Ehrlichiosis is the general name used to describe diseases caused by the bacteria Ehrlichia chaffeensis, E. ewingii, or E. muris eauclairensis in the United States. These bacteria are spread to people primarily through the bite of infected ticks including the lone star tick (Amblyomma americanum) and the blacklegged tick (Ixodes scapularis).
Ehrlichia ewingii will cause Human Granulocytic Ehrlichiosis by invading white blood cells known as granulocytes. The immune system will destroy infected cells in response to the infection causing disease symptoms.
3 While treatment is similar, clinical pathology findings can vary dramatically between dogs with ehrlichiosis; though, thrombocytopenia and mild anemia are Using Ehrlichia species‐specific peptides, recent studies indicate that E. ewingii is the most seroprevalent tick‐transmitted Ehrlichia spp. affecting dogs in the United States. 9-11 The primary vector for E. ewingii is Amblyomma americanum, an aggressive tick that feeds on multiple reservoir hosts, including white‐tailed deer, reptiles, birds, and dogs. 12 In contrast, Ehrlichia canis Ehrlichia ewingii will cause Human Granulocytic Ehrlichiosis by invading white blood cells known as granulocytes. The immune system will destroy infected cells in response to the infection causing disease symptoms. Abstract. Two closely related zoonotic ehrlichiae, Ehrlichia chaffeensis and E. ewingii, are transmitted by Amblyomma americanum, the lone star tick.Because white-tailed deer (Odocoileus virginianus) are critical hosts for all mobile stages of A. americanum and are important vertebrate reservoirs of E. chaffeensis, we investigated whether deer may be infected with E. ewingii, a cause of Ehrlichia ewingii belongs to a group of organisms in the family Anaplasmataceae, a group that also includes the tick-borne pathogens Ehrlichia chaffeensis and Anaplasma phagocytophilum.

nov., the etiologic agent of canine granulocytic ehrlichiosis. We conclude that E. ewingii is the predominant etiologic agent of canine ehrlichiosis in the areas of Missouri included in this survey. E. canis, a widely recognized agent of canine ehrlichiosis, was not detected in any animal.
Human Ewingii Ehrlichiosis Last Updated: January 2013 a result, the names of some diseases also changed. For instance, equine granulocytic Importance Ehrlichiosis and anaplasmosis are tick-borne diseases caused by obligate intracellular bacteria in the genera Ehrlichia and …
E. ewingii was initially thought to be a canine pathogen, until a series of four human cases was described in 1999 ( Buller et al., 1999 ). The epidemiology of HEE remains poorly defined due to the lack of a specific serological assay for this organism and the absence of a dedicated reporting system for this infection.

by Amblyomma americanum, E. ewingii is the most seroprevalent canine Ehrlichia spp. in North America, predominantly in the Southern and Midwestern United States. 2, 12 It infects granulocytes, and clinicopathologic abnormalities reported in dogs with canine granulocytic ehrlichiosis include fever, lameness, Another type of ehrlichiosis, called canine granulocytic ehrlichiosis (CGE), is caused by infection with Ehrlichia ewingii bacteria, which are typically transmitted through the bites of lone star ticks (Amblyomma americanum). Lone star ticks are primarily found in the Eastern, Southeastern, and Midwestern parts of the United States.

In addition to Ehrlichia muris andCowdria ruminantium, the E. canis genogroup contains three species that are known to infect dogs: E. canis, Ehrlichia ewingii, and Ehrlichia chaffeensis . Although natural infection with C. ruminantium has not been reported, when dogs were experimentally infected, they developed no clinical abnormalities but remained PCR positive for periods up to 3 weeks ( 22 ).
