Development of a generic Ehrlichia FRET-qPCR and investigation of ehrlichioses in domestic ruminants on five Caribbean islands

Parasites & Vectors, 2015
Background The Ehrlichia are obligate intracellular Gram-negative tick-borne bacteria that are important human and animal pathogens. There is a need for assays to rapidly and reliably detect and differentiate the five generally recognized species into ...

Canine Ehrlichiosis Caused Simultaneously by Ehrlichia canis and Ehrlichia platys [PDF]

Microbiology and Immunology, 2000
AbstractTo identify the causative agent of canine ehrlichiosis that has occurred in the suburbs of Guangzhou, China, since 1998, the 16S rRNA gene was amplified and sequenced. Two sequences of 1,482 and 1,483 base pairs were obtained and named as Gzh981 and Gzh982, respectively.

High prevalence of a host‐associated Anaplasma lineage in wild coatis (Nasua nasua) from the Brazilian Atlantic Forest

Medical and Veterinary Entomology, EarlyView.
Anaplasma sp. DNA was detected in 47.9% of free‐ranging coatis (Nasua nasua) sampled in Iguaçu National Park, southern Brazil. Molecular analyses revealed a genetically distinct Anaplasma lineage infecting coatis, differing from Anaplasma strains detected in associated tick populations.
