Ehrlichia chaffeensis, the causative agent of HME, was detected by nested PCR in just five (0.64%) I. pacificus ticks and four (6.9%) D. variabilis ticks. Interestingly, eight (1.03%) I. pacificus ticks were co-infected with B. burgdorferi and A. phagocytophilum, and just one (0.12%) tick was co-infected with B. burgdorferi and E. chaffeensis.

Ehrlichia chaffeensis, a new species associated with human ehrlichiosis 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.

Ehrlichia chaffeensis

Account Login. Patient Ehrlichia species may infect granulocytes or monocytes in some hosts. Currently, the genus Ehrlichia contains five recognized species: E. canis, E. chaffeensis, E. ewingii, E. muris and E. ruminantium. E. canis causes canine monocytic ehrlichiosis (CME). This organism has been implicated rarely in human illness.

Etymology: N.L. masc./fem. adj. chaffeensis, pertaining to Fort Chaffee in western Arkansas, where the patient from whom the first isolate was prepared was identified. Gender: feminine.

Nov 26, 1999 Since its first description in human beings in 1986, ehrlichiosis is now increasingly recognized as a cause of tick-borne febrile illnesses.

The two known primary agents of human ehrlichiosis are E. chaffeensis and E. ewingii. (A third species, E. canis, has recently been found to infect humans, but its significance as a human pathogen is not well understood at this point.) Se hela listan på Background Anaplasmosis, caused by Anaplasma phagocytophilum and Anaplasma platys, and ehrlichiosis, caused by Ehrlichia chaffeensis, Ehrlichia ewingii, the "Panola Mountain Ehrlichia" and Ehrlichia muris- like pathogens have been identified as emerging tick borne infectious diseases in dogs and human patients.

Ehrlichia chaffeensis infects mononuclear phagocytes and survives intracellularly by exploiting host cell processes to evade host defenses. The mechanisms involved are not fully defined, but appear to rely largely on a subset of tandem repeat proteins (TRP) effectors. E. chaffeensis TR …

Whereas Ehrlichia chaffeensis (HME) often causes meningoencephalitis, this is rare with Anaplasma phagocytophilum infection. [] Case Presentation: A 47year old Caucasian man came to the emergency room with of fever, severe headaches, severe body aches and pain for 4days. Headaches worsened and he developed photophobia on day 5. 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 the human cell surface protein DNase X. Two forms, human monocytic ehrlichiosis (HME) and human granulocytic ehrlichiosis (HGE), have been described.

Ehrlichia chaffeensis. Ehrlichia chaffeensis is transmitted to humans by the lone star tick, Amblyomma americanum (see Figures 4 and 5 below). The lone star tick is among the most commonly encountered ticks in the southeastern United States, with a range that extends into areas of the Midwest and New England states.

(14, 15) Ehrlichiosis spreads through infected tick bites. The lone star tick, or Amblyomma americanum, is the primary vector of E. chaffeensis and E. ewingii.The deer tick, otherwise known as Ixodes Ehrlichia is a genus of Rickettsiales bacteria that are transmitted to vertebrates by ticks. These bacteria cause the disease ehrlichiosis, which is considered zoonotic, because the main reservoirs for the disease are animals.

Ehrlichia chaffeensis is an obligate intracellular, Gram-negative species of Rickettsiales bacteria.
