Marchese Morales, Adolfo2016-10-03http://revistas.pucp.edu.pe/index.php/quimica/article/view/15351/15818A group of Chinese scientists have found a new gene in gram negative bacteria, the MCR-1. This gene has given pathogenic bacteria resistance to colistin, which is the antibacterial that medical doctors use as last line of defense against multi-drug resistant infections. Superbacteria with MCR-1 will be potentially epidemic, and diseases that were believed to be controlled such as pneumonia, tuberculosis and urinary tract infections could be lethal again.Un grupo de científicos de China ha encontrado un nuevo gen en las bacterias gram negativas, el MCR-1.
