New data on infection of Haemaphysalis concinna with tick-borne infection agents in humans and animals in the territory of Baikal region

Acta Biomedica Scientifica
Background. In recent years, the tick Haemaphysalis concinna has drawn increased attention from researchers due to its expanding geographic range and its growing role in the transmission of diseases of various etiologies to humans and animals.

Potentially Novel Ehrlichia Species in Horses, Nicaragua

Emerging Infectious Diseases, 2015
Ehrlichia sp. DNA was amplified from 4 Ehrlichia-seroreactive horses from Mérida, Nicaragua. Sequencing of 16S rDNA, sodB, and groEL genes indicated that the bacterium is most likely a novel Ehrlichia species. The tick vector and the potential for canine

Ehrlichia type IV secretion system effector Etf-2 binds to active RAB5 and delays endosome maturation

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Phagocytosis and subsequent destruction of pathogens when the phagosomes in which they reside are fused with lysosomes are pillars of the eukaryotic innate immune defense.

Ehrlichia and Anaplasma in Florida

EDIS, 2012
Ehrlichia and Anaplasma are related bacterial genera containing species that can cause disease in both humans and domestic animals. The diseases are often referred to simply as ehrlichiosis or anaplasmosis, but there are multiple species of bacteria that can cause different disease symptoms and have different vectors. This revised 3-page fact sheet was

Detection of a putative novel genotype of Ehrlichia sp. from opossums (Didelphis aurita) from Brazil.

Revista brasileira de parasitologia veterinaria = Brazilian journal of veterinary parasitology : Orgao Oficial do Colegio Brasileiro de Parasitologia Veterinaria, 2019
Erlichiosis affects humans and animals worldwide. Its distribution and prevalence depends on the presence of tick vectors and hosts in one geographic area. The aim of the present study was to investigate the occurrence of Ehrlichia spp. and Anaplasma spp.

Emerging tick-borne infections in mainland China: an increasing public health threat [PDF]

, 2015
Since the beginning of the 1980s, 33 emerging tick-borne agents have been identified in mainland China, including eight species of spotted fever group rickettsiae, seven species in the family Anaplasmataceae, six genospecies in the complex Borrelia ...

Antigenic protein modifications in Ehrlichia

Parasite Immunology, 2009
SUMMARY To develop effective vaccination strategies against Ehrlichia, we have previously reported developing an animal model of cross‐protection in which C57BL/6 mice primed with E. muris were resistant to lethal infection with Ixodes ovatus ehrlichia (IOE). Polyclonal antibody produced in mice after priming with E.

Uncommon Ehrlichia canis infection associated with morulae in neutrophils from naturally infected dogs in Brazil.

Transboundary and Emerging Diseases, 2019
Ehrlichia and Anaplasma species are the most common tick-borne disease (TBD) pathogens in dogs worldwide. Ehrlichia canis, the aetiological agent of the Canine Monocytic Ehrlichiosis (CME), is known to replicate within the cytoplasm of mononuclear cells ...

RipE expression correlates with high ATP levels in Ehrlichia, which confers resistance during the extracellular stage to facilitate a new cycle of infection

Frontiers in Cellular and Infection Microbiology
Ehrlichiosis is a potentially life-threatening disease caused by infection with the obligatory intracellular bacteria Ehrlichia species. Ehrlichia japonica infection of mice provides an animal model of ehrlichiosis as it recapitulates full-spectrum and ...

A new TaqMan method for the reliable diagnosis of Ehrlichia spp. in canine whole blood

Parasites & Vectors, 2018
Ehrlichiosis is an important emerging infectious disease of the canid family and humans worldwide. To date, no extensive evaluation or validation of a molecular diagnostic test for ehrlichiosis has been published.
