Coxiella burnetii

Coxiella burnetii is a short (0.3-1.0 µm), pleomorphic rod, possessing a membrane similar to a Gram-negative bacterium stained by the Gimenez method. While previously classified as a Rickettsia, C. burnetii has been placed into the gamma subdivision of the Proteobacteria, characterizing it closer to Legionella and Francisella than to Rickettsia [9] Q fever is a disease caused by the bacteria Coxiella burnetii. This bacteria naturally infects some animals, such as goats, sheep, and cattle. C. burnetii bacteria are found in the birth products (i.e. placenta, amniotic fluid), urine, feces, and milk of infected animals. People can get infected by breathing in dust that has been contaminated by infected animal feces, urine, milk, and birth products

Coxiella burnetii is 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 Coxiella burnetii infection is a notifiable condition in the US and some other countries..

Q Fever: Causes, Symptoms & Diagnosi

Q fever is a zoonosis caused by Coxiella burnetii, an intracellular gram-negative bacterium that is prevalent throughout the world ().Domestic ruminants are considered the main reservoir for Q fever in humans ().However, other animal species, including pet animals, birds, and several species of arthropods, can be infected by C. burnetii and cause human cases of Q fever (2-5) Coxiella burnetii is a strict intracellular microorganism, included in the γ subdivision of the Proteobacteria phylum ().It is found in close association with arthropod and vertebrate hosts, and it causes Q fever in humans and animals. Cattle, goats, and sheep are the primary reservoirs of human infection SUMMARY Coxiella burnetii is the agent of Q fever, or query fever, a zoonosis first described in Australia in 1937. Since this first description, knowledge about this pathogen and its associated infections has increased dramatically. We review here all the progress made over the last 20 years on this topic Coxiella burnetii is a unique bacterial pathogen that replicates to high numbers in a lysosome-like intracellular niche. This study identified host proteins that contribute to the pathogen's capacity to establish this niche and activate the Dot/Icm secretion system required for intracellular replication. Many host proteins were found to contribute to the establishment of C. burnetii.

PATHOGENICITY/TOXICITY: Coxiella burnetii is the causative agent of Q fever Footnote 4. Infections are asymptomatic in as many as 60% of cases Footnote 6 . Manifestations of Q fever can be affected by age, strain, route of transmission, gender, and inoculum size, and vary from country to country Footnote 1 , Footnote 4 , Footnote 5 1 Introduction. Coxiella burnetii is a Gram-negative bacterium. Based on phylogenic analysis of 16S rRNA, it belongs to the γ subdivision of the Proteobacteria and is distantly related to Rickettsiella grylli, Legionella spp. and Wolbachia persica.The genus Coxiella includes only one species, C. burnetii, in which no differences have been observed in the 16S rRNA sequence of several isolates Detection of Coxiella burnetii, the causative agent of Q fever, by real time PCR.
