摘要

Billions of bacteria live in our intestines, supplying us with essential vitamins and helping us digest food. Recent research suggests that in some animals, and perhaps in humans as well, such bacterial guests may play an even more fundamental role: they may influence the normal development of some internal organs. Margaret McFall-Ngai, a developmental biologist at the University of Hawaii, studies the partnership between a squid and the luminous bacteria that live inside its light-emitting organ. Unlike our intestines, which have hundreds of species of resident bacteria, the squid's organ shelters only one type of microbe. By examining this relatively simple symbiosis, McFall-Ngai hopes to gain insight into more complicated interactions.
