Developmental biology of Coxiella burnetii
Trends in Microbiology, 1999The obligate intracellular bacterial agent of human Q fever, Coxiella burnetii, has a remarkable ability to persist in the extracellular environment. It replicates only when phagocytosed and delivered to the phagolysosome, where it resists degradation. Different morphological forms of the bacterium have different resistance properties and appear to be ...

The Coxiella burnetii Parasitophorous Vacuole
2012Coxiella burnetii is a bacterial intracellular parasite of eucaryotic cells that replicates within a membrane-bound compartment, or "parasitophorous vacuole" (PV). With the exception of human macrophages/monocytes, the consensus model of PV trafficking in host cells invokes endolysosomal maturation culminating in lysosome fusion. C.

AbstractQ fever is a zoonotic infectious disease caused by the Coxiella burnetii bacterium. It is an obligate intracellular pathogen with a high infection capacity that proliferates exclusively in an acidified medium, forming a lysosome-like vacuole. It presents a peculiar phenomenon called “antigenic phase variation,” produced by a modification in the

The efficient application and characterization of DNA from pathology, clinical, vector, and animal reservoir samples require molecular assays comparable in sensitivity to current TaqMan, SYBR Green, and nested PCR assays. The feasibility of this approach has already been demonstrated in characterizing Rickettsiain samples from Arizona, California, and ...

In the past two decades, many Coxiella-like bacteria have been found in hard ticks and soft ticks as well as in vertebrate hosts. It is interesting to note that many ticks harbor Coxiella-like bacteria with high prevalence. Coxiella-like bacteria and virulent Coxiella burnetii have high homology to each other; they form a monophyletic clade based on ...

Isolation of coxiella burnetii in Sweden
Scandinavian Journal of Infectious Diseases, 1991Coxiella burnetii was isolated from sheep placentas, which had been collected from farms harbouring humans seropositive to the organism. The isolation of these bacteria is the final evidence that Q fever is a domestic disease in Sweden.

Binary Fission in Coxiella burneti
Nature, 1968RICKETTSIAE multiply by binary fission; this has been clearly shown for R. mooseri, R. tsutsugamushi, R. rickettsii, R. quintana and R. orientalis1–4. The multiplication of Coxiella burneti is, however, more problematical. The virus-like character of these organisms has often been described5–9. It has often been suggested that there is an eclipse phase;

Abstract:Coxiella burnetiiis an obligate intracellular bacterium that causes a worldwide zoonosis, Q fever, and can be misused as a biological warfare agent. Infection in animals (coxiellosis) is mostly persistent. Infection in humans is often asymptomatic, but it can manifest as an acute disease (usually a self‐limited flu‐like illness, pneumonia, or ...

Gene Inactivation in Coxiella burnetii
2014Coxiella burnetii, the agent of human Q fever, is a zoonotic bacterial pathogen with a worldwide distribution. Owing to an historic lack of methods for genetic manipulation, virulence factors deployed by this bacterium for disease pathogenesis are poorly understood. However, the recent advance of host cell-free (axenic) growth of C.
