Actinomycosis: Let's learn about this rare bacterial infection.

Actinomycosis: Let's learn about this rare bacterial infection.

Did you know that we all have millions of bacteria living harmlessly inside and on our skin? They are also beneficial to us. But sometimes, when these harmless bacteria get into places they shouldn't be, they start causing problems. One such rare, strange bacterial infection is called actinomycosis . It's a slow-growing, but potentially serious infection that can cause serious problems if left untreated. So, let's talk a little more about this, shall we?

What exactly is actinomycosis?

Simply put, actinomycosis is a rare infection caused by a type of bacteria called Actinomyces . This bacteria normally lives harmlessly in our mouths, throats, intestines, and sometimes in the vagina of women. Just like other beneficial bacteria in our bodies.

But, if a surgery, injury, or other illness forces these bacteria to travel outside of their normal range, to a place they shouldn't be, that's when the problem begins. There, these bacteria grow and cause an infection.

This infection causes pus-filled cavities or abscesses . Around them, lump-like tissue also forms. The most unusual thing is that this infection spreads to the surrounding tissues. Often, this causes a tunnel-like wound under the skin. Inside these wounds, you can see small yellow granules called "sulfur granules" along with yellow pus. Despite this name, they do not actually contain sulfur. They get their name from their yellow color. These granules are formed by the accumulation of our immune cells and bacterial fragments.

Another thing is that it can sometimes take weeks, even months, for symptoms to appear after the infection begins.

What are the types of actinomycosis?

Actinomyces bacteria can cause infections in various parts of the body. They are classified based on the site of infection.

  • Cervicofacial actinomycosis: This is the most common type. It can affect your face, mouth, nose, neck, or jaw. It is sometimes called "lumpy jaw," because it causes a lump in the jaw. For example, this condition can occur if the bacteria enters through a tooth extraction or a gum injury.
  • Thoracic or pulmonary actinomycosis: This affects your lungs or chest area. For example, it can occur if food or drink gets stuck in your lungs (aspiration).
  • Uterine or pelvic actinomycosis:This is a type of cancer that affects women. It can affect the pelvic area and reproductive organs, such as the uterus, fallopian tubes, and fallopian tubes. This risk is especially high in women who use an intrauterine device (IUD), especially if the IUD has been in place for a long time.
  • Abdominal actinomycosis: This affects the intestines or other abdominal organs. For example, it can develop as a result of a condition such as appendicitis or after abdominal surgery.

What symptoms occur when this disease develops?

The symptoms of actinomycosis vary depending on the site of infection. In addition to common symptoms, there are also specific symptoms for each type.

  • You may get a fever .
  • You may lose weight .
  • In case of a cervicofacial infection: You may develop lumps or fluid-filled areas on the neck, jaw, face, or inside the mouth. You may experience pain when eating and may experience a stiff jaw.
  • In the case of a lung infection (thoracic infection): chest pain, cough, and sometimes blood when coughing.
  • Abdominal or pelvic infection: Symptoms such as abdominal pain and bloating may occur.
  • Pelvic infection: Women may experience unusual vaginal discharge or bleeding.

Remember, because the Actinomyces bacteria grow so slowly, it can take months, or even years, for symptoms to appear after the surgery or illness that started the infection. That's why it can sometimes take a while to recognize it.

Why does this actinomycosis occur?

The main cause of this is the bacterial species `Actinomyces israelii (A. israelii)` . However, several other `Actinomyces` species, such as `A. naeslundii`, `A. odontolyticus`, `A. viscosus`, `A. gerencseriae`, can also cause this infection.

Normally, these bacteria live in the mucous membranes of our throat, gut, and vagina. As long as they are there, they are not a problem. However, if they get a chance to go somewhere they are not supposed to be, such as deep tissue, they multiply there and start an infection.

How does this get transmitted to us... or developed?

