[Serotype distribution of urogenitally located Chlamydia trachomatis in Rotterdam]

The distribution of serotypes in 208 Chlamydia trachomatis strains of urogenital origin isolated from 185 patients (87 women, 98 men) attending a sexually transmitted disease clinic in Rotterdam, the Netherlands, was studied. Typing by monoclonal antisera using a dot enzyme linked immunosorbent assay (ELISA) showed that the most common serotypes were E (found in 45 strains), F (39), D (34) and K (28). Other serotypes detected were H (21), G, I, I', J (2-12) and B (one strain). Mixed infection with two serotypes was detected in two patients. These results indicate that most genital infections with C. trachomatis result from a small number of serotypes, and that these are similar in the Netherlands and Seattle, U.S.A.
