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 ...

Natural Infection of Domestic Goats withEhrlichia chaffeensis [PDF]

Journal of Clinical Microbiology, 2000
ABSTRACTThirty-eight domestic goats from an area ofEhrlichia chaffeensisendemicity were tested for antibodies reactive toE. chaffeensisand forE. chaffeensis-specific 16S rRNA gene fragments by an indirect fluorescent antibody test and a nested PCR assay, respectively. Twenty-eight of 38 (73.7%) goats had antibodies reactive toE.

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‐

New insights into molecular Ehrlichia chaffeensis-host interactions [PDF]

Microbes and Infection, 2010
Ehrlichia chaffeensis is an obligately intracellular bacterium that exhibits tropism for mononuclear phagocytes and survives by reprogramming the host cell. Here we review new information regarding the newly characterized effector molecules and the complex network of molecular host-pathogen interactions that the organism exploits enabling it to thrive ...

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 ...
