Infectious bronchitis virus strain

Abstract

Infectious bronchitis (IB) vaccines for poultry derived from at least one novel virus strain of novel infectious bronchitis serotypes, selected from the group consisting of culture Nos. CNCTC A 07/80, CNCTC A 08/80, CNCTC A 09/80, CNCTC A 010/80, CNCTC A 011/80, CNCTC A 013/80, CNCTC A 014/80, CNCTC A 015/80 and CNCTC A 016/80 deposited at the Czechoslovak National Collection of Type Cultures of the Institute of Hygiene and Epidemiology in Prague, Czechoslovakia and the novel viruses per se, combined virus vaccines and a novel method of protecting poultry from infectious bronchitis.
