UCLA discovery uncovers unique features that advance understanding of the microbe’s movement and infection. African sleeping sickness is a serious infection caused by a parasitic microbe called Trypanosoma brucei. Using an imaging technique called cryo-electron microscopy along with artificial intelligence, a team at the California NanoSystems Institute at UCLA mapped the hairlike flagellum that the microbe uses to propel itself, identifying 154 composite proteins. Findings revealed that the parasite moves in a distinctive style, similar to a dragon boat, with unique adaptations that are essential to its ability to infect its hosts.
