What is the term for a curved rod in microbiology?

The term for a curved rod in microbiology is vibrio. This terminology is derived from the Latin word "vibriare," which means "to vibrate" or "to oscillate," reflecting the characteristic shape of these bacteria. Vibrio are typically comma-shaped and are a distinct category within the broader classification of bacteria based on their morphology.

Spirillum refers to spiral-shaped bacteria with a helical structure, which is different from curved rods. A rod represents straight cylindrical shapes, typically referred to as bacilli in microbiology, and coccus describes spherical bacteria. Vibrio, therefore, stands out as the correct and specific term for this particular morphology among bacteria.
