Since Waddlia chondrophila is closely related to Chlamydia trachomatis, we hypothesise that W. chondrophila may also be associated with tubal factor infertility (TFI) in women, a major complication of chronic C. trachomatis infection. Five hundred twenty serum samples were tested for anti-Waddlia antibodies by ELISA. Among the 520 investigated women, a total number of 142 (27.3%) has had laparoscopic diagnosis performed, and were either classified TFI positive or negative. Presence of high titres of W. chondrophila antibodies was linked to TFI (p <0.0001; OR: 7.5; 95% CI: 3.3-17). Moreover, antibody positivity to both W. chondrophila and C. trachomatis-MOMP was strongly associated with TFI (p <0.0001; OR: 21; 95% CI: 3.8-12E1). This association was much stronger than the statistical association of C. trachomatis-MOMP antibodies only (p <0.0001; OR: 7.1; 95% CI: 3.7-14), suggesting that co-infection with W. chondrophila and C. trachomatis may lead to more severe reproductive sequelae and immune responses than single infection with either Chlamydiales members.
