the norm of staphylococcus in a throat smear

Most throat diseases (tonsillitis, pharyngitis) are caused by bacteria. Very often, the causative agent of throat diseases is Staphylococcus aureus or Staphylococcus Aureus.

The etiological factor for diseases of this type is the bacterium Staphylococcus aureus. This bacterium has a spherical shape and forms clusters in the shape of a bunch of grapes. Staphylococcus aureus is called Staphylococcus aureus due to the pigment that gives the bacterium a golden color, which is clearly visible under a microscope.

Causes of the disease

Staphylococcus aureus belongs to the opportunistic flora of the human body. It lives on various parts without causing disease. However, under certain conditions of decreased immunity, it is activated with the subsequent development of an infectious disease. The main reasons for the activation of the pathogenic properties of Staphylococcus aureus are:

• Hypothermia, both general and local (use of cold foods and drinks),
• decreased immunity due to stress, lack of sleep,
• bad habits in adults - smoking, alcohol abuse,
• the child's usual use of high-calorie sweet foods (sugar is the preferred food of Staphylococcus aureus),
• metabolic diseases and diabetes,
• immunodeficiency - AIDS HIV, congenital deficiency of local immunity.

Duration of treatment and rules that must be followed during therapy

The period of treatment for staphylococcus is individual in each specific case. Some patients recover within a week, but for many, the treatment process is delayed for more than 6 months. First of all, the recovery period directly depends on the functioning of the immune system and the correct selection of drugs for therapy.

During therapy, the patient is advised to avoid eating fried, smoked, spicy and excessively fatty foods. They undermine the protective mechanism and irritate the lining of the larynx, which causes treatment to be delayed. The diet should be supplemented with foods rich in vitamin C.

In addition to fighting bacteria, you need to get rid of potential sources of infection. The main ones are sinusitis and caries. When treating staphylococcus, it is necessary to simultaneously combat concomitant diseases. Often, an increase in the number of representatives of opportunistic flora coincides with the course of respiratory diseases.

During treatment, your doctor will usually prescribe weekly pap smears. This allows us to identify the presence or absence of progress in therapy. Before taking the test, you should not use medications or folk local remedies. This may cause a distortion of the real situation.

Mechanism of throat injuries caused by Staphylococcus aureus

The mucous membrane of the throat contains a colony of Staphylococcus aureus in the throat from the first days of life . With a normal level of immunity, Staphylococcus aureus in a child’s throat does not multiply beyond a certain number of bacterial cells and does not have pathogenic properties.

But with reduced immunity and high blood sugar levels, cell division is activated, the release of toxins from bacteria increases and, as a result, sore throat develops. The result is acute throat disease, purulent tonsillitis, chronic tonsillitis. An important factor in the development of chronic throat diseases may be the improper use of antibiotics, which develops bacterial resistance to them.

Treatment of infection with drugs

The main goal of treatment will be not only to relieve syndromes, but to eliminate the main causative agent of infection in the child’s body. For an integrated approach to treatment, the presence of concomitant diseases should be taken into account.

The following methods can be used to treat the infection:

• Therapy at the local level , which consists of treating wounds, inflammations, and pustules with special solutions. Effectiveness is noted when treating affected areas with a solution of brilliant green.
• Antibacterial therapy . Drugs should be prescribed only after studies have been conducted to determine the sensitivity of a specific group of bacteria to the type of drug.
• Rinsing inflamed areas.
• Taking vitamin preparations.
• Taking medications to boost immunity.

Staphylococcus aureus in a child, the symptoms of which will vary depending on the type of pathogen, can lead to the need for surgical intervention and blood transfusion in particularly advanced, complicated cases.

After determining the resistance of the infectious agent, the doctor determines a drug from a specific group of drugs (penicillins, cephalosporins, macrolides):

Local medications are prescribed for the treatment of skin inflammation and in case of infection in the nasal mucosa. These products are produced on the basis of the active substance mupirocin; in particular, the drug Bactroban is available in two forms for external and internal use.

As drugs whose action is aimed at increasing the protective properties of the body, the doctor may recommend immunomodulatory agents: IRS-19, Imudon, Broncho-munal.

The use of antibiotics selected by a doctor should be taken responsibly: the entire course must be completed in full and not interrupted in case of a sharp improvement in the condition and subsidence of symptoms. The infection may be untreated, which will lead to the appearance of symptoms in the future when exposed to factors favorable to the bacteria.

