Which term describes a spiral-shaped bacterium?

Which term describes a spiral-shaped bacterium?

• A. Virus
• B. T Lymphocyte
• C. Spirillum
• D. Protozoan

Answer: (C)

Bacteria come in several shapes, and a spiral-shaped bacterium is described by the term Spirillum. Spirilla are a type of bacteria with a helical, winding form, often with external flagella that aid movement. This sets them apart from viruses (which are not cells), T lymphocytes (a type of immune cell), and protozoans (single-celled eukaryotes). So the word that fits a spiral-shaped bacterium is Spirillum.
