Which organism is described as having small stick-shaped bodies?

Shape and arrangement seen under staining guide identification of Gram-positive bacilli. Describing organisms as small, stick-shaped bodies points to Corynebacterium, which are short, slender, non-spore-forming rods. They often appear irregular or slightly club-shaped and can show a palisading or “Chinese letters” pattern on smears, which is a characteristic clue for this genus. In contrast, Clostridium and Bacillus are typically larger rods and frequently spore-forming, while Mycobacterium are slender rods that are identified by their acid-fastness rather than a generic “small stick” description. So the description aligns best with Corynebacterium.
