Abstract

The occurrence of characteristic agglutinogens has been searched for in the type strains of the following species: Staphylococcus xylosus, S. cohnii, S. epidermidis, S. capitis, S. saprophyticus, S. warneri, S. haemolyticus, S. hominis and S. simulans. Serotyping of these nine strains and study of their antisera have been carried out with formalin-treated and autoclaved bacteria. It has been shown that the characteristic agglutinogens of S. epidermidis and S. haemolyticus were respectively identical to the agglutinogens previously described in the coagulase-negative type strain 52.186 and in the S. aureus type strain 18. Characteristic agglutinogens have been found in each of the other seven type strains. Agglutinogens found in S. xylosus and S. saprophyticus are thermolabile, the corresponding absorbed sera reacting only with the formalin-treated homologous strain. Concerning S. cohnii, S. capitis, S. hominis and S. simulans, their absorbed sera reacting both with formalin-treated and autoclaved homologous strains, the observed reactions can be accounted either by one thermostable agglutinogen or by two characteristic agglutinogens, one thermostable, the other thermolabile. In S. warneri, only one thermostable agglutinogen has...Continue Reading

Antibodies: Agglutination

Antibody-mediated agglutination is the clumping of cells in the presence of antibody, which binds multiple cells together. This enhances the clearance of pathogens. Find the latest research on antibody-mediated agglutination here.