The most important thing is that actinomycosis is not a contagious disease. It cannot be spread from one person to another.

This occurs when Actinomyces bacteria enter a part of the body where they don't normally live. For example:

  • Gum disease or dental treatment: This is the most common cause. When a tooth is extracted or cleaned, if there is a wound in the gum, bacteria can enter through it.
  • Intrauterine devices (IUDs):Women who wear IUDs, especially if they have been in place for a long time, can develop pelvic infections.
  • Aspiration of food, liquid, or a foreign object into the lungs: This can cause lung infections.
  • Abdominal diseases: Conditions such as appendicitis, diverticulitis, or peptic ulcer disease can allow this bacteria to enter the abdominal cavity.
  • Abdominal surgery: This risk also exists after surgeries such as cholecystectomy and colectomy.

Imagine this. A friend of yours, let's say Nimal, went to a doctor because of a problem with his tooth. The doctor decided to extract the tooth. A few days after the tooth was extracted, Nimal developed a small swelling in the area, which gradually grew larger and began to hurt. It was only when he showed it to a doctor that he learned that it was an actinomycosis infection. The bacteria `Actinomyces` that was in his mouth had entered through the wound where the tooth was extracted.

Who is more likely to develop this? (Risk factors)

Anything that can damage the tissues of the mouth, digestive system, or uterus increases the risk of developing actinomycosis.

  • Diseases or conditions that damage tissues.
  • Poor oral hygiene (poor dental hygiene) can contribute to this, including not brushing your teeth properly and having gum disease.
  • Devices that are implanted inside the body (e.g., an IUD), surgery, or medical procedures. In the case of an IUD, the risk increases the longer it is in the body.
  • People with weak immune systems: People with weak immune systems are more likely to develop these diseases because they have difficulty fighting off infections. This includes people with diabetes, people infected with HIV, and people undergoing cancer treatment.
  • Although the exact cause is unknown, it has been found that men are more likely to develop this disease than women .

What complications can occur if left untreated?

If this is not treated properly, or if the course of antibiotics is not completed, the bacterial infection can spread further and cause serious complications. These include:

  • Tissue death (necrosis): Tissue may die in infected areas.
  • Bone infection (osteomyelitis) and bone destruction: The infection can spread to the bones, causing them to melt and be destroyed.
  • Brain abscess: This dangerous condition can occur, especially if nasal infections spread to the brain.
  • Organ failure: Infection can cause the loss of function of vital organs.

Therefore, it is very important to see a doctor as soon as possible if you have symptoms of this disease.

How do doctors recognize this?

A doctor diagnoses actinomycosis by looking at your symptoms and taking a sample of fluid or tissue from the infected area. A pathologist examines this sample under a microscope to see if the bacteria Actinomyces or "sulfur granules" are present.

Because actinomycosis is a rare disease and sometimes shows symptoms similar to other diseases, such as cancer, it can sometimes take a while to diagnose it accurately.

What are the treatments for this?

Actinomycosis is treated with high doses of antibiotics . Usually, antibiotics are given intravenously (IV) for several days or weeks. After that, you will continue to take the antibiotics as pills to take at home. Sometimes, drainage and debridement of the infected area may be necessary.

There are several types of antibiotics that can be used for this:

  • `Penicillin`
  • `Amoxicillin`
  • `Erythromycin`
  • `Tetracycline`
  • ` Doxycycline ( Doxycycline ) ` (Doxycycline)
  • `Minocycline`
  • `Clindamycin`

The doctor will choose the most suitable antibiotic for you.

How long will it take to recover after taking the medicine? What should we expect?

It can take months, even years, for an actinomycosis infection to fully heal. This is a long-term treatment. If you stop taking antibiotics too soon, the infection may come back or spread. Therefore, it is very important to take the medication exactly as your doctor tells you.

You need to see your doctor regularly to make sure the medication is working, and to keep an eye on your symptoms and tell your doctor immediately if they seem to be getting worse.