The infection will become resistant to previously used drugs, so during subsequent treatment, more powerful drugs will be prescribed, and their effect on the body will be stronger.

Symptoms of a throat disease

The disease is characterized by an acute onset of fever (up to 39.0 C), severe sore throat , especially when swallowing. When examining the throat, you can see tonsils, bright red in color, and possibly the presence of pustules. The disease is characterized by general symptoms of poisoning - weakness, sweating, joint pain, vomiting, loss of appetite. In this form, the sore throat can be contagious to others because Staphylococcus aureus is excreted from the body in exhaled air.

Direct infection occurs through the respiratory tract of a person already infected, when droplets of saliva or mucus are expelled through a sneeze or cough. Indirect infection: In this case, Staphylococcus aureus comes into contact with us through unwashed hands or when we consume contaminated food.

Chronic tonsillitis.

Depending on the development of the disease, this may be:

• primary chronic tonsillitis and
• secondary chronic tonsillitis as a consequence of an untreated disease and the development of resistance to antibiotics in Staphylococcus aureus.

The symptoms are identical in both forms of chronic tonsillitis caused by Staphylococcus aureus. Typical symptoms are local - sore throat when swallowing, sensation of a lump in the throat, red tonsils without purulent plaque.

Pharyngitis.

A disease characterized by symptoms of chronic intoxication. Local symptoms include sore throat, redness of the back of the throat, with swelling of the mucous membranes. Rarely, purulent plaques are present in the back of the throat.

Combined tonsillopharyngitis

This disease is the result of the spread of bacteria throughout the mouth. At the same time, local symptoms are present - sore throat when swallowing, swollen tonsils, redness on the back of the throat.

Symptoms

Staphylococcus aureus is a very pathogenic microorganism. Once in a child's body, they can cause multiple lesions. The severity of adverse symptoms may vary and depend on many factors. Staphylococcal infection in newborns and infants is quite severe.

One of the favorite localizations for Staphylococcus aureus is the mucous membranes of the upper respiratory tract. In this case, infection occurs through airborne droplets.

You can become infected from any sick person or carrier of infection who has microorganisms in the nasal cavity and oropharynx. Even a simple conversation with him can lead to infection. Staphylococcus aureus has a whole arsenal of various toxic substances that lead to severe inflammation. A pronounced inflammatory process leads to the appearance of unfavorable symptoms in the sick child. These symptoms appear taking into account the predominant localization of the inflammatory process.

The severe course of the disease is usually accompanied by severe intoxication syndrome. It is manifested by an increase in body temperature. In severe cases of the disease, it rises to 38-39 degrees. A sick child sleeps poorly and often wakes up at night. Children's appetite decreases. They become more moody and lethargic.

Laboratory diagnostics

Since a disease in the throat can be caused not only by Staphylococcus aureus, but also by other microorganisms (hemolytic streptococcus, adenovirus), diagnosis is carried out through bacteriological smears taken from the tonsils and the back wall of the pharynx. This material, grafted onto a nutrient medium, is examined using biochemical, serological and microscopic methods. In case of disease caused by Staphylococcus aureus, tests are performed to determine its sensitivity to various antibiotics for rational treatment.

Diagnosis of the disease

You will not be able to detect a staphylococcal infection on your own. To do this, you need to go to the doctor, he will take a smear for analysis and only after that competent treatment will be prescribed.

Diagnosis of staphylococcal throat infection

To detect a microorganism, the material under study is inoculated on special nutrient media, ideal conditions for growth and reproduction are created, and placed in an incubator. When staphylococcus colonies grow, a test for resistance to antibacterial drugs is performed.

The forms of the disease can be different: tonsillitis, pharyngitis, laryngitis. The doctor diagnoses which form is present in a sick person based on certain manifestations.

Staphylococcal tonsillitis:

• The palatine arches and tonsils turn red, and there is a layer of yellow-white pus on them, which is easily removed with a spatula.
• A sore throat is felt in the ears, sometimes in the neck; when swallowing, the intensity of the pain increases, which discourages the desire to eat.
• The temperature is rising.
• The lymph nodes of the neck are inflamed and enlarged.

Staphylococcal pharyngitis:

• The back wall of the pharynx is swollen and red, with accumulations of pus visible on it.
• Irritation in the throat, barking cough, the voice becomes hoarse.
• The pain increases when swallowing saliva.
• The temperature rises, the patient shudders and becomes weak.

