Novel Ehrlichia sp. detected in Magellanic penguins (Sphenicus magellanicus) and in the seabird tick Ixodes uriae from Magdalena Island, southern Chile.

Ticks and Tick-borne Diseases, 2019
Ehrlichia spp. are obligatory intracellular microorganisms that infect hematopoietic, endothelial or blood cells of mammals. Ticks are the only vectors of these agents in nature.

Prevalence, molecular characterization and risk factor analysis of Ehrlichia canis and Anaplasma platys in domestic dogs from Paraguay.

Comparative Immunology, Microbiology & Infectious Diseases, 2019
This is the first study to investigate the prevalence and risk factors associated with Ehrlichia canis and Anaplasma platys positivity in dogs from Paraguay. Conventional PCR assays for the E. canis 16SrRNA gene and A. platys p44 gene were carried out in

Studies on Ehrlichia canis

Zentralblatt für Veterinärmedizin Reihe B, 2010
Summary The pathological anatomical findings are described in 10 dogs experimentally infected with Ehrlichia canis. The brains were characterized by endothelial, perivascular and glial proliferations, lymphoplasmacellular meningo-panencephalitis and chorioiditis.

A putative novel strain of Ehrlichia infecting Amblyomma tigrinum associated with Pampas fox (Lycalopex gymnocercus) in Esteros del Iberá ecoregion, Argentina.

Ticks and Tick-borne Diseases, 2019
The current work evaluated road-killed Pampas foxes (Lycalopex gymnocercus) and their ticks for the presence of vector-borne agents in the ecoregion Esteros del Iberá in northeastern Argentina.

Ultrastructure of Ehrlichia mineirensis, a new member of the Ehrlichia genus

Veterinary Microbiology, 2013
Recently, we reported the in vitro isolation and the molecular characterization of a new species of Ehrlichia (Ehrlichia mineirensis) from haemolymph of Brazilian Rhipicephalus (Boophilus) microplus ticks. This organism shows an ortholog of Ehrlichia canis major immunogenic protein gp36 with a new structure of tandem repeats.

Molecular identification of vector-borne organisms in Ehrlichia seropositive Nicaraguan horses and first report of Rickettsia felis infection in the horse.

Acta Tropica, 2019
Certain vector-borne organisms serve as etiological agents of equine disease. After previously identifying a new Ehrlichia species in horses from Mérida, we aimed to determine the infection frequency and screen for a wide range of vector-borne organisms ...

Genetic diversity of Anaplasma and Ehrlichia bacteria found in Dermacentor and Ixodes ticks in Mongolia.

Ticks and Tick-borne Diseases, 2019
Anaplasma and Ehrlichia are tick-borne bacterial pathogens that cause human granulocytic anaplasmosis, human monocytic ehrlichiosis, and are severe threats to livestock economies like Mongolia. In this study, ticks were collected, identified, and pooled (

Molecular and Serological Prevalence of Anaplasma phagocytophilum, A. platys, Ehrlichia canis, E. chaffeenses, E. ewingii, Borrelia burgdorferi, Babesia canis, B. gibsoni and B. vogeli among Clinically Healthy Outdoor Dogs in Serbia.

Veterinary Parasitology: Regional Studies and Reports, 2018
Data concerning combined molecular and serological prevalence of emerging canine tick-borne pathogens in Serbia are lacking. A large population of outdoor living dogs in Belgrade, Serbia's' capital, present an excellent population for epidemiology study.
