Andromeda strain. Any strain of bacteria or other microor- ganism “whose accidental release from a laboratory might have catastrophic effects because of its unknown biochemical make- up” is called an Andromeda strain. The term comes from American author Michael Crichton’s 1971 novel of that title, in which an unknown type of bacteria escapes accidentally from a returning space probe and threatens to contaminate the planet Earth. |
