1918 RBD D225G in Lung Cases in Ukraine and Norway. -- (Recombinomics)
The above description is from a paper analyzing receptor binding domain differences in sequences from the 1918 pandemic. The New York variant had D225G, the same change found in lung tissues from fatal swine H1N1 sequences in Brazil, Ukraine, and Norway. The above result clearly demonstrated a change in receptor specificity for D225G, which was present in A/New York/1/1918 and A/London/1/1919, demonstrating the same change I 1918 that has been described in 2009.
