In vitro susceptibilities of Coxiella burnetii, Rickettsia rickettsii, and Rickettsia conorii to the fluoroquinolone sparfloxacin [PDF]

Antimicrobial Agents and Chemotherapy, 1991
In vitro susceptibilities of Rickettsia rickettsii, Rickettsia conorii, and Coxiella burnetii to the new fluoroquinolone sparfloxacin (AT-4140; RP 64206) were determined. Plaque and dye uptake assays were used to measure the MICs against R. rickettsii and R. conorii. The susceptibilities of C.

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 ...

In vitro guinea pig leukocyte reactions to Rickettsia rickettsii [PDF]

Infection and Immunity, 1977
The presence of cell-mediated immunity in Rocky Mountain spotted fever-infected guinea pigs was determined by two in vitro assays: whole blood lymphocyte transformation (LT) and macrophage migration inhibition. Increased LT was detected as early as 1 week in guinea pigs infected with Rickettsia rickettsii and treated with oxytetracycline and was ...
