We studied C. trachomatis (CT) serotype-specific antibodies in Finnish women between 1980’s and 2000’s. C. trachomatis seropositive women (1,169) were available from a subcohort (11,067) of the Finnish Maternity Cohort representing the 1980’s (N = 480) and 2000’s (N = 331) for serotype specific classification by microimmunofluorescence test. Serotype distributions were comparable in the 1980’s and 2000’s, G, E and J being the most prevalent. Serotype D peaked in the 1990’s. The overall serotype profile changed first between 1980’s and 1990’s but changed back in the 2000’s. The rates of women with antibodies against two or more serotypes increased in the 1990’s, but then decreased again. In conclusion, we analysed the rates and distributions of CT serotype-specific antibodies from the 1980’s to 2000’s in fertile-aged female population in Finland. We found that CT serotype distributions varied considerably over time.
