Talk:H antigen

Bacteria
As far as I am aware, H antigen also refers to bacteria flagellin. If correct then the article should mention this. I think it is the serovars, e. g. H and O (E. coli O strains... O should refers to LPS, H to flagellin) 2A02:8388:1641:8380:0:0:0:2 (talk) 20:20, 27 November 2019 (UTC)
