A 5,000-year-old Yersinia pestis genome (RV 2039) is reconstructed from a hunter-fisher-gatherer (5300β5050 cal BP) buried at RiΕΕukalns, Latvia. RV 2039 is the first in a series of ancient strains that evolved shortly after the split of Y. pestis from its antecessor Y. pseudotuberculosis βΌ7,000 years ago. The genomic and phylogenetic characteristics of RV 2039 … Continue reading A 5,000-year-old hunter-gatherer already plagued by #Yersinia pestis

Influenza viruses grown in eggs for the purposes of vaccine generation often acquire mutations during egg adaptation or possess different glycosylation patterns than viruses circulating among humans. Here, we report that seasonal influenza virus vaccines possess an egg-derived glycan that is an antigenic decoy, with egg-binding MAbs reacting with a sulfated N-acetyllactosamine (LacNAc). Half of … Continue reading An #Egg-Derived Sulfated N-Acetyllactosamine Glycan Is an Antigenic Decoy of Influenza Virus #Vaccines
