Q Fever cluster among raw milk drinkers in michigan, 2011.
ABSTRACT 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.

ABSTRACT: Goats are known reservoirs of Coxiella burnetii, the etiologic agent of Q fever. However, there has been very little research on the prevalence of C. burnetii exposure and risk in meat goats farmed in the US. Banked serum samples were secondarily tested for C. burnetii specific antibodies.BMC Research Notes 07/2014; 7(1):421.

ABSTRACT: Background The northern fur seal (Callorhinus ursinus) is an important cultural and nutritional resource for the Aleut community on St. Paul Island Alaska. In recent years, an increasing number of zoonotic pathogens have been identified in the population, but the public health significance of these findings is unknown. To determine the prevalence of Coxiella burnetii and Brucella spp. in northern fur seal tissues, eight tissue types from 50 subsistence-harvested fur seals were tested for bacterial DNA by real-time polymerase chain reaction.FindingsOf the 400 samples tested, only a single splenic sample was positive for Brucella spp. and the cycle threshold (ct) value was extremely high suggesting a low concentration of DNA within the tissue. C. burnetii DNA was not detected.Conclusions Findings suggest that the risk of humans contracting brucellosis or Q fever from the consumption of harvested northern fur seals is low.Acta veterinaria Scandinavica. 10/2014; 56(1):67.
