#USDA posted an analysis of the D1.1 #H5N1 #birdflu viruses that infected Nevada cows — the new spillover event. They spotted a mutation in the PB2 gene that is associated with mammalian adaptation. What's this mean? Dunno. But 2 spillovers means more could come. www.aphis.usda.gov/sites/defaul...

What are the genotypes promoting human colonization in S. aureus? Authors pooled >~7k genomes from >1500 ppl & looked at genomic variation to infer adaptation. Hits in metabolic genes (esp. nitrogen), QS, and antibiotic targets (incl. new resistance mutations). Cool!
