Figure 2From: Detection of Chlamydia trachomatis-DNA in synovial fluid: evaluation of the sensitivity of different DNA extraction methods and amplification systemsResults of PCR analysis of Chlamydia trachomatis EB in synovial samples following DNA extraction by (a) alkaline lysis and (b) Chelex®. On the y-axes concentration of Chlamydia trachomatis elementary bodies (EB)/ml are given. Each point on the graph indicates the detection limit of one serial dilution analysis. Numbers in boxes represent lowest reproducible detection limit of Chlamydia trachomatis EB/ml in synovial fluid.Back to article page
