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).

Ehrlichia chaffeensis can be isolated from blood samples or cerebrospinal fluid in cell culture to confirm Bacterial Infections of the Central Nervous System. Carol Glaser, Karen C. bloch, in Handbook of Clinical Neurology, Epigenetics and Human Infectious Ehrlichiosis is the general name used to describe diseases caused by the bacteria Ehrlichia chaffeensis, E. ewingii, or E. muris eauclairensis in the United States. These bacteria are spread to people primarily through the bite of infected ticks including the lone star tick ( Amblyomma americanum ) and the blacklegged tick ( Ixodes scapularis ).

Ehrlichia – Wikipedia

Serologic tests for E. chaffeensis(indirect immunofluorescence) were also negative on day 4 and positive (256) on day 35. Detection of Ehrlichiaspecies–specific DNA was performed by using nested PCR as described (7). Starting on the first day of hospitalization, the patient was treated with doxycycline (14 days) and chloramphenicol (8 days).

Ehrlichia chaffeensis , a tick-transmitted rickettsial agent, causes human monocyte/macrophage-tropic ehrlichiosis. In this study, proteomic approaches were used to demonstrate host cell-specific antigenic expression by E. chaffeensis . 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.

2012-02-08 · Dogs are susceptible to infection with multiple Ehrlichia spp., including E. chaffeensis and E. ewingii, which are predominantly transmitted by Amblyomma americanum (lone star tick), and to E. canis, whose primary vector is considered to be Rhipicephalus sanguineus (brown dog tick) [1–4]. 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 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).
