Abstract: We would like to report some findings regarding the immunological relationship between the New Zealand A and the Australian T strains of infectious bronchitis virus (IBV), using the cross-immunisation test in tracheal organ cultures from immunised birds rather than the conventional cross-neutralisation test. The findings are part of a paper given at the 2nd International Symposium on Infectious Bronchitis at Rauischholzhausen. In an earlier publication, it was reported that the strains of IBV isolated in New Zealand could be grouped into several serotypes, which were distinct from the Australian and many other strains known at that time. The distinction into serotypes may be a convenient method for laboratory work and for epidemiological studies, but it has proved to be too sensitive…
