Summary:
Researchers have discovered a survival mechanism that Salmonella bacteria employ to detect and protect themselves from high levels of iron in the environment. The newly discovered iron sensor provides double-barreled protection since it allows Salmonella to fend off the antibiotic polymyxin, which is produced by a soil microbe. The research offers a hint of the tools that Salmonella calls upon to survive and thrive in hostile environments.
