New Light-sensing Ability Discovered In Disease-causing Bacteria

The bacteria that cause **brucellosis** can sense light and use the information to regulate their **virulence**, according to a study in the August 24 issue of the journal Science. The discovery comes after 120 years of research into the disease, which causes abortions in **livestock** and fevers in humans. Researchers found that two other bacteria, including a species that attacks plants, sense light using the same type of protein structure, and at least 94 more species possess the code for it in their **DNA**.
