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

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 ...

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 ...

Coxiella burnetii is a worldwide spread, intracellular and highly infectious, Gram-negative bacterium. The main hosts are the domestic animals, especially cattle, goats and sheep. It is also found in other domestic mammals, birds and ticks. C. burnetii is excreted with lice, urine, feces and the milk of the infected animals.

Recent proteomic studies of C. burnetii, the etiological agent of Q fever, have brought a deeper insight into the pathogen's physiology and offered new possibilities in investigations of inter- or intra-species relatedness. The data generated from these studies in conjunction with the current genomic sequence databases may reveal additional identities ...

Coxiella burnetii Secretion Systems
2012The ability of bacteria to transport proteins across their membranes is integral for interaction with their environment. Distinct families of secretion systems mediate bacterial protein secretion. The human pathogen, Coxiella burnetii encodes components of the Sec-dependent secretion pathway, an export system used for type IV pilus assembly, and a ...

Lipopolysaccharide of Coxiella burnetii
2012A lipopolysaccharide (LPS) is considered to be one of the major determinants of virulence expression and infection of virulent Coxiella burnetii. The LPSs from virulent phase I (LPS I) and from avirulent phase II (LPS II) bacteria were investigated for their chemical composition, structure and biological properties.

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.

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 ...
