Genotyping and Axenic Growth of Coxiella burnetii Isolates Found in the United States Environment.

Coxiella burnetii is a gram-negative bacterium that is the etiologic agent of the zoonotic disease Q fever. Common reservoirs of C. burnetii include sheep, goats, and cattle.

Epizootiological investigation of a Q fever outbreak and implications for future control strategies.

Objective: To describe the epizootiological investigation of an outbreak of Q fever (Coxiella burnetii infection).

Design: Epidemiological study.

Animals: 17 goat herds in Washington, Montana, and Oregon.

Early cytokine and antibody responses against Coxiella burnetii in aerosol infection of BALB/c mice.

Coxiella burnetii, a Gram-negative intracellular bacterium, can give rise to Q fever in humans and is transmitted mainly by inhalation of infected aerosols from animal reservoirs. Serology is commonly used to diagnose Q fever, but the early cellular immune response-i.e.

Presence and persistence of Coxiella burnetii in the environments of goat farms associated with a Q fever outbreak.

Q fever is a zoonotic disease caused by inhalation of the bacterium Coxiella burnetii. Ruminant livestock are common reservoirs for C. burnetii, and bacteria present in aerosols derived from the waste of infected animals can infect humans.

Long-Term immune responses to Coxiella burnetii after vaccination.

Q fever is a zoonotic disease caused by infection with the bacterium Coxiella burnetii. Infection with C. burnetii results in humoral and cellular immune responses, both of which are thought to contribute to protection against subsequent infection.

Coxiella burnetii infection of marine mammals in the Pacific Northwest, 1997-2010.

Q fever is a zoonotic disease caused by the bacterium Coxiella burnetii. Humans are commonly exposed via inhalation of aerosolized bacteria derived from the waste products of domesticated sheep and goats, and particularly from products generated during parturition. However, many other species can be infected with C.

Virulence of pathogenic Coxiella burnetii strains after growth in the absence of host cells.

Coxiella burnetii is a gram-negative bacterium that causes the zoonotic disease Q fever. Traditionally considered an obligate intracellular agent, the requirement to be grown in tissue culture cells, embryonated eggs, or animal hosts has made it difficult to isolate strains and perform genetic studies on C. burnetii.

Coxiella burnetii infection of a Steller sea lion (Eumetopias jubatus) found in Washington State.

A pregnant sea lion stranded in the State of Washington was found to have placentitis caused by a unique strain of Coxiella burnetii. This is the first description of coxiellosis in a sea lion and suggests that exposure to sea lions may be a risk factor for contracting Q fever.

Presence of Coxiella burnetii DNA in the environment of the United States, 2006 to 2008.

Coxiella burnetii is an obligate intracellular bacterium that causes the zoonotic disease Q fever. Because C. burnetii is highly infectious, can survive under a variety of environmental conditions, and has been weaponized in the past, it is classified as a select agent and is considered a potential bioweapon.
