Coral-killing army recruits human bugs. (Earth Science: from Boston, at the annual meeting of the Geological Society of America).Coral reefs coral reefs, limestone formations produced by living organisms, found in shallow, tropical marine waters. In most reefs, the predominant organisms are stony corals, colonial cnidarians that secrete an exoskeleton of calcium carbonate (limestone). around the globe are plagued by black-band disease. The telltale black or red mat of bacteria that infects and kills corals is the work of a multitude of pathogens (SN: 4/11/98, p. 229). Now, research on reefs off the Caribbean island of Curacao shows that the lethal legions The Lethal Legion is a name used by four fictional supervillain teams in the Marvel Comics universe. They were dedicated to power, profit, and the destruction of the Avengers. enlist some bacteria that come from people.

Fouke's team then used genetic analyses to identify the bacteria living in and around the corals. They found about 50 species associated with black-band disease, including several previously known only in people. How the people-infecting bacteria promote coral disease remains unclear, says Fouke. --B.H. |
