Abstract
The presence of Q fever antibodies in the milk of cattle in Alberta is described. The incidence of positive milk samples rose from 0.8% of herds tested in 1959 to 7.7% in 1964. The largest number of infected animals is in the southern part of the province.
A case of Q fever in an infant is reported. This occurred on the Duffield Indian Reserve near Edmonton in November 1963. Two of 44 blood samples collected at random from asymptomatic individuals on the Reserve in February 1965 contained complement-fixing antibodies to Q fever antigen.
Studies on milk from dairy cattle in the area were negative for Q fever antibodies, and the source of human infection has not yet been determined.
