The recent finding that the E1 glycoproteins of murine coronaviruses contain only O-linked oligosaccharides suggested that this unusual modification might be a distinguishing feature of coronaviruses and might play an essential role in the life cycle of this family of viruses. To examine these possibilities, we analyzed the oligosaccharide moieties of the membrane proteins of the avian coronavi...
a study has been carried out for determining of cross-immunity between massachusetts (mass) m41 and iranian ir/773/2001 (793/b) strains of infectious bronchitis virus. two groups of 20 three weeks old spf chickens vaccinated subcutaneously with two oil-emulsions inactivated infectious bronchitis vaccines (mass m41 and iranian ir/773/2001 strains) that had been manufactured in razi institute in ...
We describe the emergence of a nephropathogenic avian infectious bronchitis virus (IBV) with a novel genotype in India. The Indian IBV isolate exhibited a relatively high degree of sequence divergence with reference strains. The highest homology was observed with strain 6/82 (68%) and the least homology with strain Mex/1765/99 (34.3%).
