Ehrlichia chaffeensis shows resistance to several classes of antimicrobial agents in vitro that include fluoroquinolones (ciprofloxacin), chloramphenicol, macrolides and ketolides (erythromycin and telithromycin), sulpha-containing drugs (co-trimoxazole), β-lactams (penicillin) and aminoglycosides (gentamicin) [179,180].

A species of gram-negative bacteria that is the causative agent of human EHRLICHIOSIS. 2020-04-07 2019-01-20 Up to 1 in 3 people with ehrlichiosis report a rash; rash is more common in people with E. chaffeensis ehrlichiosis and generally occurs more often in children than adults. Rash usually develops 5 days after fever begins.

Ehrlichia chaffeensis

En art av gramnegativa bakterier (rickettsior) som orsakar ehrlichios hos människor. Den upptäcktes första gången hos infektionssjukdom kännetecknad av feber, huvudvärk, muskelvärk, anorexi och ibland hudutslag. Hos människa orsakas den av Ehrlichia chaffeensis, hos Ehrlichia chaffeensis. Förklaring. En art av gramnegativa bakterier som är orsakssambandet till human EHRLICHIOS.

Ehrlichia chaffeensis is an intracellular rickettsia-like bacterium that preferentially infects monocytes and is sequestered in parasitophorous vacuoles referred to as morulae. Infections with E chaffeensis are also referred to as human monocytotropic ehrlichiosis (HME). Ehrlichia chaffeensis causes a tick-borne disease affecting both animals and humans.

Ehrlichia chaffeensis are small, obligately intracellular, endosomal bacteria with tropism for macrophages. Persistent infection in reservoir white-tailed deer is transmitted by lone star ticks. Flu-like illness can progress to severe multisystem disease with toxic shock-like syndrome, meningitis, or ARDS. The case-fatality rate is 2.7%.

(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.)

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.

The case-fatality rate is 2.7%. A species of gram-negative bacteria that is the causative agent of human EHRLICHIOSIS. This organism was first discovered at Fort Chaffee, Arkansas, when blood samples from suspected human ehrlichiosis patients were studied.

Persistent intravascular infection with these bacteria is well documented in dogs ABSTRACT. Ehrlichia chaffeensis causes human monocytic ehrlichiosis, and its principal vector is the Amblyomma americanum tick.

It’s an uncommon illness that can affect people of all ages.

Se hela listan på mayoclinic.org 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 has been shown to survive for over a week in refrigerated blood. Therefore these bacteria may present a risk for transmission through blood transfusion and organ donation. It has also been suggested that ehrlichiosis can be transmitted from mother to child, and through direct contact with slaughtered deer. (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.
