A bacterial infection on the nail plate typically presents as what color of spot?

A bacterial infection on the nail plate typically presents as a yellow-green spot. This coloration occurs due to the presence of pus, which can result from the infection. When bacteria invade the nail bed or the surrounding tissue, the body's immune response can lead to the buildup of pus, which often has a yellowish or greenish tint. This is commonly observed in conditions like bacterial paronychia, where the skin around the nail becomes infected, leading to discolored areas on the nail itself.

While red spots can occur with irritation or inflammation, and white or black spots may be associated with other conditions or types of trauma, the specific yellow-green coloration is a hallmark of a bacterial infection. Understanding these visual cues is crucial in nail technology, as it helps in identifying infections early on and determining the appropriate course of action for clients.
