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 ...

Anaplasmataceae closely related to Ehrlichia chaffeensis and Neorickettsia helminthoeca from birds in Central Europe, Hungary. [PDF]

Antonie Van Leeuwenhoek, 2020
Increasing amount of data attest that (in the context of vector-borne infections) birds are not only important as hosts of blood-sucking arthropod vectors, but also as reservoirs of vector-borne pathogens. From 2015 to 2019 cadavers of 100 birds (from 45

Ehrlichia chaffeensis TRP120-mediated ubiquitination and proteasomal degradation of tumor suppressor FBW7 increases oncoprotein stability and promotes infection. [PDF]

PLoS Pathog, 2020
Ehrlichia chaffeensis (E. chaffeensis) exploits evolutionarily conserved Notch and Wnt host cell signaling pathways to downregulate innate immune host defenses and promote infection. The multifunctional E.

<i>Ehrlichia chaffeensis</i> proteomic profiling reveals distinct expression patterns of infectious and replicating forms. [PDF]

Front Cell Infect Microbiol
Ehrlichia chaffeensis is a tick-transmitted rickettsial pathogen responsible for causing human monocytic ehrlichiosis (HME). The pathogen’s developmental cycle includes infectious dense-core cells (DCs) and non-infectious replicating cells (RCs ...

Ehrlichiosis in Brazil Erliquiose no Brasil [PDF]

Revista Brasileira de Parasitologia Veterinária, 2011
Ehrlichiosis is a disease caused by rickettsial organisms belonging to the genus Ehrlichia. In Brazil, molecular and serological studies have evaluated the occurrence of Ehrlichia species in dogs, cats, wild animals and humans.

Ehrlichia chaffeensis infection in the reservoir host (white-tailed deer) and in an incidental host (dog) is impacted by its prior growth in macrophage and tick cell environments. [PDF]

PLoS ONE, 2014
Ehrlichia chaffeensis, transmitted from Amblyomma americanum ticks, causes human monocytic ehrlichiosis. It also infects white-tailed deer, dogs and several other vertebrates. Deer are its reservoir hosts, while humans and dogs are incidental hosts.

Human ehrlichiosis [PDF]

Vojnosanitetski Pregled, 2006
Background. Human ehrlichiosis is a newly recognized disease. It is a tick-borne disease caused by several bacterial species of the genhus Erlichia. These are small gram-negative pleomorphic cocci, that are obligatory intracellular bacteria.

Multiple Ehrlichia chaffeensis Genes Critical for Its Persistent Infection in a Vertebrate Host Are Identified by Random Mutagenesis Coupled with In Vivo Infection Assessment. [PDF]

Infect Immun, 2020
Ehrlichia chaffeensis, a tick-transmitted obligate intracellular rickettsial agent, causes human monocytic ehrlichiosis. In recent reports, we described substantial advances in developing random and targeted gene disruption methods to investigate the ...

Ehrlichia chaffeensis and E. canis hypothetical protein immunoanalysis reveals small secreted immunodominant proteins and conformation-dependent antibody epitopes. [PDF]

NPJ Vaccines, 2020
Immunomolecular characterization of Ehrlichia chaffeensis (E. ch.) and E. canis (E. ca.) has defined protein orthologs, including tandem repeat proteins (TRPs) that have immunodominant linear antibody epitopes.

Serosurvey of <i>Anaplasma phagocytophilum</i>, <i>Babesia microti</i>, and <i>Ehrlichia chaffeensis</i> 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.
