Another mutation that is unfortunate for its hosts (but fortunate for people) is the mucA mutation in Pseudomonas aeruginosa, most famous for attacking the lungs of cystic fibrosis patients. The mutation, it seems, makes the bacteria extremely vulnerable to acidified sodium nitrite, a common meat preservative. This doesn't mean that eating bologna is good for CF patients - far from it - but it does promise to deliver some critical treatments for what has usually been considered an untreatable infection. It's been a good week for CF patients.
