In this study, we genotyped<jats:italic>C. trachomatis<\/jats:italic>strains from urine or endocervical specimens collected from 163<jats:italic>C. trachomatis<\/jats:italic>-positive female and male youths, and female adults, residing in two different regions of Brazil, the city of Goi\u00e2nia located in the central part of Brazil, and the city of Vit\u00f3ria in the south-east region.<jats:italic>C. trachomatis<\/jats:italic>strains were genotyped by amplifying and sequencing the<jats:italic>ompA<\/jats:italic>gene encoding the chlamydial major outer-membrane protein, which is genovar specific. We found nine different<jats:italic>C. trachomatis<\/jats:italic>genovars: E (39.3\u200a%), F (16.6\u200a%), D (15.9\u200a%), I (8.6\u200a%), J (7.4\u200a%), G (4.9\u200a%), K (3.1\u200a%), H (2.4\u200a%) and B (1.8\u200a%). The distribution of the<jats:italic>C. trachomatis<\/jats:italic>genovars in the two regions of Brazil was similar, and there was no statistically significant association of serovars with age, gender, number of sexual partners or clinical symptoms. The overall distribution of<jats:italic>C. trachomatis<\/jats:italic>genovars in Brazil appears similar to that found in other regions of the world, where E, D and F are the most common. This supports the notion that, during the last few decades, the overall distribution of<jats:italic>C. trachomatis<\/jats:italic>genovars throughout the world has been relatively stable.<\/jats:p>","DOI":"10.1099\/jmm.0.026476-0","type":"journal-article","created":{"date-parts":[[2010,12,24]],"date-time":"2010-12-24T03:21:36Z","timestamp":1293160896000},"page":"472-476","source":"Crossref","is-referenced-by-count":29,"title":["Distribution of Chlamydia trachomatis genovars among youths and adults in Brazil"],"prefix":"10.1099","volume":"60","author":[{"given":"Ana C.
