Bacterial shapes MCQ — 1 Practice Questions with Answers

Explanation

Vibrio is the bacterial form described as comma-shaped or curved rod-shaped, so it matches the given description. Bacilli are rod-shaped bacteria and are not specifically comma-shaped. Cocci are spherical bacteria, commonly seen as single cells, pairs, chains or clusters depending on arrangement. Spirillum refers to spiral or helical bacteria, which have a corkscrew-like form rather than a comma-like curve. The key therefore correctly identifies Vibrio as the comma-shaped bacterial type.
