What are the sites of Colonisation by Staphylococcus aureus?

Approximately 10% of individuals are colonized with S aureus in the perineum and, more uncommonly, in the axillae, pharynx, and hands. Individuals who are permanent carriers serve as reservoirs of the infection for other people.

How many people are colonized with staph aureus?

Up to 30% of the human population are asymptomatically and permanently colonized with nasal Staphylococcus aureus. To successfully colonize human nares, S.

Where does staph colonize?

The nose is the most important site of S. aureus colonization [3], but S. aureus is also found in the pharynx, perineum, axillae and on the skin (predominantly on the hands, chest and abdomen) [4–6].

What does it mean to be colonized by staph?

While 33% of the population is colonized with staph (meaning that bacteria are present, but not causing an infection with staph), approximately 1% is colonized with MRSA. Workers who are in frequent contact with MRSA and staph-infected people and animals are at risk of infection.

Can you get rid of staph colonization?

Treatment of S. aureus colonization/infection in AD is mainly based on antibiotic therapy (topical or systemic). However, overuse of antibiotics can contribute to the development of antibiotic-resistant bacterial strains and the loss of effective antibiotic therapy (Hung et al., 2007).

What is the most common site of colonization by carriers of Staphylococcus aureus?

Colonization among control subjects. aureus isolated at only 1 site, 31 (37%) at 2 sites, and 16 (19%) at all 3 sites sampled (Fig. 1). The throat (68/130, 52%) was the most frequently colonized site, followed by the perianal region (46/130, 35%) and the nose (42/130, 32%).

What percentage of people have staph in their nose?

Staphylococcus aureus (Staf-lo-coc-cus aw-ree-us) is a bacterium that is commonly carried in the nose and on the skin of healthy people. The bacterium is often referred to as “staph.” It is estimated that 30 percent of the population carries staph on the skin or in the nose.

How do I stop being a staph carrier?

Keep your hands clean by washing them thoroughly with soap and water. Or use an alcohol-based hand sanitizer. Keep cuts and scrapes clean and covered with bandages until they heal. Avoid contact with other people’s wounds or bandages.

How long does it take to decolonize staph?

Eradication was assessed at 1 and 4 months. When compared with hygiene education alone (38% eradication), decolonization at 1 month following treatment was significantly more effective with mupirocin (56%, P = . 03) or mupirocin in combination with either diluted bleach baths (63%, P = .

Is MRSA colonization permanent?

Eradication of MRSA carriage is not guaranteed or permanent. Thus, “decolonization” rather than “eradication” may be a more appropriate term. The effect of any eradication or decolonization strategy seems to last 90 days at most, although more prolonged follow-up has been infrequent.

Do all humans have staph?

Many healthy people normally have staph on their skin, in their noses, or other body areas. Most of the time, the germ does not cause an infection or symptoms. This is called being colonized with staph.

Where is staph most commonly found?

Staph bacteria are normally found on the skin or in the nose of about one-third of the population. The bacteria are generally harmless unless they enter the body through a cut or other wound, and even then they usually cause only minor skin problems in healthy people.
