Brucellosis, a zoonotic bacterial infection responsible for half a million human infections yearly outside the U.S., evades the host's immune system by hiding out inside the endoplasmic reticulum of the normally protective white blood cell. Usually transmitted in unpasteurized, contaminated milk, brucellosis causes debilitating, chronic illness if left untreated. Jean Celli of the Paul G. Allen School for Global Animal Health at Washington State University studies brucellosis behavior in the white blood cells of humans and animals, and his research could lead to useful information regarding treatment of other pathogens such as salmonella and tuberculosis.
