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 ...

Ehrlichia chaffeensis in Child, Venezuela

Emerging Infectious Diseases, 2008
To the Editor: Human monocytic ehrlichiosis is a tick-borne infectious disease caused by Ehrlichia chaffeensis (1). Serologic studies have indicated E. chaffeensis infection in Latin American countries: Venezuela (2), Mexico (3), Argentina (4), Chile (5), and Brazil (6). However, no molecular evidence for E. chaffeensis has been reported.

Naturally Occurring Ehrlichia chaffeensis Infection in Coyotes from Oklahoma [PDF]

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

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 ...

Experimental Ehrlichia chaffeensis infection in beagles [PDF]

Journal of Medical Microbiology, 2003
A canine model for human monocytic ehrlichiosis was used to assess persistent infection and antigenic variation of Ehrlichia chaffeensis. Two beagle dogs were infected subcutaneously with E. chaffeensis Arkansas strain. The dogs were observed for 6 months after inoculation for clinical signs, blood chemistry changes, antibodies to E.

Comparative Analysis of Genome of Ehrlichia sp. HF, a Model Bacterium to Study Fatal Human Ehrlichiosis

BMC Genomics, 2021
Background The genus Ehrlichia consists of tick-borne obligatory intracellular bacteria that can cause deadly diseases of medical and agricultural importance. Ehrlichia sp. HF, isolated from Ixodes ovatus ticks in Japan [also referred to as I.

Ultrastructural variation of cultured Ehrlichia chaffeensis [PDF]

Journal of Medical Microbiology, 1995
The ultrastructure of Ehrlichia chaffeensis (Arkansas strain) was studied in non-irradiated and irradiated monolayers of mouse embryo, Vero, BGM and L929 cells, and in non-irradiated DH82 cells. Within the intracellular parasitophorous vacuoles (morulae), two types of ehrlichial cells were found regularly--those with uniformly dispersed nucleoid ...
