Ehrlichia chaffeensisInfection in Dogs in South Korea

Vector-Borne and Zoonotic Diseases, 2008
Ehrlichia chaffeensis is one of the causative agents of canine ehrlichiosis and human monocytic ehrlichiosis (HME). Canine ehrlichiosis caused by E. chaffeensis was diagnosed in two dogs in South Korea based on clinical findings, and the diagnosis was confirmed by polymerase chain reaction (PCR) and DNA sequencing. A 5-year-old intact male American Pit

Increased Incidence of Ehrlichia chaffeensis Infections in the United States, 2012 Through 2016.

Vector Borne and Zoonotic Diseases, 2020
Human ehrlichioses are tick-borne diseases that have been increasing in incidence in the United States during recent years. Ehrlichia chaffeensis is one of the primary bacteria that cause ehrlichiosis in humans, which typically results in fever-like ...

SUSCEPTIBILITY OF RED AND GRAY FOXES TO INFECTION BY EHRLICHIA CHAFFEENSIS

Journal of Wildlife Diseases, 1999
Red foxes (Vulpes vulpes) and gray foxes (Urocyon cinereoargenteus) were evaluated for their susceptibility to experimental infection with Ehrlichia chaffeensis, the causative agent of human monocytotropic ehrlichiosis. Two red foxes and three gray foxes were inoculated intravenously with E.

Prevalence ofEhrlichia chaffeensisandEhrlichia ewingiiin Ticks from Tennessee

Vector-Borne and Zoonotic Diseases, 2010
Human ehrlichiosis is the second most common tick-borne disease reported in Tennessee after Rocky Mountain spotted fever. Two closely related ehrlichiae, Ehrlichia chaffeensis and Ehrlichia ewingii, are both causative agents of human disease and are transmitted by Amblyomma americanum, the lone star tick.

Ehrlichia chaffeensis in Archived Tissues of a White-tailed Deer

Journal of Wildlife Diseases, 1999
White-tailed deer (Odocoileus virginianus) play an integral role in the natural history of Ehrlichia chaffeensis, the causative agent of human monocytic ehrlichiosis (HME). Paraffinized tissues from a white-tailed deer submitted as a diagnostic case to the Southeastern Cooperative Wildlife Disease Study (Athens, Georgia, USA) in October of 198.5 and ...

Molecular Pathogenesis ofEhrlichia chaffeensisInfection

Annual Review of Microbiology, 2015
Ehrlichia chaffeensis is an obligatory intracellular and cholesterol-dependent bacterium that has evolved special proteins and functions to proliferate inside leukocytes and cause disease. E. chaffeensis has a multigene family of major outer membrane proteins with porin activity and induces infectious entry using its entry-triggering protein to bind ...

Ehrlichia chaffeensis, a new species associated with human ehrlichiosis

Journal of Clinical Microbiology, 1991
The bacterial 16S rRNA genes from blood samples of two patients with human ehrlichiosis and from an isolate recovered from one of the patients were amplified by using the polymerase chain reaction. The amplimers were then cloned and sequenced. The 16S rRNA gene sequence was also determined for Ehrlichia canis (two strains), E. equi, E.

Persistent infection of C3H/HeJ mice by Ehrlichia chaffeensis

Veterinary Microbiology, 1996
Description of the pathobiology of the recently described zoonotic agent of human ehrlichiosis (Ehrlichia chaffeensis) would be greatly facilitated by the availability of a convenient experimental animal model of infection. We determined whether C3H/HeJ mice could sustain persistent infection by this predominantly monocyte-inhabiting rickettsia.

Human ehrlichiosis: Hematopathology and immunohistologic detection of Ehrlichia chaffeensis

Human Pathology, 1993
Human ehrlichiosis is a recently described zoonosis caused by a rickettsia that infects leukocytes. Most patients have fever, headache, chills, and myalgias and develop leukopenia, thrombocytopenia, anemia, and elevations in serum hepatic aminotransferases. The cause of the peripheral leukopenia and thrombocytopenia is not known.
