[Observation on the antigenic affinity of Leptospira and Brucella in the serological examination of cattle].
36,9% bovine serums which showed a non-specific reaction in examination for brucellosis had titre greater than or equal to 1:400 leptospirosis agglutinins. 15.1% of the serums showed a positive reaction (greater than 1:800), mostly those against L. sejroe and L. grippotyphosa. The cross reactions, found in individual cases within up to 39 days since the first reaction to brucellosis in cattle may signalize early Leptospira infections.
