ETA: S. aureus is one of the organisms commonly responsible for food poisoning. I thought this would be of interest to those interested in the newest details of how it empowers itself in its toxicity (including grabbing metals from you, whether in your gut or in your nose or on animals that you will be eating). The commentary about possible new treatments attacking the proteins needed to generate the compound used for the metal-scavenging by S. aureus, where the beneficient bacteria in our gut would not be affected (by and large), might also be interesting to some.
