Spirilla

Spirilla are a type of bacteria characterized by their spiral, corkscrew shape. This distinctive form allows them to move efficiently through liquid environments, often using flagella (tiny whip-like structures). Many spirilla are harmless, but some can cause diseases such as syphilis or certain stomach infections. They thrive in moist conditions and are found in water, soil, and sometimes within the bodies of animals. Recognizing their spiral shape helps scientists identify and study them, which is important for understanding their role in ecosystems and their impact on health.
