Almost 40% of all people are carriers of Staphylococcus aureus (Latin Staphylococcus aureus).

This is a conditionally pathogenic bacterium from the genus staphylococcus and can cause many diseases. Starting from acne and ending with meningitis.

What to do in such a situation? To get started, we recommend reading this article. This article details the methods of dealing with parasites. We also recommend contacting a specialist. Read the article >>>

He often becomes the culprit of nosocomial infection and postoperative complications. Normally, the microorganism is not dangerous; suitable conditions are necessary for the development of infection.

Staphylococcus aureus in throat, nose and intestines

The presence of bacteria on the skin and mucous membranes does not pose a threat to human health. Stable immunity inhibits the growth of bacteria and maintains a balance between the natural microflora that each person has.

Compared to other infectious agents, the bacterium has two advantages:

  • Antibiotic resistance. Due to the presence of special enzymes, the bacterium breaks down penicillin. In addition, the bacterium is widespread and the indiscriminate use of antibiotics by people leads to a mutation of the microorganism, thereby increasing the resistance of the pathogen.
  • High resistance to antiseptics and adverse environmental factors. Even under short-term thermal exposure, the bacteria can survive.



In medicine, there are two types of carriage of Staphylococcus aureus:

  • Temporary.
  • Permanent.

With constant carriage of bacteria, the transition from the category of conditionally pathogenic to pathogenic form. In this case, the microorganism, when transmitted from a carrier to a healthy person, causes an infectious disease.

For the development of infection, special conditions are required:

  • Decreased immunity, vitamin deficiency.
  • Taking wrong antibiotics and other medications.
  • Nervous disorders (stress, depression).
  • Various diseases. Staphylococcus aureus becomes a secondary infection.
  • Surgical intervention in violation of the rules of asepsis.

Staphylococcus aureus in a child and infant

In newborns, the infection most often occurs in the form of pharyngitis and enterocolitis (inflammation of the intestinal mucous walls).

Basically, children suffer from the bacteria in the first months of life and up to 1 year, especially if they were born prematurely or with congenital abnormalities.

Symptoms in children

The clinical picture of the disease, the causative agent of which is Staphylococcus aureus, depends on the state of immunity, the location of bacteria and their pathogenicity. With weak immunity, an increase in body temperature and general intoxication of the body are characteristic.

Localization of bacteria in human systems and organs:

  • Upper respiratory tract. A favorite place for localization of the pathogen. Viruses, hypothermia and abuse of nasal drops contribute to the development of pathology.
  • The gastrointestinal tract. Food poisoning occurs and is manifested by nausea, vomiting and diarrhea. Infection mainly occurs when eating food contaminated with the pathogen.
  • Internal organs. Pathology manifests itself in the form of pneumonia and bacterial endocarditis.

Table with the most common diseases when infected with staphylococcus.

Name of the disease Typical symptoms
Pneumonia Fever, general weakness, shortness of breath, anemia, cough with phlegm.
Pharyngitis On day 2 or 3, a dry cough appears, the voice becomes hoarse, and a runny nose appears.
Enterocolitis Nausea, vomiting, gastrointestinal dysfunction.
Ritter's disease or scalded skin syndrome Skin rash and foci of inflammation with clear boundaries.

Most often, staphylococci cause abscesses, dermatitis and boils. The main threat to children is the waste products produced by bacteria, which can cause infectious-toxic shock.

Treatment in children

Before conducting therapy, it is necessary to study the resistance of the pathogen to antibiotics. In some cases, ointments containing mupirocin are used, if it concerns local diseases: Levomekol, Baneocin and methyluracil ointment.

The main medicines used are:

  • Bacteriophage. The drug contains viruses that infect staphylococci.
  • Antibiotics Amoxiclav, Oxacillin, Vancomycin, Lincomycin and others.

They approach treatment with all seriousness, without violating the dosage and timing of admission. Otherwise, you can increase the resistance of bacteria to medicines.

Staphylococcus aureus in adults

Staphylococcal infections are difficult to treat. Usually, adults begin to self-medicate and postpone the visit to the doctor. Thus, they only increase the set in the clinical picture.

Symptoms and treatment in adults

Typical signs of infection depending on the site of infection:

Hyperemia (redness). The flow of arterial blood to the focus of inflammation increases and venous stasis occurs. Thus, the body removes toxins and debris from bacteria

Hyperemia

  • General or local increase in body temperature. It is a bacteriostatic mechanism for dealing with foreign agents.
  • Puffiness. The corpuscles of blood (leukocytes, etc.) seep through the blood vessels into the inflammatory focus to destroy foreign bodies. As a result, edema appears.

Organ dysfunction. As the infection progresses, healthy cells and tissues are damaged. Dystrophy, necrosis and other pathologies disrupt the functioning of the organ

To achieve a therapeutic effect, tests are taken and the sensitivity of staphylococcus to antibiotics is determined.

Tests for Staphylococcus aureus

There are two main methods for diagnosing and identifying the pathogen:

  • Microscopic.
  • Sowing.

For microscopic examination, smears are stained according to Gram. This method is mainly used for preliminary diagnostics.

Staphylococcus aureus: degree of bacterial growth

Normally, staphylococci live in the human body and do not cause any deviations in health. In this connection, there are certain norms for the content of bacteria on the skin or mucous membranes.

4 degrees of bacterial growth:

  1. Weak growth.
  2. Growth up to 10 colonies of the same species.
  3. Growth from 10 to 100 colonies.
  4. More than 100 colonies.

The first 2 degrees are considered the norm. The 3rd degree indicates a decrease in immunity and the beginning of an increase in the number of bacteria. 4th degree shows the presence of pathology.

Staphylococcus aureus in dogs

Many people have these animals in their homes. A person is constantly in contact with them, especially children and can easily become infected. Especially in the autumn-spring period, when the immunity of animals and humans weakens.

In dogs, Staphylococcus aureus disease mainly manifests itself in the form of skin problems or food poisoning.

Externally, the pathology of the dermis resembles ringworm with pustules.

The hairline falls out profusely, and extensive foci of baldness are formed. An urgent need to contact a veterinarian.

Prevention is the most important step in preventing bacterial infection. A balanced diet, the use of vitamin and mineral complexes, physical education can maintain a strong immune system. And this will be the key to preventing all infections.
