Human Case of Ehrlichia chaffeensis Infection, Taiwan [PDF]

Emerging Infectious Diseases, 2019
In 2018, an immunosuppressed woman in southern Taiwan had onset of fever, chills, myalgia, malaise, thrombocytopenia, lymphocytopenia, and elevated hepatic transaminases. Investigation revealed infection with Ehrlichia chaffeensis.

Proteomic analysis of the Ehrlichia chaffeensis phagosome in cultured DH82 cells. [PDF]

PLoS ONE, 2014
Ehrlichia chaffeensis is an obligately intracellular bacterium that resides and multiplies within cytoplasmic vacuoles of phagocytes. The Ehrlichia-containing vacuole (ECV) does not fuse with lysosomes, an essential condition for Ehrlichia to survive ...

Seroprevalence of Ehrlichia canis, Ehrlichia chaffeensis and Ehrlichia ewingii in dogs in North America [PDF]

Parasites & Vectors, 2012
This study evaluated the exposure of dogs to three different Ehrlichia spp. in the south and central regions of the United States where vector-borne disease prevalence has been previously difficult to ascertain, particularly beyond the metropolitan areas.Dog blood samples (n = 8,662) were submitted from 14 veterinary colleges, 6 private veterinary ...

Aggregate-reactivation activity of the molecular chaperone ClpB from Ehrlichia chaffeensis. [PDF]

PLoS ONE, 2013
Rickettsiale diseases, including human monocytic ehrlichiosis caused by Ehrlichia chaffeensis, are the second leading cause of the tick-borne infections in the USA and a growing health concern. Little is known about how E.

Naturally Occurring Ehrlichia chaffeensis Infection in Two Prosimian Primate Species: Ring-tailed Lemurs (Lemur catta) and Ruffed Lemurs (Varecia variegata)

Emerging Infectious Diseases, 2002
A naturally occurring infection of Ehrlichia chaffeensis in lemurs is described. DNA of Ehrlichia chaffeensis was identified by polymerase chain reaction in peripheral blood from six of eight clinically ill lemurs.

Structure of thymidylate kinase fromEhrlichia chaffeensis [PDF]

Acta Crystallographica Section F Structural Biology and Crystallization Communications, 2011
The enzyme thymidylate kinase phosphorylates the substrate thymidine 5'-phosphate (dTMP) to form thymidine 5'-diphosphate (dTDP), which is further phosphorylated to dTTP for incorporation into DNA. Ehrlichia chaffeensis is the etiologic agent of human monocytotropic erlichiosis (HME), a potentially life-threatening tick-borne infection.

Ehrlichia chaffeensis Infection of Sika Deer, Japan

Emerging Infectious Diseases, 2009
To determine whether Ehrlichia chaffeensis exists in Japan, we used PCR to examine blood from sika deer in Nara, Japan. Of 117 deer, 36 (31%) were infected with E. chaffeensis. The E.

Transmission electron microscopy reveals distinct macrophage- and tick cell-specific morphological stages of Ehrlichia chaffeensis. [PDF]

PLoS ONE, 2012
Ehrlichia chaffeensis is an emerging tick-borne rickettsial pathogen responsible for human monocytic ehrlichiosis. Despite the induction of an active host immune response, the pathogen has evolved to persist in its vertebrate and tick hosts ...

Evidence of Ehrlichia chaffeensis in Argentina through molecular detection in marsh deer (Blastocerus dichotomus) [PDF]

International Journal for Parasitology: Parasites and Wildlife, 2019
Vector-borne pathogens are responsible for serious emerging diseases and have been widely described in wildlife. Ehrlichia chaffeensis causes the zoonotic “monocytic ehrlichiosis” in humans, is transmitted by the tick Amblyomma americanum and its ...

Naturally Occurring Ehrlichia chaffeensis Infection in Coyotes from Oklahoma

Emerging Infectious Diseases, 2000
A nested polymerase chain reaction assay was used to determine the presence of Ehrlichia chaffeensis, E. canis, and E. ewingii DNA in blood samples of free-ranging coyotes from central and north-central Oklahoma. Of the 21 coyotes examined, 15 (71%) were
