Ehrlichia chaffeensis uses its surface protein EtpE to bind GPI-anchored protein DNase X and trigger entry into mammalian cells.

PLoS Pathogens, 2013
Ehrlichia chaffeensis, an obligatory intracellular rickettsial pathogen, enters and replicates in monocytes/macrophages and several non-phagocytic cells. E.

Development of Antisense Tools to Study Bodo saltans and Its Intracellular Symbiont

MicrobiologyOpen, Volume 14, Issue 2, April 2025.
Obligate symbioses present challenges for functional genetic analysis. This study shows that antisense inhibition cannot be used to investigate gene functions in the aquatic symbiosis between Bodo saltans and its bacterial symbiont. Our work stresses the importance of the development of alternative protocols to study the biology of both the ...

Ehrlichia chaffeensis Tandem Repeat Proteins are Related to the RTX Family of Toxins and Secreted by the Type 1 Secretion System

Frontiers in Cellular and Infection Microbiology, 2011
Ehrlichia chaffeensis has type 1 and 4 secretion systems (T1SS and T4SS), but the substrates have not been identified. Potential substrates include secreted tandem repeat protein (TRP) 47, TRP120, and TRP32, and the ankyrin repeat protein, Ank200, that ...

Transmission electron microscopy reveals distinct macrophage- and tick cell-specific morphological stages of Ehrlichia chaffeensis. [PDF]

PLoS ONE, 2012
Ehrlichia chaffeensis is an emerging tick-borne rickettsial pathogen responsible for human monocytic ehrlichiosis. Despite the induction of an active host immune response, the pathogen has evolved to persist in its vertebrate and tick hosts ...

Investigation of the Blood Microbiome in Horses With Fever of Unknown Origin

Veterinary Medicine and Science, Volume 11, Issue 2, March 2025.
ABSTRACT Background Fever of unknown origin (FUO) without a respiratory component is a frequent clinical presentation in horses. Multiple pathogens, both tick‐borne and enteric, can be involved as etiologic agents. An additional potential mechanism is intestinal barrier dysfunction.

Potential mechanisms implied in tick infection by arboviruses and their transmission to vertebrate hosts

Integrative Zoology, Volume 20, Issue 2, Page 315-330, March 2025.
We summarize the recent progress in understanding defense mechanisms in specific tissues or sites that are encountered by arboviruses and discuss their possible roles in virus infection or transmission. Abstract Ticks can transmit many pathogens, including arboviruses, to their vertebrate hosts.

Know Your ABCs: Discovery, Differentiation, and Targeting of T‐Bet+ B Cells

Immunological Reviews, Volume 330, Issue 1, March 2025.
ABSTRACT Since their first description in 2008, T‐bet+ B cells have emerged as a clinically important B cell subset. Now commonly known as ABCs (Age‐associated B Cells), they are uniquely characterized by their expression of the transcription factor T‐bet. Indeed, this singular factor defines this B cell subset.

Ehrlichiosis in a Recent Liver Transplant Recipient Leading to Multiorgan Failure

Case Reports in Transplantation, 2022
Ehrlichia infection has a broad spectrum of diseases ranging from asymptomatic to fatal. While Ehrlichia often presents as a mild form of the disease in immunocompetent patients, immunosuppressed patients are at increased risk for a more virulent and ...

Infections With the Tick-Borne Bacterium "Candidatus Neoehrlichia mikurensis” Mimic Noninfectious Conditions in Patients With B Cell Malignancies or Autoimmune Diseases [PDF]

, 2016
We present a comprehensive study of a new infectious disease in immune compromised patients, neoehrlichiosis. The clinical picture of the disease can be misleading because the symptoms may be misinterpreted to be a worsening of the underlying ...
