Pus is a thick, whitish to yellowish material composed primarily of dead cells that generally forms as a by-product of bacterial infections. The inflammatory cells that participate in the bodyâs immune response at the site of an infection eventually degrade and die, creating the substance known as pus.One of the most common types of bacteria that cause pus formation is Staphylococcus aureus, although any bacterial infection may produce pus.hen pus forms within enclosed spaces in the tissues, it causes abscesses. When it forms on the skin surface, it causes lumps known as pustules or pimples. Pus can also form when infections develop in internal organs, such as the bones, brain, lungs, and gastrointestinal tract.
Actual pus is drainage that is full of dead white blood cells that rush to the site to help the body fight the infection. It also contains dead tissue and bacteria or fungi. Pus is typically white/yellow color, but can be brown or even green. Some types of pus have a foul odor. That said, not all pus is cause for alarm. A pimple, for example, is a normal part of life and is not cause for a trip to the emergency room, but is an example of pus forming at the site of an infection.
