Helicobacter Forums

One of the first bugs to be sequenced, H.pylori has a small genome (1.6 MD) befitting its lifestyle in a hostile acidic mucosal niche. Of the 1500 genes, 750-1000 are essential, the others are different in each strain. Hp has an "open pan-Genome" which means the more strains you look at the more genes you will find - i.e. you will never have a complete set of all its possible genes!
