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.

The first incident of human ehrlichiosis (the infection caused by the Ehrlichia bacterium) was reported in Japan in 1954. An event of human ehrlichiosis was not reported in the United States until 1986. SUMMARY Ehrlichia chaffeensis is an obligately intracellular, tick-transmitted bacterium that is maintained in nature in a cycle involving at least one and perhaps several vertebrate reservoir hosts. Ehrlichia chaffeensis is an intracellular rickettsia-like bacterium that preferentially infects monocytes and is sequestered in parasitophorous vacuoles referred to as morulae.

These bacteria cause the disease ehrlichiosis, which is considered zoonotic, because the main reservoirs for the disease are animals. There are three species of Ehrlichia now known to infect humans: Ehrlichia chaffeensis (>90% of cases), E. ewingii (<10% of cases), and a rare, unnamed species currently designated as E. muris-like (EML). The first two species are transmitted by the Lone Star tick (Amblyomma americanum).

Ehrlichia chaffeensisinfects 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.

Ehrlichiosis is an illness caused by bacteria that’s spread by ticks. The bacteria are in the Ehrlichia group of bacteria. The illness causes fever, muscle aches, and other symptoms. It’s an uncommon illness that can affect people of all ages.

E. chaffeensis outer membrane protein entry triggering protein of Ehrlichia (EtpE) is necessary for bacterial entry into human cells. We investigated the role of EtpE in transmission of the bacteria from tick to Ehrlichia chaffeensis (IgG, IgM) - Human Monocytic Ehrlichiosis (HME) is a tick-borne infection caused by Ehrlichia chaffeensis.

E. chaffeensis is an emerging infectious agent that causes severe and potentially fatal disease in immune-compromised and elderly people (37, 38). This organism has a multigene locus spanning 22 tandemly arranged genes that encode immunodominant 28-kDa outer membrane proteins (p28-Omp) (7, 26, 34, 34, 35, 41, 42, 48).

Two forms, human monocytic ehrlichiosis (HME) and human granulocytic ehrlichiosis (HGE), have been described. HME is often referred to as "spotless" or rashless Rocky Mountain spotted fever, and has been reported in various regions of the United States. The causative agent of HME has been identified as Ehrlichia chaffeensis.

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. Ehrlichia chaffeensisinfects 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. 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.
