What type of bacteria, which grows in a spiral, is responsible for diseases like Syphilis, Cholera, and Lyme disease?

The correct answer is Spirilla because this term specifically refers to a genus of bacteria characterized by their spiral shape. Spirilla are known to thrive in various environments and are associated with several significant diseases, including Syphilis, which is caused by Treponema pallidum (a type of spirochete), Cholera from Vibrio cholerae, and Lyme disease caused by Borrelia burgdorferi. The distinct helical or spiral shape of these bacteria is key to identifying them and understanding how they operate in the human body, contributing to the infections associated with them.

In contrast, Staphylococcus refers to a group of bacteria that are typically spherical (cocci) and can lead to various infections but are not spiral in shape. Bacillus denotes rod-shaped bacteria and implies a different structural form entirely. Corynebacterium consists of club-shaped bacteria that can cause diseases like diphtheria, again differing from the spiral structure inherent to Spirilla. Therefore, identifying the type of bacteria based on their shape is crucial in the context of microbiology and the study of infectious diseases.
