Q fever is a zoonosis caused by the intracellular bacterium Coxiella burnetii. Both humoral and cellular immunity are important in the host defence against intracellular bacteria. Little is known about the immune response to C. burnetii infections in domestic ruminants even though these species are the major source of Q fever in humans. To investigate the goat's immune response we inoculated gr...

BACKGROUND Q fever is a neglected zoonosis caused by the bacterium Coxiella burnetii. The knowledge of the epidemiology of Q fever in Kenya is limited with no attention to control and prevention programs. The purpose of this review is to understand the situation of Q fever in human and animal populations in Kenya in the past 60 years, and help identify future research priorities for the country...

Real-time PCR shows the widespread presence of Coxiella burnetii DNA in a broad range of commercially available milk and milk products. MLVA genotyping shows that this is the result of the presence of a predominant C. burnetii genotype in the dairy cattle population.

Coxiella burnetii is responsible for Q fever, a worldwide zoonosis attributed to the inhalation of aerosols contaminated by livestock birth products. Six draft genome sequences of European C. burnetii isolates from ruminants are presented here. The availability of these genomes will help in understanding the potential host specificity and pathogenicity and in identifying pertinent markers for s...

Q fever is a zoonosis caused by Coxiella burnetii. The most frequent clinical expression of the chronic form is a bacterial culture negative aortic or mitral endocarditis. A case of tricuspid valve endocarditis due to C burnetii is described, with a favourable outcome after treatment with doxycycline and hydroxychloroquine.

Following Coxiella burnetii infection, there is a 1 to 5% risk of chronic Q fever. Endocarditis, mycotic aneurysm, and vascular prosthesis infection are common manifestations. We present three patients with endocarditis by C. burnetii concomitant with another bacterial pathogen. Chronic Q fever should therefore be considered in all endocarditis patients in regions where Q fever is endemic.

Q fever is a zoonosis caused by Coxiella burnetii, a unique bacterium that is widespread but infrequently associated with human illness or outbreaks. We report on evidence of infection with C. burnetii in a small group of regular consumers of raw (unpasteurized) milk from the same dairy in Michigan.

The in vitro activity of moxifloxacin against Coxiella burnetii was compared to those of pefloxacin, ofloxacin, and doxycycline. MICs of moxifloxacin ranged from 0.5 to 1 microg/ml for the Nine Mile, Priscilla, and Q212 strains. Moxifloxacin was not bactericidal against C. burnetii at 4 microg/ml.
