Ehrlichia chaffeensis DNA in Haemaphysalis longicornis Ticks, Connecticut, USA [PDF]

Emerg Infect Dis
Informed by passive tick surveillance, we collected questing Haemaphysalis longicornis ticks from southwestern Connecticut, USA. Of 445 ticks tested by PCR, 3 nymphs were positive: 1 for Ehrlichia chaffeensis and 2 for Borrelia burgdorferi.

Serosurvey of Anaplasma phagocytophilum, Babesia microti, and Ehrlichia chaffeensis in Quilombola Communities of Southern Brazil [PDF]

Pathogens
Although quilombola individuals and their dogs may be exposed to hemoparasites such as A. phagocytophilum, B. microti, and E. chaffeensis, no study to date has been conducted in these populations.

Persistent Infection with Ehrlichia chaffeensis

Clinical Infectious Diseases, 1993
Although persistent infection of animals by members of the genus Ehrlichia is well known and may be associated with subsequent severe or fatal illness, persistent infection of humans with Ehrlichia chaffeensis has not been reported. Herein we report a typical case of serologically documented acute ehrlichiosis; despite therapy with tetracycline and ...

Ehrlichia chaffeensis in Missouri ticks.

The American journal of tropical medicine and hygiene, 1998
A nested polymerase chain reaction specific for Ehrlichia chaffeensis was used to attempt to amplify DNA from extracts of 100 individual ticks collected from 13 counties in central Missouri. Seventeen of 59 Amblyomma americanum and six of 41 Dermacentor variabilis ticks exhibited the characteristic 389-basepair product.

Identification of the Antigenic Constituents of Ehrlichia chaffeensis

The American Journal of Tropical Medicine and Hygiene, 1994
Ehrlichia chaffeensis, the novel etiologic agent of human ehrlichiosis in the United States, was first isolated in 1990 and reported in 1991. To analyze the antigenic components of E. chaffeensis, we cultivated these obligate intracellular bacteria in DH82 cells, purified the ehrlichiae by renografin density gradient centrifugation, and examined the ...

Ehrlichia chaffeensis and Rochalimaea antibodies in Kawasaki disease

Journal of Clinical Microbiology, 1993
Sera from 38 patients with Kawasaki disease were tested for immunofluorescent antibodies to Ehrlichia chaffeensis, Rochalimaea henselae, and R. quintana Oklahoma. Only 2.5% of the patients tested positive for E. chaffeensis, and 5% were positive for R. henselae and R. quintana Oklahoma. Our data suggest that Ehrlichia and Rochalimaea spp. do not play a

Fourth Nerve Palsy Caused by Ehrlichia chaffeensis

Journal of Neuro-Ophthalmology, 1997
Two human ehrlichioses occur in the United States: human monocytic ehrlichiosis (HME), which is caused by Ehrlichia chaffeensis that infects mononuclear phagocytes in blood and tissue, and human granulocytic ehrlichiosis (HGE), an infection of granulocytes that is caused by a similar but phylogenetically distinct organism. The clinical features of both
