title: [Serovar distributions of cervical Chlamydia trachomatis isolated in Nagano Prefecture].
abstract: Between 1992 and 1998, serotyping of 82 Chlamydia trachomatis cervical isolates were examined by micro-IF method in Nagano Prefecture. Of these, 17 isolates (20.7%) were serovar E, 15 (18.3%) were serovar F, 14 (17.1%) were serovar D and 10 (12.2%) were serovar G, and the isolates typed these serovars were found to be 68.3% whole. Furthermore, serovars B (7.3%) and K (9.8%) were comparatively frequently found. From 1992 to 1994, the number of isolates of B-complex, intermediate and C-complex were 18, 17 and 6, respectively. On the other hand, from 1995 to 1998, the number of the isolates were 19, 8 and 14, respectively. The distribution of serovars of C. trachomatis tended to fluctuate from serovars D and E to F and G as the patients grew older. Moreover, serovar E isolates were only detected from patients less than 40 years old. Although most of the serovar I isolates were detected from the patients with vaginal discharge, the other isolates did not clearly indicate the relationship of serovars and clinical symptoms.
