Pus is a thick fluid containing dead tissue, cells, and bacteria. Your body often produces it when it’s fighting off an infection, especially infections caused by bacteria. Depending on the location and type of infection, pus can be many colors, including white, yellow, green, and brown. While it sometimes has a foul smell, it can also be odorless. Keep reading to learn more about what causes pus and when you should call your doctor. Pus-causing infections can happen when bacteria or fungi enter your body through: • broken skin • inhaled droplets from a cough or sneeze • poor hygiene When the body detects an infection, it sends neutrophils, a type of white blood cell, to destroy the fungi or bacteria. During this process, some of the neutrophils and tissue surrounding the infected area will die. Pus is an accumulation of this dead material. Many types of infection can cause pus. Infections involving the bacteria Staphylococcus aureus or Streptococcus pyogenes are especially prone to pus. Both of these bacteria release toxins that damage tissue, creating pus. Pus generally forms in an abscess. This is a cavity or space created by the breakdown of tissue. Abscesses can form on your skin’s surface or inside your body. However, some parts of your body are exposed to more bacteria. This makes them more vulnerable to infection. These areas include: • The urinary tract. Most Escherichia coli, a type of bacteria that’s found in your colon. You can easily introduce it into your uri...

Carbuncle A carbuncle is a cluster of boils — painful, pus-filled bumps — that form a connected area of infection under the skin. A boil is a painful, pus-filled bump that forms under your skin when bacteria infect and inflame one or more of your hair follicles. A carbuncle is a cluster of boils that form a connected area of infection under the skin. Boils (furuncles) usually start as reddish or purplish, tender bumps. The bumps quickly fill with pus, growing larger and more painful until they rupture and drain. Areas most likely to be affected are the face, back of the neck, armpits, thighs and buttocks. Symptoms Boils Boils can occur anywhere on your skin, but appear mainly on the face, back of the neck, armpits, thighs and buttocks — hair-bearing areas where you're most likely to sweat or experience friction. Signs and symptoms of a boil usually include: • A painful, red bump that starts out small and can enlarge to more than 2 inches (5 centimeters) • Reddish or purplish, swollen skin around the bump • An increase in the size of the bump over a few days as it fills with pus • Development of a yellow-white tip that eventually ruptures and allows the pus to drain out Carbuncles A carbuncle is a cluster of boils that form a connected area of infection. Compared with single boils, carbuncles cause a deeper and more severe infection and are more likely to leave a scar. People who have a carbuncle often feel unwell in general and may experience a fever and chills. When to se...

A skin abscess is a bump within or below the skin’s surface. It is usually full of pus, painful, and may feel thick and swollen. This is typically caused by a bacterial infection. A skin abscess may appear on any part of your body. It is similar to a pimple but typically larger and deeper under the skin. Abscesses most commonly develop on the: • back • face • chest • lower abdomen • buttocks Skin abscesses can also appear in areas of hair growth, such as your underarms or groin. Most skin abscesses are harmless and may go away without treatment. Over-the-counter (OTC) creams such as topical antibiotic creams and at-home care may decrease swelling and aid in healing in minor cases. Sometimes, skin abscesses are more difficult to treat and may require laceration (cutting) or drainage. In other cases, oral antibiotics may be prescribed along with prescription washes in addition to draining. There are cases in which an abscess can lead to serious, potentially life threatening complications if left untreated. A skin abscess is usually the result of a cut or nick in your skin that allows typical bacteria found on your skin, such as You’re at an increased risk for this bacterial infection if you: • have close contact with an individual who has a Staphylococcus (staph) infection, which is why these infections are more common in hospitals • are living with a chronic skin disease, like • are living with • are living with metabolic syndrome • smoke • have a weakened immune system Oth...

Pus is a whitish-yellow, yellow, or brown-yellow protein-rich fluid called liquor puris that accumulates at the site of an infection. It consists of a buildup of dead, white blood cells that form when the body’s immune system responds to the infection. When the buildup is on or near the surface of the skin, it is called a pustule or • Pus is a natural result of the body fighting infection. • Pus can be yellow, green, or brown, and may in some cases have a foul odor. • If pus appears after surgery, contact a doctor immediately. • Smaller buildups of pus can be self-managed at home. • Larger or less accessible buildups of pus may require surgical intervention and the application of a drainage channel. Share on Pinterest Pus consists of macrophages and neutrophils, sent by the body’s immune system to combat infection. Pus is the result of the body’s natural immune system Leukocytes, or white blood cells, are produced in the marrow of bones. They attack the organisms that cause infection. Neutrophils, a type of leukocyte, have the specific task of attacking harmful fungi or bacteria. For this reason, pus also contains dead bacteria. Macrophages, another type of leukocyte, detect the foreign bodies and Cytokines alert the neutrophils, and these neutrophils filter from the bloodstream into the affected area. The rapid accumulation of neutrophils eventually leads to the presence of pus. Pus is a sign of infection. Pus after surgery indicates that there is a post-surgical complica...

You had a fall and suffered the tell-tale scrape on your knee. Within a week, it’s filled in with green pus. Don’t worry, there’s no alien at play here. Pus is a sign that your body’s defense system has kicked in. All you need to do is figure out what caused the infection your immune system is trying to fight—and learn how to treat it. First, let’s learn a bit more about what pus is. Yes, it’s gross. Yes, it can be smelly. And yes, it’s a sign of infection. But what is it made of? And what is a pus infection? What Is Pus? Pus is a thick, opaque, often whitish-yellow or brownish-yellow fluid that’s formed during an inflammatory response (i.e., in reaction to an infection). It’s made up of dead white blood cells (a.k.a. macrophages and neutrophils), In other words, pus is a natural byproduct of your body’s healing process. It’s akin to an error message on your computer, alerting you to the fact that there’s a bug in your system. Remember your old friend, the pimple? Pus can appear anywhere—on your tonsils, face, inside a joint, on the brain, or in the gastrointestinal tract, for instance. WHAT CAUSES PUS? According to Rebecca Baxt, MD, pus is caused by “collections of white cell...
