Helicobacter pylori (H. pylori) colonize the human stomach and present genetic mechanisms to evade the host immune response allowing their persistence in this habitat for years. A study involving 130 H. pylori strains isolated from patients living in different Chilean cities revealed that, nearly half of them carry the hopE and hopV genes. The results suggest that these genes can be turned on and off, and are likely to be involved in avoiding immune recognition.
