title: Types of avian infectious bronchitis strains isolated in Quebec.
abstract: Between 1976 and 1980, 24 isolates of infectious bronchitis virus were obtained from Quebec flocks. The serological classification of these isolates was demonstrated by cross neutralization tests using antisera to 13 different reference virus strains. Of the 24 isolates, ten were identified as Connecticut, six Holland and one SE-17 types. Seven strains did not react with any of the specific antisera.
