摘要：The authors report on the results of several years' research into the role of domestic and wild birds in the epidemiology and epizootiology of Q fever in Czechoslovakia. They examined 572 blood specimens taken from domestic birds in an area of endemic Q fever and found positive reactions to the complement-fixation test in hens, turkeys, ducks, geese, and pigeons, with hens showing the highest percentage of positive reactions. In addition, the susceptibility of hens to infection with Rickettsia burnetii was demonstrated experimentally, and excretion of R. burnetii in the stools of hens was demonstrated from the 7th to the 40th day after infection. Complement-fixation tests were also done on 480 blood specimens from wild birds with positive serological reactions in 15.8% of birds living directly on infected farms, 4.3% of birds living in the immediate vicinity of those farms, and 1.8% of birds living independently of human habitations but in an endemic area. R. burnetii was isolated from the spleen and liver of the redstart and the white wagtail and from ectoparasites of swallows.
