Resistance To Antibiotics: When 1+1 Is Not 2- Genetic Interactions Underlie Multi-resistant Bacteria

The evolution of multiple **antibiotic resistances** is a global and difficult problem to eradicate. Isabel Gordo, a group leader at the Instituto Gulbenkian de Ciência (IGC)- Portugal, reports in the paper published in the latest issue of **PLoS Genetics**, that the deleterious effect associated with the acquisition of resistance by a bacteria can be suppressed by the acquisition of a new resistance to another **antibiotic**. These findings have direct implications for the approaches taken to tackle the problem of multi-resistance to antibiotics and in the choice of antibiotics to be administrated to patients.
