چکیده انگلیسی
Tick-borne infections are responsible for many emerging diseases in humans and several vertebrates. These include human infections with Anaplasma phagocytophilum, Ehrlichia chaffeensis, and Ehrlichia ewingii. Because single or co-infections can result from tick bites, the availability of a rapid, multiplex molecular test will be valuable for timely diagnosis and treatment. Here, we describe a multiplex molecular test that can detect single or co-infections with up to five Ehrlichia and Anaplasma species. The test protocol includes the magnetic capture-based purification of 16S ribosomal RNA, its enrichment, and specific-pathogen(s) detection by real-time reverse transcriptase-polymerase chain reaction. We also report a unique cloning strategy to develop positive controls in the absence of a pathogen's genomic DNA. The test was assessed by examining blood samples from dogs suspected to be positive for ehrlichiosis. The dog was chosen as the model system because it is susceptible to acquire infections with up to five pathogens of the genera Ehrlichia and Anaplasma. The test identified single infections in the canine host with E. chaffeensis, E. canis, E. ewingii, A. phagocytophilum, and A. platys and co-infection with E. canis and A. platys. The multipathogen detection and novel positive control development procedures described here will be valuable in monitoring infections in people, other vertebrates, and ticks.
