Screening of Prophage Sequences Among Helicobacter Pylori

Until recently, Helicobacter pylori was considered a bacterium without prophages. The presence of an incomplete prophage sequence in strain B38 and a complete prophage sequence in strain B45 showed otherwise. Using a PCR strategy, based on degenerated primers designed after aligning bacteriophage integrase genes from H. pylori strains B38 and B45, and H. acinonychis prophage II, we found that integrase sequence...
