[The use of passive hemagglutination for determining the fibronectin-binding properties of microorganisms]

The authors present the data that evidence in favour of employing fibronectin sensitized formalin-treated red cells for the indication of fibronectin-binding microorganisms (as exemplified by staphylococci) in the passive hemagglutination test (PHAT). The possibility of a quantitative estimation of fibronectin binding by the PHAT is shown. PHAT will help detect higher numbers of fibronectin-binding staphylococci than flocculation on the glass.