Staphylococcal laryngitis:

• Painful sensations in the chest.
• The throat feels sore and periodically dries out, which leads to hoarseness and loss of voice in the future.
• Unproductive dry cough, turning into wet cough with green-yellow sputum.
• Prolonged increase in temperature up to 38.0°C.

Treatment of throat infections caused by Staphylococcus aureus

The main therapeutic approach is comprehensive, aimed at destroying the pathogen on the mucous membrane of the throat and eliminating factors that contribute to the transition of Staphylococcus aureus to a pathogenic form. For this purpose the following is used:

• causal treatment,
• pathogenetic therapy,
• immunotherapy,
• Treatment aimed at completely destroying Staphylococcus aureus in the throat is achieved by using antibiotics.
• Recommended antibiotics to combat Staphylococcus aureus;
• a group of penicillin derivatives protected from clavulanic acid (amoxiclav),
• cephalosporins (cephodox, ceftriaxone).

It is important to maintain the duration of treatment until all symptoms disappear. If antibiotic treatment is stopped, the remaining microorganisms may develop resistance to the antibiotics, leading to the disease becoming chronic.

For chronic tonsillitis, development of antibiotic resistance in Staphylococcus aureus. The only method for destroying the pathogen is to use a bacteriophage - a virus that destroys bacterial cells.

Pathogenetic therapy.

Used to relieve intoxication. In case of severe intoxication, detoxification therapy is carried out in the form of intravenous drips with saline solutions.

Immunotherapy.

This is a treatment to strengthen local and general immunity. For this purpose, a group of immunomodulator drugs is used (tincture of Echinacea, Schisandra vulgaris, Eleutherococcus). To strengthen the immune system, you also need a normal diet with adequate intake of vitamins, elimination of stress, and normalization of sleep.

To prevent throat diseases, it is necessary to lead a healthy lifestyle; we must not forget that lack of sleep and stress undermine the human immune system. It weakens and becomes vulnerable to pathogenic flora.

Why staphylococcus is dangerous - a modern view of the problem

This microorganism is “survivable” in the environment; there are 27 strains of varying pathogenicity that can cause more than 100 diseases, so every patient needs to know how to cure staphylococcus in the throat.

Most often, the microorganism settles on the mucous membranes of the throat and nose through airborne droplets or airborne dust, through dirty hands and household items.

The most dangerous is Staphylococcus aureus (S. aureus)

Under certain conditions, Staphylococcus aureus can provoke an infectious and inflammatory process in the nasopharynx - rhinitis, pharyngitis, tonsillitis (catarrhal or purulent), tracheitis and bronchitis.

Particularly dangerous is the presence of bacteria on the mucous membranes of the nasopharynx for a long time or inflammation of the mucous membranes against the background of decreased immunity, so it is important to know how to treat staphylococcus in the nose and throat.

Also, this pathogenic microorganism can enter other organs through the blood or lymph flow:

• brain (meningitis);
• lungs and pleura (pneumonia or pleurisy);
• heart (endocarditis);
• bones and joints (osteomyelitis and purulent arthritis);
• skin (eczema, furunculosis, dermatitis);
• arteries and veins (infectious thrombophlebitis);
• multiple purulent foci in the body (abscesses);
• blood poisoning (sepsis);
• infectious-toxic shock.

This can cause life-threatening diseases, so active treatment of staphylococcus in the nose and throat is necessary immediately after the diagnosis is confirmed.

Staphylococcus aureus in the human body

Depending on the areas of the body colonized by infectious bacteria, outbreaks other than the oral mucosa (tonsils, throat or nose) can occur on the skin, urinary tract, bones, muscles and central nervous system causing various symptoms.

of pustules and serous blisters will appear . If bacteria have settled in the gastrointestinal tract, abdominal pain, diarrhea and vomiting will appear - classic food poisoning.

Staphylococcus aureus often causes cystitis in women who are breastfeeding. In all these cases, there will be an increase in temperature.

Staphylococcus in the throat diagnosis

There are two main methods for diagnosing this disease:

1. Microbiological. A swab is made from the throat or nose, and the resulting material is examined for the presence of staphylococcus. For this purpose, nutrient media are used and the contents of the smear are placed there. After a certain time, the presence of staphylococcus is looked for under a microscope.
2. Serological. A set of 23 bacteriophages is used, which are divided into 4 groups. 1 strain of bacteria kills 1 phage or target group (not currently used because it detects only 60-80% of disease cases).

How to protect yourself and your child from infection?

