the serologic prevalence of q fever (coxiella burnetii) complement-fixing antibodies in the peninsular bighorn sheep of southern california.q fever is a rare illness in the southern california desert. during the past 34 years only 6 patients have been diagnosed with the disease at the eisenhower medical center, a referral center for much of the desert and surrounding mountains. in all but 2 instances, q fever was identified in patients who have been in contact with imported domestic sheep who are brought to the desert to graze and lamb in the fall and winter. the sheep are sent back to idaho, wyoming, and montana in the spring. with ...200616896140
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.

On May 25, the county ...201121993345
coxiella burnetii serology assays in goat abortion storm.many commercial antibody detection enzyme-linked immunosorbent assay (elisa) kits for q fever utilize the nine mile (montana tick) strain of coxiella burnetii as antigen. an elisa kit manufactured in france employs ovine placenta-sourced antigen and has been used in europe. sera from goats experiencing a q fever abortion storm in the united states were used to compare the sensitivity and specificity of these 2 elisa formats and the q fever complement fixation test (cft). latent class estimates o ...201424532695

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
