The generally accepted identifying characteristic of Staphylococcus aureus is the ability to produce free and bound coagulase (or clumping factor). The presence of clumping factor may be detected in a number of ways. The Oxoid Staphylase Test detects the presence of clumping factor through clumping of fibrinogen- sensitised sheep red blood cells. The specificity of the reaction is ensured by a simultaneous test with a control reagent (unsensitized sheep red blood cells), when of course no clumping reaction should be observed.
Use this rapid agglutination test for the identification of Staphylococcus aureus by detection of clumping factor. Clumping factor is detected through agglutination of fibrinogen-sensitised sheep red blood cells. The specificity of the reaction is ensured by a simultaneous test with a control reagent (unsensitized sheep red blood cells) when no clumping reaction should be observed. A positive result is obtained if clumping of the test cell suspensions occurs during mixing. This indicates the presence of Staphylococcus aureus.
Included in the kit is a test reagent consisting of rabbit fibrogen-sensitized sheep red blood cells, control reagent consisting of unsensitized sheep red blood cells, and disposable reaction cards.
