Ehrlichia spp. close to Ehrlichia ruminantium, Ehrlichia canis, and “Candidatus Ehrlichia regneryi” linked to heartwater-like disease in Kenyan camels (Camelus dromedarius)

Tropical Animal Health and Production, 2021
We present findings from an outbreak of a heartwater-like disease in camels that killed at least 2000 adult animals in Kenya in 2016. Clinical signs included excitability, head pressing, aimless wandering, recumbency, and fast breathing followed by death after about 4 days. The observed morbidity in one herd was 40% with an average mortality of 7.5% in

Reorganization of genera in the families Rickettsiaceae and Anaplasmataceae in the order Rickettsiales: unification of some species of Ehrlichia with Anaplasma, Cowdria with Ehrlichia and Ehrlichia with Neorickettsia, descriptions of six new species combinations and designation of Ehrlichia equi and 'HGE agent' as subjective synonyms of Ehrlichia phagocytophila. [PDF]

International Journal of Systematic and Evolutionary Microbiology, 2001
The genera Anaplasma, Ehrlichia, Cowdria, Neorickettsia and Wolbachia encompass a group of obligate intracellular bacteria that reside in vacuoles of eukaryotic cells and were previously placed in taxa based upon morphological, ecological, epidemiological and clinical characteristics.

Diversity unearthed by the estimated molecular phylogeny and ecologically quantitative characteristics of uncultured Ehrlichia bacteria in Haemaphysalis ticks, Japan

Scientific Reports, 2021
Ehrlichia species are obligatory intracellular bacteria transmitted by arthropods, and some of these species cause febrile diseases in humans and livestock.

Seroprevalence of Ehrlichia canis and of Canine Granulocytic Ehrlichia Infection in Dogs in Switzerland [PDF]

Journal of Clinical Microbiology, 1998
ABSTRACT Serum samples from 996 dogs in Switzerland were examined for antibodies to Ehrlichia canis and to the agent causing canine granulocytic ehrlichiosis (CGE). Ehrlichiosis, borreliosis, and systemic illness not associated with ticks were suspected in 75, 122, and 157 of these dogs, respectively.

Glycosylation of Homologous Immunodominant Proteins of Ehrlichia chaffeensis and Ehrlichia canis [PDF]

Infection and Immunity, 2000
ABSTRACT The glycoprotein genes of Ehrlichia chaffeensis (1,644 bp) and Ehrlichia canis (2,064 bp) encode proteins of 548 to 688 amino acids with predicted molecular masses of only 61 and 73 kDa but with electrophoretic mobilities of 120 kDa (P120) and 140 kDa (P140), respectively ...

Molecular prevalence of emerging Anaplasma and Ehrlichia pathogens in apparently healthy dairy cattle in peri-urban Nairobi, Kenya

BMC Veterinary Research, 2020
Background Anaplasma and Ehrlichia species are tick-borne pathogens of both veterinary and public health importance. The current status of these pathogens, including emerging species such as Ehrlichia minasensis and Anaplasma platys, infecting cattle in ...

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

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.

Journal of Veterinary Internal Medicine, 2000
Ehrlichia canis, E equi, andE risticiiseroprevalence was determined by microimmunofluorescent antibody testing (IFA) in a sequential population of 1,845 sick dogs admitted during a 1‐year period to the North Carolina State University Veterinary Teaching Hospital.
