Abstract
Avian infectious bronchitis virus (IBV) causes economically important disease in chickens, affecting both respiratory and non-respiratory tissues. Like other coronaviruses IBV virions contain three virus-coded protein structures, the spike (S; surface projection, peplomer), nucleocapsid (N) and matrix (M) proteins1. The polypeptides of M and N proteins have been identified. The M protein comprises a polypeptide of mol. wt. 23 000 (23K) which is glycosylated to different extents, the major glycopolypeptide being about 30K2,3,4. A polypeptide of about 50K forms the N protein5. However, although many papers have been published on the composition of IBV, there has been a distinct lack of agreement on the number and mol. wt. of the polypeptides which form the spikes (for references see1,6.
