FIG. 1.

Infectivity inhibition results with serovar E (a) and serovar LGV (b) at 37°C Comparison of C. trachomatis infectivity levels incubated on HeLa, Hec-1B, and endosalpingeal cell monolayers with addition of different GAGs: HP and chemically modified HPs (all used at 0.5 mg ml⁻¹). This figure represents the results of six different experiments. Error bars: standard error. Results were statistically analyzed using a one-way-paired analysis of variance test, and a Tukey-Kramer test was performed if there was a significant difference between the columns. ∗, P < 0.05; ∗∗, P < 0.01; ∗∗∗, P < 0.001.
