A study was made of the diagnostic value of a soluble Rickettsia burneti antigen for diagnosis of fresh cases of Q-fever in man. In examining 32 patients it was established that intracutaneous test with a soluble antigen became positive from the 5th day of the disease. The maximum rise of this reaction was noted in a majority of the patients by the end of the 24 hours, and then it declined. Soluble antigen injected intradermally 0.1 mi provoked not allergization of the organism or formation of complement fixation antibodies.
