Cryptic plasmid chlamydia trachomatis

WebRole of Cryptic Plasmid. Most Chlamydiae isolates possess a 7.4 kbp cryptic plasmid designated pCT. This extrachromosomal genetic element was first isolated by Palmer and Falkow in 1986 . This cryptic plasmid was found in laboratory strains of all C. trachomatis serovars that cause human infection as well as in 200 separate clinical isolates. WebChlamydia trachomatis is the most common sexually transmitted pathogen globally, causing serious health problems and representing a burden on public health. A new variant of C. trachomatis (nvCT) that carries mutations (C1514T, C1515T and G1523A) in the 23S rRNA gene has eluded detection in Aptima Combo 2 assays.
