Relapsing fever bacterium (gray) on red blood cells | ZEISS MicroscopyThe long, spiral-shaped bacterium (gray) in this image causes relapsing fever, a disease characterized by recurring high fevers, muscle aches and nausea. The relapses result from the bacterium’s unusual ability to change the molecules on its outer surface, allowing it to dodge the human immune system. The disease is transmitted through the bite of a tick (not the same species that transmits Lyme disease) and is found in parts of the Americas, the Mediterranean, central Asia and Africa.
