A real-time PCR assay for detection of the Ehrlichia muris-like agent, a newly recognized pathogen of humans in the upper Midwestern United States.

ABSTRACT: The Ehrlichia muris-like agent (EMLA) is an emerging, tick-transmitted human pathogen that occurs in the upper Midwestern United States. Here, we describe the development and validation of a p13-based quantitative real-time PCR TaqMan assay to detect EMLA in blood or tissues of ticks, humans, and rodents. The primer and probe specificities of the assay were ascertained using a large panel of various Ehrlichia species and other members of Rickettsiales. In addition to control DNA, both non-infected and EMLA-infected human blood, Mus musculus blood, and M. musculus tissue extracts were evaluated, as were non-infected and EMLA-infected Ixodes scapularis and uninfected Dermacentor variabilis DNA lysates. The specificity of the probe was determined via real-time PCR. An EMLA p13 control plasmid
