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

Microbiome Composition of Haemaphysalis flava in Korea and Diversity Analysis Based on Region, Developmental Stage, and Sex

Entomological Research, Volume 55, Issue 3, March 2025.
ABSTRACT Ticks are well‐known vectors of various diseases and are widely distributed globally. In this study, we investigated the microbial community of Haemaphysalis flava, a common tick species in Korea, using 16S rRNA gene analysis. Alpha diversity analysis revealed that adult ticks had higher microbial richness and complexity than nymphs, and the ...

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 ...

ERLIQUIOSE CANINA EM CAMPOS DOS GOYTACAZES, RIO DE JANEIRO, BRASIL

Ciência Animal Brasileira, 2007
Com o propósito de pesquisar a positividade e analisar os aspectos hematológicos de cães infectados com Ehrlichia spp. na cidade de Campos dos Goytacazes, avaliaram-se 1.576 cães. Realizaram-se pesquisa de hemocitozoários e hemograma para se determinar a

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

Prevalence of canine Babesia and Ehrlichia co-infection and the predictive value of haematology

Onderstepoort Journal of Veterinary Research, 2018
Canine babesiosis and ehrlichiosis are important tick-borne infections in South Africa. Many South African general veterinary practitioners perceive co-infection with Ehrlichia spp. as a common occurrence in dogs with babesiosis.

Ehrlichia-Infected Ticks on Migrating Birds

Emerging Infectious Diseases, 2001
During the spring of 1996, an estimated 581,395 Ehrlichia-infected ticks were imported into Sweden by migrating birds. Ehrlichia gene sequences found in ticks collected from these migrating birds were identical to those of granulocytic ehrlichiosis found in domestic animals and humans in Sweden.

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.
