Of six isolates of infectious bronchitis (IB) virus isolated from commercial poultry flocks in Morocco, five (designated D,E,F, H and M) were related serologically to the Massachusetts serotype, while a sixth, (designated G) was found to be different from any previously reported serotype of IB virus. Neutralising antibodies to this virus have been detected in the sera of commercial chicken flocks from a number of regions in Britain. While isolate G, in common with the other 5 isolates, caused respiratory disease typical of IB in 3-week old SPF chicks, it showed a particular predilection for the alimentary tract, and at various times up to 28 days could be isolated from all regions between oesophagus and bursa of Fabricus. Greatest persistence occurred in the anterior regions (oesophagus, proventriculus and duodenum).
