Abstract
- Previously identified strain-specific genes of Helicobacter pylori were analysed for GC content and preference in codon usage. The results indicate that in H. pylori strain specificity is mainly driven by gene uptake. Incoming strains of Helicobacter or other species can occasionally donate genes but the identification of the donor species is hampered by ongoing evolutionary processes and the lack of an adequate number, or indeed a total absence, of gene homologues.
