Ehrlichia chaffeensis:a Prototypical Emerging Pathogen [PDF]

open access: yesClinical Microbiology Reviews, 2003
SUMMARYEhrlichia 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. The moderate to severe disease caused by E. chaffeensis in humans, first identified in 1986 and reported for more than 1,000 patients through 2000 ...

Surface-Exposed Proteins ofEhrlichia chaffeensis [PDF]

open access: yesInfection and Immunity, 2007
ABSTRACTThe surface proteins ofEhrlichia chaffeensisprovide an important interface for pathogen-host interactions. To investigate the surface proteins ofE. chaffeensis, membrane-impermeable, cleavable Sulfo-NHS-SS-Biotin was used to label intact bacteria.

DETECTION OF ANTIBODIES REACTIVE WITH EHRLICHIA CHAFFEENSIS IN THE RACCOON [PDF]

open access: yesJournal of Wildlife Diseases, 2000
Antibodies reactive with Ehrlichia chaffeensis were detected in raccoon (Procyon lotor) serum samples by using an indirect immunofluorescence assay. Samples from 411 raccoons trapped in the southeastern United States from 1977 to 1999 were tested. Serologically reactive samples with reciprocal titers of > or =16 were detected from 83 raccoons (20 ...

The developmental cycle of Ehrlichia chaffeensis in vertebrate cells [PDF]

open access: yesCellular Microbiology, 2007
Ehrlichia chaffeensis, an obligatory intracellular bacterium, has two forms in mammalian cells: small dense-cored cells (DC) with dense nucleoid and larger reticulate cells (RC) with uniformly dispersed nucleoid. We have determined by electron microscopy that DC but not RC attaches to and enters into the host cells and RC but not DC multiples inside ...

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

open access: yes, 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.

Cost effective, experimentally robust differential-expression analysis for human/mammalian, pathogen and dual-species transcriptomics. [PDF]

open access: yes, 2020
As sequencing read length has increased, researchers have quickly adopted longer reads for their experiments. Here, we examine 14 pathogen or host-pathogen differential gene expression data sets to assess whether using longer reads is warranted.

Experimental infection of dairy calves with Ehrlichia chaffeensis [PDF]

open access: yesJournal of Medical Microbiology, 2007
Human monocytic ehrlichiosis (HME) is a zoonotic emerging tick-borne disease with clinical signs that range from mild symptoms to multiple organ failure and death.Ehrlichia chaffeensis, the aetiologic agent of HME, is reported to infect a divergent range of mammals.

Differentiation of stable kidney function versus progressive dysfunction in dogs

open access: yesJournal of Veterinary Internal Medicine, Volume 37, Issue 6, Page 2241-2250, November/December 2023., 2023
Abstract Background Circulating creatinine and symmetric dimethylarginine (SDMA) are biomarkers of kidney function that have been used variously to define stable vs progressive chronic kidney disease (CKD). Slope monitoring of inverse biomarker values (creatinine−1 or SDMA−1) has shown promise, but quantitative criteria to distinguish stable vs ...

Experimental infection of Rhipicephalus sanguineus with Ehrlichia chaffeensis [PDF]

open access: yesVeterinary Microbiology, 2014
Ehrlichia chaffeensis, the etiologic agent of human monocytic ehrlichiosis, is a tick-borne rickettsial pathogen that is infective to a wide range of mammals, including dogs and people. Amblyomma americanum, the lone star tick, is considered the primary vector of E.
