Abstract excerpt

The antigenic and molecular characteristics of BR-I infectious bronchitis viruses (IBVs) isolated from Brazil are reported. IBVs isolated from commercial flocks with different clinical manifestations between 2003 and 2019 were submitted to antigenic and molecular characterization. The complete S1 glycoprotein gene of 11 field isolates was amplified and sequenced. The virus neutralization (VN) test showed 94.75%...
