A real-time PCR assay was developed for the detection of Ehrlichia chaffeensis. The assay is species specific and provides quantitative results in the range 10 to 1010 gene copies. The assay is not inhibited by the presence of tick, human, or mouse DNA and is compatible with high sample throughput. The assay was compared with previously described assays for E. chaffeensis.
