Agglutination of Staphylococcus aureus by Rabbit Sera

Abstract: Of 137 Staphylococcus aureus strains, 87 agglutinated in normal rabbit serum. The agglutination was shown to be caused by the Fc-part of immunoglobulin G (IgG). F(ab 1 ) 2 -fragments of IgG and immunoglobulin M (IgM) in corresponding concentrations were unreactive. The agglutinating strains had a high or moderate content of protein A. Strains with a low content of protein A and protein A-negative mutants did not agglutinate. The importance… Show more

“…Preparation of human IgM. Normal human IgM was separated by chromatography on a Sephadex G-200 column and further purified by chromatography on a DEAE-cellulose column as earlier described (5). In immunoelectrophoresis, a single line was detected against rabbit anti-human plasma protein serum and rabbit anti-human IgM serum (Behring Werke AG).…”

“…Виявлено [9 ], що аглютинацію стафілокока можуть виклика ти Fab-фрагменти IgG. Деякі дослідники [67] ді йшли висновку, що аглютинація штамів стафі локока, які містять білок А, -явище неспецифіч ного характеру, яке обумовлене здатністю білка А поєднуватися з Fc-фрагментами IgG. При високих концентраціях у сироватці специфічних IgG фено мен аглютинації може бути обумовлений і зв'язу ванням розташованого на поверхні клітин стафіло кока білка А специфічними рецепторами IgG.…”

“…It is now well known that S. aureus producing protein reacts with the F-part of immunoglobulin G (IgG) in normal sera (4,5,7). This paper presents evidence that a protein A-Fe reaction can be detected when nonencapsulated S. aureus strains are grown in serum-soft agar and that this reaction is mainly responsible for the compacting action of normal serum in soft agar.…”
