====== Pus ======


Pus is an exudate, typically white-yellow, yellow, or yellow-brown, formed at the site of inflammation during bacterial or fungal infection.

An accumulation of pus in an enclosed tissue space is known as an [[abscess]], whereas a visible collection of pus within or beneath the [[epidermis]] is known as a pustule, pimple, or spot.
