Anticorpos inibidores da hemaglutinação para o vírus parainfluenza 3 (Ha-1), em gado bovino

Abstract

A serological investigation in bovines from 19 Counties in the State of São Paulo, Brazil, evidence that 36.71% of the animals studied had haemagglutination-inhibiting antibodies for myxovirus parainfluenza 3 (HA-1). This result is an indication of dissemination of the infection caused by this virus, although an heterologous strain was used for detecting the above mentioned antibodies.
