Understanding the long-lasting associations among humans, neglected dogs, tick-borne diseases, and core blood bacteria-related pathogenic taxa using next-generation sequencing [PDF]

International Journal of One Health
Background and Aim: Dogs are long-lasting companion animals, and ticks are the most common external parasites in dogs. An increase in the population of neglected domestic dogs has increased the risk of contact with ticks, especially in places where tick ...

The glycoprotein TRP36 of Ehrlichia sp. UFMG-EV and related cattle pathogen Ehrlichia sp. UFMT-BV evolved from a highly variable clade of E. canis under adaptive diversifying selection

Parasites & Vectors, 2014
Background A new species of Ehrlichia, phylogenetically distant from E. ruminantium, was found in 2010 infecting cattle in Canada. In 2012 and 2013, we reported the in vitro propagation, molecular and ultrastructural characterization of Ehrlichia sp ...

Ehrlichia ruminantium, Sudan

Emerging Infectious Diseases, 2005
To the Editor: Ehrlichia ruminantium, the causative agent of heartwater, is transmitted by Amblyomma spp. ticks. Amblyomma variegatum ticks, which are found in the Caribbean and sub-Saharan Africa, except in certain areas of southern Africa, are major vectors of E. ruminantium (1–3). A.

The super repertoire of type IV effectors in the pangenome of Ehrlichia spp. provides insights into host-specificity and pathogenesis.

PLoS Computational Biology, 2021
The identification of bacterial effectors is essential to understand how obligatory intracellular bacteria such as Ehrlichia spp. manipulate the host cell for survival and replication. Infection of mammals-including humans-by the intracellular pathogenic

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 ...

Exit mechanisms of the intracellular bacterium Ehrlichia. [PDF]

PLoS ONE, 2010
The obligately intracellular bacterium Ehrlichia chaffeensis that resides in mononuclear phagocytes is the causative agent of human monocytotropic ehrlichiosis. Ehrlichia muris and Ixodes ovatus Ehrlichia (IOE) are agents of mouse models of ehrlichiosis.
