A/Hong Kong/213/97 (HK213; H5N1), isolated from a human, binds to both avian- and human-type receptors, due to a haemagglutinin (HA) mutation probably acquired during adaptation to humans. Duck passage of this virus conferred lethality in ducks. Sequence analyses of the duck-passaged virus revealed that its HA gene reverted back to one recognizing only avian-type receptors, and consequently it ...

The 2012/13 influenza season in Canada has been characterised to date by early and moderately severe activity, dominated (90%) by the A(H3N2) subtype. Vaccine effectiveness (VE) was assessed in January 2013 by Canada's sentinel surveillance network using a test-negative case-control design. Interim adjusted-VE against medically attended laboratory-confirmed influenza A(H3N2) infection was 45% (...

Lectins play important role in innate immunity of animals. The affinity of the natural haemagglutinin of the giant freshwater prawn Macrobrachium rosenbergii towards vertebrate erythrocytes and its level with relation to sex, size and moult stages were studied. The strongest agglutinating titres in haemolymph of prawns were marked against guinea pig, chicken, Clarias batrachus, and rabbit eryth...

Virus-like particles with genetically defined envelope proteins were generated from cDNA in order to examine the requirement of Sendai virus haemagglutinin-neuraminidase (HN) protein for particle formation, and the role of fusion protein (F) in receptor binding and membrane fusion. Characterization of particles devoid of HN protein showed that particle formation was unimpaired by the absence of...

During the formation of incomplete fowl plague virus, normal amounts of viral compounds are synthesized. The S-antigen, however, cannot be demonstrated within the cytoplasm in appreciable amounts by fluorescent antibody. The oligonucleotide pattern and the specific radioactivity of the ribonucleic acid (RNA) of incomplete forms are almost identical with those of standard virus. In contrast to c...

The fluorescent antibody technique using both monoclonal and specific polyclonal virus antibodies was applied to investigate the nature of the inclusions seen in the abnormal osteoclasts associated with Paget's bone disease. The results show that antigens of measles virus, simian virus 5 (SV5) and human parainfluenza virus type 3 (PF3) could be detected in the osteoclasts but not in control bon...

The partial sequencing of the internal and the neuraminidase genes of isolate 268/96 obtained from a woman with conjunctivitis showed all seven to have closest homology with avian influenza viruses. The entire nucleotide sequence of the haemagglutinin gene of 268/96 had close, 98.2%, homology with anH7N7 virus isolated from turkeys in Ireland in 1995. This appears to be the first reported case ...

Here we proposed a Chemical Bond based Elastic Network Model (CB-ENM) method, which was demonstrated with a better performance in representing functional movements, especially the local motions, than the conventional normal mode analysis. CB-ENM was applied in characterising functional motions in surface glycoprotein Haemagglutinin (HA) of H5N1 highly pathogenic avian influenza virus. Eleven lo...
