title: Antibodies against human types A and B influenzaviruses in the sera of animals in Spain.
abstract: Sera from several animal species were subjected to serological tests for antibodies against types A and B influenzaviruses of human origin. Of the swine sera, 13% were positive by the haemagglutination-inhibition test for the human A strain and, of those, 68% were also positive by the neuraminidase-inhibition test. None of the sera tested was positive for the B strain.
