Chlamydial antigens stabilized with formalin for use in the micro-immunofluorescence test

Single-antigen immunofluorescence test for chlamydial antibodies.

A simple method is presented for producing large numbers of inclusions of Chlamydia trachomatis serotype L2 in cell cultures on slides for immunofluorescence antibody staining. Preliminary results with a total of 1,241 human sera from different groups were consistent with findings by earlier methods: 82% of chlamydia-positive men with nongonococcal urethritis had antibodies at titers of greater...
