The chemiluminescent (CL) associated phagocytic response of peripheral blood monocytes to two serovars of Chlamydia trachomatis, Shigella flexneri and zymosan was assessed in a group of 26 patients with anterior uveitis (AU). HLA-B27+ patients with AU, when compared to HLA-B27 patients with AU and appropriate controls, had a significantly decreased CL response to C. trachomatis but no difference between groups in the response to S. flexneri and zymosan. The decreased chemiluminescent (phagocytic) response of mononuclear phagocytes to Chlamydiae may indicate an important abnormality in the pathogenesis of HLA-B27+ AU.