Children are more susceptible to infection due to their immature immune system. Therefore, it is best to protect yourself and your baby by trying to stay away from the source of infection as much as possible and strengthen your and your baby's immune system. This is true, in general, for any type of infection. Hygiene is very important! You should wash your hands as often as possible because bacteria are found everywhere , especially on everyday items.

As for food, it is necessary to properly cook meat and eggs, cook them in boiling water, for a certain time for each product. You should also wash and disinfect fruits and vegetables before eating them raw. When it comes to intimate hygiene, particularly severe cases of staphylococcal infections are those that can occur in women who use an internal buffer during menstruation, which can become a dangerous carrier of infection.

Staphylococcus aureus infection in the throat

What indicators should be normal?

A bacteriological analysis of the flora in a healthy person will show the presence of beneficial microorganisms that perform protective functions, preventing pathogens from penetrating the mucous membranes of the nasopharynx.

If the analysis is carried out correctly, a small concentration of opportunistic microflora is determined in the throat of a healthy person. Its values ​​should not exceed the result from 103 to 104 CFU/ml.

If the analysis shows an excess of the permissible number of opportunistic microorganisms, this indicates the presence of microflora in the person’s nasopharynx, which is the cause of the development of diseases of the ENT organs.

Staphylococcus

Staphylococcus aureus, the norm of which should not exceed 104 CFU/ml, is an opportunistic microorganism. This means that it is contained in minimal quantities on the nasopharyngeal mucosa and does not provoke the development of any diseases of the ENT system.

Exceeding the norm indicates infection with staphylococcus, which is the cause of the development of the following diseases:

• sore throat and pharyngitis;
• stomatitis, tonsillitis;
• sinusitis;
• gingivitis.

Active growth of staphylococcus is associated with a decrease in the protective functions of the immune system. Children and elderly people are at risk. Treatment is carried out with antibacterial spectrum drugs.

Streptococcus

Streptococcus is an opportunistic microorganism. It is found in minimal quantities on the mucous membranes of the nasopharynx. It is a provocateur of sore throat and scarlet fever. The presence of an increased concentration of pathogenic microflora in the nose can cause the development of bacterial sinusitis.

The development of an infectious process in the nasopharynx is indicated by a streptococcus indicator of 105 CFU/ml. The diagnosis is made by the presence of a specific symptomatic picture in a person.

Candida fungi

Determination of a concentration of Candida fungus in the throat of 105 CFU/ml or more indicates that the patient is infected with candidiasis. The disease develops quickly, has a pronounced and intense symptomatic picture, and can provoke the development of complications in the respiratory system. The norm is the complete absence of fungus in a throat swab or the maximum permissible amount is not higher than 104 CFU/ml.

Neisseria, or Escherichia coli, like pneumococcus, is contained in small quantities in a smear from the nasopharyngeal mucosa.

Pneumococcus is the cause of the following diseases:

• pneumonia;
• bronchitis;
• sepsis of the respiratory system;
• laryngitis, pharyngitis, tracheitis;
• otitis media;
• osteomyelitis.

Excessive concentrations of Neisseria and pneumococcus cause a number of different infectious and inflammatory diseases of the respiratory system.

Depending on the amount of pathogenic microflora in the nasopharyngeal smear, appropriate treatment or preventive measures are prescribed to reduce the concentration of the pathogen and reduce the risk of developing diseases. Therapy consists of the use of antibacterial spectrum drugs.

Interpretation of the results of bacteriological culture indicates the exact amount of pathogenic microflora on the mucous membrane of the nasopharynx. The presence of a pathogenic microorganism may be within normal limits (from 101 to 104 CFU/ml).

The following indicators are alarming and are a sign of the development of infectious and inflammatory diseases of the nasopharynx:

1. 103-104 - the concentration of pathogenic pathogens is within normal limits, the likelihood of developing diseases in the absence of provoking factors is minimal.
2. 105-107 - the content of pathogenic microorganisms is high. The likelihood of developing diseases is maximum. Immediate preventive measures are required to prevent the development of inflammation of the nasopharynx.
3. Drain result - this indicator refers to an extremely high content of pathogenic microorganisms, the number of which cannot be counted.

When a confluent result is obtained, urgent antibacterial therapy is prescribed, aimed at destroying pathogenic microflora. If a person has specific signs indicating inflammatory processes occurring in the nasopharynx, symptomatic therapy is carried out simultaneously with antibacterial treatment.
