity (group binding). If account is taken of all the strains tested, the pediococci displayed a serological group binding of about 86% and the aerococci a corresponding binding of about 73%. All strains agglutinated with their homologous antisera. Of the cross‐agglutination tests carried out with Pediococcus antiserum against Aerococcus antigen (about 5% positive) and Aerococcus antiserum against Pediococcus antigen (about 30% positive), an average of about 18% displayed a binding capacity. The pediococci appear to represent a homogeneous serological group, whereas the aerococci are clearly mutually more serologically indifferent. A lack of serological binding capacity, especially between Pediococcus antiserum and Aerococcus antigen, shows that there is a very limited serological kinship between these two groups of bacteria.
