Spirillum (genus)

Spirillum is a genus of bacteria characterized by their spiral or helical shape, resembling tiny corkscrews. These bacteria are typically motile, moving through their environment using flagella—tiny, whip-like structures. Spirillum bacteria are often found in aquatic environments, including freshwater and marine habitats, and some species can be involved in nitrogen fixation or may cause diseases in humans and animals. Their distinctive spiral form helps them navigate through liquids, and they play roles in ecological processes. Overall, Spirillum bacteria are important for understanding microbial diversity and environmental interactions.
