Question

Which of the groups represent bacterial disease?

Answer 1

Bacteria are microscopic single-celled organisms that are all around us. They come in many different sizes and shapes, and this is a common way to classify them—by their morphology, or shape and appearance. The three basic shapes of bacteria are spherical, rod shaped and spiral. Spiral-shaped bacteria can be further categorized depending in part on how much spiraling they show. Not all bacteria are capable of causing disease, but each morphology-based group has at least some disease-causing representatives.
