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.

Ehrlichia chaffeensis TRP75 Interacts with Host Cell Targets Involved in Homeostasis, Cytoskeleton Organization, and Apoptosis Regulation To Promote Infection

mSphere, 2018
Ehrlichia chaffeensis is an obligately intracellular bacterium that exhibits tropism for mononuclear phagocytes. The mechanisms involved in E. chaffeensis infection of the host cell and evasion of host defenses are not fully defined, but a subset of type

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.

Cell signaling in Ehrlichia infection and cancer: Parallels in pathogenesis

Frontiers in Cellular and Infection Microbiology
Ehrlichia chaffeensis (E. chaffeensis) has recently emerged as an intracellular bacterial pathogen with sophisticated survival mechanisms that include repurposing evolutionarily conserved eukaryotic cell signaling pathways for immune evasion.

The Wolbachia Genome of Brugia malayi: Endosymbiont Evolution within a Human Pathogenic Nematode [PDF]

, 2005
Complete genome DNA sequence and analysis is presented for Wolbachia, the obligate alpha-proteobacterial endosymbiont required for fertility and survival of the human filarial parasitic nematode Brugia malayi. Although, quantitatively, the genome is even

Participatory surveillance reveals marsh deer mortality event during an extraordinary flood in Ibera Wetlands, Argentina

Ecosphere, Volume 16, Issue 2, February 2025.
Abstract Mortality events of marsh deer (Blastocerus dichotomus) have been historically described in the southern margins of its geographical range. Few documented cases show how environmental changes and pathogens interact to trigger mortality scenarios and reveal their causes.
