Our aims were to genotype Chlamydia trachomatis strains present in urogenital samples and to investigate the occurrence of the Swedish new variant of C. trachomatis in Finland. We genotyped 160 C. trachomatis positive samples with ompA real-time PCR and analyzed 495 samples for the new variant. The three most prevalent genotypes were E (40%), F (28%), and G (13%). Only two specimens containing bacteria with the variant plasmid were detected. It seems that in Finland the percentage of infections due to genotypes F and G has slightly increased during the last 20 years. Genotypes E and G appear to be more common, and genotypes J/Ja and I/Ia appear to be less common in Europe than in the USA. Although the genotype E was the most common genotype among C. trachomatis strains, the new variant was rarely found in Finland.
我们的目的是对泌尿生殖系统样本中存在的沙眼衣原体菌株进行基因分型，并调查芬兰沙眼衣原体瑞典新变种的出现情况。我们使用ompA实时聚合酶链反应对160份沙眼衣原体阳性样本进行基因分型，并对495份样本进行新变种分析。三种最常见的基因型是E（40%）、F（28%）和G（13%）。仅检测到两份含有携带变异质粒细菌的标本。在芬兰，过去20年中由基因型F和G引起的感染百分比似乎略有增加。在欧洲，基因型E和G似乎更为常见，而基因型J/Ja和I/Ia似乎比在美国少见。虽然基因型E是沙眼衣原体菌株中最常见的基因型，但在芬兰很少发现新变种。
