WebApr 25, 2024 · Bacterial classification is based primarily on their shape. The three most common bacterial shapes are the round or oval coccus, the rod-shaped bacillus and bacteria with a spiral shape. The tetrad occurs in a subgroup of the cocci where the bacterium divides in two planes to form a square of four bacteria called a tetrad. WebBacilli are rod-shaped bacteria. For example, Escherichia. coli, Bacillus thuringiensis, Clostridium tetani etc. Option B: This bacteria has a spiral shape. Examples include Campylobacter jejuni, Helicobacter pylori, etc. Option D: These are bacteria that have a spherical shape. Examples include Streptococcus, Staphylococcus, etc. Final answer:
