Abstract
A method and a stable reagent for the detection of pathogenic bacterial infections in humans, and in particular, a stable diagnostic composition comprising non-degraded streptolysin-O protein directly adsorbed onto polystyrene latex particles and method of use are disclosed. The reagent may be prepared by adsorbing one or more layers of the streptolysin-O toxin onto the surface of the latex particle, effecting an intermolecular cross-linkage of the streptolysin-O, and further stabilizing the reagent by the addition of a bacteriostatic agent. Accordingly, the present invention provides a significant advance regarding the qualitative determinations of streptococci infections by providing a stable diagnostic reagent and method for such determinations.
