The Weil-Felix test was developed by Weil and Felix in 1916. It is a heterophile agglutination test due to the antigenic sharing between species of proteus and rickettsia. Antibodies produced against rickettsial antigen cross reacts with OX19 and OX2 strains of Proteus vulgaris and OXK strains of Proteus mirabilis.
The Biorex Diagnostics Proteus OX19 stained febrile antigen suspension can be used to identify and quantitate specific antibodies in human sera following infection with certain Rickettsiae pathogens. Proteus OX19 reacts strongly with the sera of patients with typhus group rickettsae and rocky mountain of spotted fever.
