 research reveals new evolutive mechanism of bacteria that expands pathogenic potential in this study the team of professor penades found a new mechanism that activates and transmits genetic material between the pathogenicity islands found in the chromosomes of bacteria and super bacteria to award them greater virulence and resistance this new evolutive mechanism has been identified in the staphylococcus aureus genus which is of critical priority for the who due to its multi resistance to antibiotics and its ability to cause severe infections
