Glycosylation of Homologous Immunodominant Proteins of Ehrlichia chaffeensis and Ehrlichia canis [PDF]

Infection and Immunity, 2000
ABSTRACT The glycoprotein genes of Ehrlichia chaffeensis (1,644 bp) and Ehrlichia canis (2,064 bp) encode proteins of 548 to 688 amino acids with predicted molecular masses of only 61 and 73 kDa but with electrophoretic mobilities of 120 kDa (P120) and 140 kDa (P140), respectively ...

A case of human monocytic ehrlichiosis in Serbia [PDF]

Srpski Arhiv za Celokupno Lekarstvo, 2014
Introduction. Ehrlichiosis is a bacterial zoonosis transmitted by hematophagous arthropods - ticks. In humans, it occurs as monocytic, granulocytic, and ewingii ehrlichiosis.

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.

Mathematical model of Ehrlichia chaffeensis transmission dynamics in dogs

Journal of Biological Dynamics, 2023
Ehrlichia chaffeensis is a tick-borne disease transmitted by ticks to dogs. Few studies have mathematical modelled such tick-borne disease in dogs, and none have developed models that incorporate different ticks' developmental stages (discrete variable) as well as the duration of infection (continuous variable).

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.

Sequence Determinants Spanning −10 Motif and Spacer Region Implicated in Unique Ehrlichia chaffeensis Sigma 32-Dependent Promoter Activity of dnaK Gene

Frontiers in Microbiology, 2019
Ehrlichia chaffeensis is an obligate intracellular tick-borne bacterium that causes human monocytic ehrlichiosis. Studying Ehrlichia gene regulation is challenge, as this and related rickettsiales lack natural plasmids and mutagenesis experiments are of ...

Image_4_Glutathione Synthesis Regulated by CtrA Protects Ehrlichia chaffeensis From Host Cell Oxidative Stress.TIF

, 2022
Ehrlichia chaffeensis, a small Gram-negative obligatory intracellular bacterium, infects human monocytes or macrophages, and causes human monocytic ehrlichiosis, one of the most prevalent, life-threatening emerging zoonoses.

Mutations in Ehrlichia chaffeensis Causing Polar Effects in Gene Expression and Differential Host Specificities. [PDF]

PLoS ONE, 2015
Ehrlichia chaffeensis, a tick-borne rickettsial, is responsible for human monocytic ehrlichiosis. In this study, we assessed E. chaffeensis insertion mutations impacting the transcription of genes near the insertion sites.
