Notes from the field: Q fever outbreak associated with goat farms--Washington and Montana, 2011.On April 22, 2011, the Q fever bacterium Coxiella burnetii was detected in a goat placenta collected from a farm in Washington, where 14 of 50 (28%) pregnant does had aborted since January.

seroprevalence of coxiella burnetii in washington state domestic goat herds.a caprine herd seroprevalence of coxiella burnetii infection was determined by passive surveillance of domestic goat herds in washington state. serum samples (n=1794) from 105 herds in 31 counties were analyzed for c. burnetii antibodies using a commercially available q fever antibody enzyme-linked immunosorbent assay (elisa) test kit. the sera were submitted to the washington animal disease diagnostic laboratory for routine serologic screening over an approximate 1-year period from november, 20 ...201324107207
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. the significance of infection from material deposited in the environment versus transmission directly from infected animals is not known. in 2011, an outbreak of q fever cases on farms in washington and montana was associated with infected goats. a study was u ...201323315737
