Abstract
In this study, we investigated the prevalence of genital Chlamydia trachomatis isolated in Japan using a high-resolution genotyping method, the multilocus VNTR analysis (MLVA)-ompA typing method. Seventeen serotypes of C. trachomatis standard strain (A-L3) and 44 clinical isolates were obtained from clinical settings. Genotyping of the ompA gene allowed clinical isolates to be divided into nine serotypes: B (6.8%), D (15.9%), E (25%), F (20.5%), G (18.1%), H (6.8%), Ia (2.3%), J (2.3%), and K (2.3%). These isolates were further divided into 28 types after combining ompA genotyping data with MLVA data (Hunter-Gaston discriminatory index D, 0.949). Thus, our results demonstrated that MLVA could identify clinical isolates that could not be distinguished by ompA typing.
