Ultrasound-bouncing bubbles help track bacteria in mice

Bacteria engineered with gas vesicles allow researchers to use ultrasound to image the microbes at higher resolutions and greater depths than before
Department: Science & Technology
Keywords: Imaging, ultrasound, bacteria

Some scientists have engineered bacteria to target tumors to deliver cancer drugs or to travel to the gut to fight off pathogenic strains. To improve such possible microbial treatments, researchers would like to know where the engineered microbes actually go in the body. Currently, the most popular method is to get bacteria to express fluorescent proteins and then track the microbes through their bioluminescence. But bioluminescence-based techniques work at depths of only a few millimeters . . .
