Naturally Occurring Ehrlichia chaffeensis Infection in Two Prosimian Primate Species: Ring-tailed Lemurs (Lemur catta) and Ruffed Lemurs (Varecia variegata)

Emerging Infectious Diseases, 2002
A naturally occurring infection of Ehrlichia chaffeensis in lemurs is described. DNA of Ehrlichia chaffeensis was identified by polymerase chain reaction in peripheral blood from six of eight clinically ill lemurs.

Structure of thymidylate kinase fromEhrlichia chaffeensis [PDF]

Acta Crystallographica Section F Structural Biology and Crystallization Communications, 2011
The enzyme thymidylate kinase phosphorylates the substrate thymidine 5'-phosphate (dTMP) to form thymidine 5'-diphosphate (dTDP), which is further phosphorylated to dTTP for incorporation into DNA. Ehrlichia chaffeensis is the etiologic agent of human monocytotropic erlichiosis (HME), a potentially life-threatening tick-borne infection.

Preliminary study of natural reservoirs as sentinels of Anaplasma phagocytophilum and Ehrlichia chaffeensis in Soria, northern Spain [PDF]

, 2013
The serum of foxes and red deer from the Prov- ince of Soria (northern Spain) was screened in indirect immunofluorescence assays to deter- mine whether these animals could be used as sentinels of the tick-borne pathogens Anaplas- ma phagocytophilum and ...

Development of a polyclonal competitive enzyme-linked immunosorbent assay for detection of antibodies to Ehrlichia ruminantium [PDF]

, 2003
A polyclonal competitive enzyme-linked immunosorbent assay (PC-ELISA) is described for detection of antibodies to Ehrlichia (Cowdria) ruminantium by using a soluble extract of endothelial cell culture-derived E.

Lack of Seroreactivity to Ehrlichia chaffeensis Among Rodent Populations [PDF]

Journal of Wildlife Diseases, 1998
A retrospective serosurvey for antibodies to Ehrlichia chaffeensis was conducted on eight species of wild rodents (Mus musculus, Oryzomys palustris, Peromyscus leucopus, Rattus norvegicus, Reithrodontomys humulis, Sciurus carolinensis, Sciurus niger, and Sigmodon hispidus) from the southeastern United States.

Emerging tick-borne infections in mainland China: an increasing public health threat [PDF]

, 2015
Since the beginning of the 1980s, 33 emerging tick-borne agents have been identified in mainland China, including eight species of spotted fever group rickettsiae, seven species in the family Anaplasmataceae, six genospecies in the complex Borrelia ...

Tick-borne ehrlichiosis infection in human beings [PDF]

Journal of Vector Borne Diseases, 2008
Human monocytic ehrlichiosis is a tick-borne infectious disease transmitted by several tick species, especially Amblyomma spp caused by Ehrlichia chaffeensis. E. chaffeensis is an obligatory intracellular, tick-transmitted bacterium that is maintained in

The glycoprotein TRP36 of Ehrlichia sp. UFMG-EV and related cattle pathogen Ehrlichia sp. UFMT-BV evolved from a highly variable clade of E. canis under adaptive diversifying selection [PDF]

, 2017
[Background]: A new species of Ehrlichia, phylogenetically distant from E. ruminantium, was found in 2010 infecting cattle in Canada. In 2012 and 2013, we reported the in vitro propagation, molecular and ultrastructural characterization of Ehrlichia sp ...

Development of a p28-based PCR assay for Ehrlichia chaffeensis [PDF]

Molecular and Cellular Probes, 2004
Detection of Ehrlichia chaffeensis is necessary to study interactions between the parasite and its vertebrate and invertebrate hosts. The purpose of this study was to develop a sensitive, specific PCR assay for E. chaffeensis based on the outer membrane protein gene, p28.
