Detection of Chlamydia trachomatis in endocervical smears of sexually active women in Manaus-AM, Brazil, by PCR

RESUMO

Chlamydia trachomatis is now one of the most prevalent bacteria found in classic sexually transmissible diseases (STD), and as such, constitutes a serious public health problem. We examined the prevalence of Chlamydia trachomatis, by polymerase chain reaction (PCR), in 121 sexually active women who sought treatment for STD in the Alfredo da Matta Institute of Dermatology and Venerology and the Institute of Tropical Medicine of Amazonas in Manaus, Brazil. These women were examined by a specific PCR for the chlamydial plasmid, and the nature of the amplicon was determined by restriction analysis and DNA sequencing. The PCR diagnosis revealed a prevalence of 20.7 percent infected women
