Of 1,065 persons sampled during a house-to-house survey of an area of the Department of Curuzú Cuatiá, Province of Corrientes, Argentina, 21 were seropositive to Brucella canis antibodies by the gel-diffusion test, using a saline-extracted B. ovis surface R antigen. Two positive reactors were similarly identified during a survey of rural schools in the Province of Neuquén, which included 887 persons. The findings are discussed in terms of current knowledge of this recently recognized zoonotic infection.
