Mitochondrial Dysfunction in Ehrlichia canis Infection

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Transmitted by tick vectors, Ehrlichia canis (E. canis) is a Gram‐negative, obligate intracellular bacterium of zoonotic concern that infects both canine and human hosts. Its pathogenesis centers on the targeting of mononuclear phagocytes, where it establishes an intracellular niche by suppressing phagolysosomal fusion and evading immune detection ...

Drug Design and Delivery for Intracellular Bacteria: Emerging Paradigms

Drug Development Research, Volume 86, Issue 8, December 2025.
ABSTRACT Intracellular bacteria exploit host cell niches, such as lysosomes, phagosomes, cytosol, entire cells, and even erythrocytes, to evade immune clearance and escape conventional antibiotics. These environments pose numerous therapeutic challenges, including crossing host cell membranes, navigating endosomal trafficking, tolerating acidic and ...

Ecological dynamics of blacklegged ticks, vertebrate hosts, and associated zoonotic pathogens in northeastern forests

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Specific host‐tick interactions in temperate forest systems influence variation in density and infection prevalence of nymphal blacklegged tick (Ixodes scapularis). The density of infected nymphs (DIN), which is the product of nymphal infection prevalence (NIP) and density of questing nymphs (DON), influences the risk of human exposure to tick‐

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 ...