What are the chances of recovery if you develop this disease?

Actinomycosis is usually treatable. The best chance of a full recovery is:

  • If the infection is detected early and treatment is started.
  • If you take the full course of antibiotics prescribed by the doctor, exactly as prescribed.
  • Unless you have other immune system problems.

Could this be fatal?

Yes, actinomycosis can be fatal. Although most people recover with treatment, if left untreated or stopped early, the infection can spread and become life-threatening. Infections in the nose, in particular, can be dangerous because they can spread to the brain.

How do you avoid actinomycosis?

To avoid cervicofacial actinomycosis (the most common type), you need to take good care of your oral health.

  • Avoid smoking and other tobacco products completely.
  • Brush your teeth with toothpaste containing fluoride at least twice a day.
  • Floss between your teeth every day.
  • Use an antibacterial mouthwash (it's best to ask your dentist about this).
  • See a dentist regularly. That way, if there is any problem with your teeth or gums, you can identify it early.

It's hard to say there's a specific way to avoid other types of actinomycosis, but they're not that common.

How should I take care of myself?

The best thing you can do as a person with actinomycosis is to take all your medications exactly as prescribed and to keep seeing your doctor on time. Remember that stopping antibiotics too soon can cause the infection to come back and cause serious complications.

When should I see a doctor? / When should I go to an emergency room?

If you feel like you have symptoms of actinomycosis, or if you have a sore that doesn't heal or continues to spread, be sure to see a doctor.

Stay in touch with your doctor while you are being treated for actinomycosis. If you have any problems or if you feel your symptoms are getting worse, tell your doctor right away.

When to go to an Emergency Treatment Unit (ETU) :

If you have these severe symptoms, go to a hospital emergency room immediately:

  • Fever over 103 Fahrenheit (40 Celsius).
  • Very severe pain.
  • If it comes like a seizure.
  • If there is confusion or disorientation.

What should I ask my doctor?

When you go to see your doctor, it's helpful to ask these questions:

  • How do you take care of skin wounds?
  • How long will I have to take antibiotics?
  • How exactly should I take this medicine? (time, before or after meals, etc.)
  • When should I come see you again?
  • What new symptoms should I watch out for? Or what are some of the symptoms I have that could be dangerous if they get worse?

Finally, the most important things you need to remember

While some bacteria on our bodies don't harm us, sometimes they can cause problems if they get into places they're not supposed to. Actinomyces bacteria are no exception. The infection they cause, called actinomycosis, can be long-lasting and can damage tissue.

However, if this is recognized early and treated properly, it can be completely cured. Treatment takes some time, so you need to be patient. See your doctor regularly and follow his instructions exactly. Then, the doctor will prescribe the most suitable antibiotic for you and tell you when you can stop taking the medication. There is nothing to worry about, if you do it right, you can cure this!

👩🏽‍⚕️ Additional questions (FAQs)

💬 Is Actinomycosis a fungal disease of the skin?

Despite the word 'Mycosis' in the name, this is not caused by a fungus! This is an extremely rare, chronic infection caused by a type of anaerobic bacteria called Actinomyces, which normally live harmlessly in our mouths (gums), digestive tracts, and vaginas.

💬 How can this harmless bacteria suddenly become dangerous?

These bacteria can only live in places where there is no air (oxygen). Therefore, when we have a tooth decay, a bad tooth is extracted, or surgery is performed, these bacteria penetrate the tissue (under the oxygen-free area) from the wound, ferment there, and start forming large holes (fistulas) that drain pus from the skin surface.

💬 How long do I need to take medicine to cure this disease?

Because these are thick, stone-like cysts (Woody fibrosis), it is very difficult to get the medicine inside. Therefore, taking antibiotics for a week like for a normal cold will not help. The patient must continue to take antibiotics like Penicillin for 6 months to a year! (If necessary, the pus is removed surgically).
