How salmonella typhimurium colony appear in chocolate agar?

Salmonella typhimurium colonies on chocolate agar typically appear as small, round, and moist with a slightly raised surface. They may exhibit a dull, gray to tan coloration. Unlike some other bacteria, they do not produce a characteristic pigment, so they blend in with the medium, making them less visually distinct. However, the colonies can be further identified through biochemical tests and serotyping.
