One thousand and fifty-two sera examined for Q fever yielded 26% of positive results with titres of complement-fixing antibody through 1 in 4 to 1 in 128 and over. On the other hand, 876 sera examined for agglutinating antibody to various leptospirae showed only 0\u00b75% of positive titres of 1 in 80 and over. None of the individuals with positive sera for Q fever had ever been ill with anything resembling Q fever or could remember any ill health in the past; this suggests subclinical infection.
