FIG. 2.

HLA-B27 expression does not affect infection of BLCL with C. trachomatis. Dot plots of forward scatter against fluorescence are shown for various BLCL infected with C. trachomatis at a multiplicity of 10:1 and stained after 24 h with anti-EB–FITC. The presence or absence of HLA-B27 expression and the donor origin of the cell lines are indicated. No staining was apparent with mock-infected cells (not shown). The results shown are representative of five similar experiments.
