treponeme
Treponeme is a genus of spirochaete bacteria. These are thin, helical, or spiral-shaped bacteria, typically measuring between 5 and 15 micrometers long and 0.5 micrometers in diameter. They possess flagella-like structures called axial filaments or endoflagella that run within the periplasmic space, allowing them to move in a corkscrew motion through viscous environments.
Several species within the genus Treponema are pathogenic, meaning they can cause disease in humans and animals.
Treponemes are obligate anaerobes or microaerophiles, thriving in oxygen-poor environments. They are difficult to culture in
