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.

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

Ehrlichia Infection in Italy [PDF]
Emerging Infectious Diseases, 1998 Immunoglobulin M seroconversion to Ehrlichia chaffeensis was documented in U.S. citizens bitten by ticks in Sardinia. Seven cases of suspected ehrlichiosis in local residents were not confirmed by laboratory tests. In Alpine areas antibodies to E. phagocytophila were detected in persons at high risk, i.e., foresters (8.6%) and hunters (5.5%), and in ...

EDIS, 2021 Ehrlichia and Anaplasma are bacteria that cause diseases, known as ehrlichiosis and anaplasmosis, in humans and other animals. Ehrlichia and Anaplasma are primarily transmitted through the bites of infected hard ticks, such as the lone star tick, the blacklegged tick, and the American dog tick.

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.

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

Detection of Antibodies to Ehrlichia spp. in Dromedary Camels and Co-Grazing Sheep in Northern Kenya Using an Ehrlichia ruminantium Polyclonal Competitive ELISA [PDF]
, 2022 A disease with clinical and post-mortem presentation similar to those seen in heartwater, a tick-borne disease of domestic and wild ruminants caused by the intracellular bacterium Ehrlichia ruminantium, was first reported in dromedary camels in Kenya in ...
