Pus is an exudate, typically white-yellow, yellow, or yellow-brown, formed at the site of inflammation during infection.^[1] 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 or pimple.

Pus consists of a thin, protein-rich fluid, known as liquor puris, and dead leukocytes from the body's immune response (mostly neutrophils). During infection, macrophages release cytokines which trigger neutrophils to seek the site of infection by chemotaxis. There, the neutrophils engulf and destroy the bacteria and the bacteria resist the immune response by releasing toxins called leukocidins.^[2] As the neutrophils die off from toxins and old age, they are destroyed by macrophages, forming the viscous pus.

Bacteria that cause pus are called suppurative, pyogenic,^[2]^[3] or purulent. If the agent also creates mucus, it is called mucopurulent. Purulent infections can be treated with an antiseptic.

Despite normally being of a whitish-yellow hue, changes in the color of pus can be observed under certain circumstances. Pus is sometimes green because of the presence of myeloperoxidase, an intensely green antibacterial protein produced by some types of white blood cells. Green, foul-smelling pus is found in certain infections of Pseudomonas aeruginosa. The greenish color is a result of the pyocyanin bacterial pigment it produces. Amoebic abscesses of the liver produce brownish pus, which is described as looking like "anchovy paste". Pus can also have a foul odor.^{[medical citation needed]}

In almost all cases when there is a collection of pus in the body, the clinician will try to create an opening for it to evacuate - this principle has been distilled into the famous Latin aphorism "Ubi pus, ibi evacua"

Some common disease processes caused by pyogenic infections are impetigo, osteomyelitis, septic arthritis, and necrotizing fasciitis.^[4]^{[not in citation given]}

Pyogenic bacteria[edit]

A great many species of bacteria may be pyogenic. The most commonly found include:^[5]^{[unreliable medical source?]}

Staphylococcus aureus
Staphylococcus epidermidis
Streptococcus pyogenes
Escherichia coli (Bacillus coli communis)
Streptococcus pneumoniae (Fraenkel's pneumococcus)
Klebsiella pneumoniae (Friedländer's bacillus)
Salmonella typhi (Bacillus typhosus)
Pseudomonas aeruginosa
Neisseria gonorrhoeae
Actinomyces
Burkholderia mallei (Glanders bacillus)
Mycobacterium tuberculosis (tubercle bacillus)
