Outer membrane Protein A plays a role in pathogenesis of Acinetobacter nosocomialis.

abstract：:The hemagglutinin (HA) proteins derived from avian influenza viruses bind specifically to the α2-3 sialoglycan (Sia glycan), whereas human-adapted influenza viruses prefer to bind to the α2-6 Sia glycan. A switch of glycan specificity from α2-3 Sia glycan to α2-6 Sia glycan appears to be critical for a virus to become...
