Mycoplasmosis, also known as a Mikoplazmos infection, is a bacterial infection caused by the smallest free-living organisms known as mycoplasmas. These bacteria differ from most others because they lack a cell wall, making them more resistant to antibiotics that target cell wall synthesis. Mycoplasmas can infect various parts of the body, leading to respiratory infections, genital infections, and even joint inflammation.
This article will provide a comprehensive guide on how to identify and treat mycoplasmosis, covering the causes, symptoms, diagnosis, and available treatments. Additionally, we will include five essential FAQs to help answer common questions about the condition.

What Is Mycoplasmosis?
Mycoplasmosis refers to an infection caused by bacteria of the Mycoplasma genus. These bacteria can affect humans, animals, and plants. In humans, Mycoplasma pneumoniae is a common strain, often causing respiratory infections. Another strain, Mycoplasma genitalium, can infect the urogenital tract. Unlike other bacteria, mycoplasmas lack a cell wall, which means they can’t be targeted by some traditional antibiotics.
Types of Mycoplasma Infections
Mycoplasma infections can affect multiple body systems, primarily the respiratory and urogenital tracts. The two most common types are:
Respiratory Mycoplasmosis (Mycoplasma pneumoniae): This is the primary cause of atypical pneumonia, commonly known as walking pneumonia. It leads to mild respiratory symptoms that don’t require hospitalization.
Urogenital Mycoplasmosis (Mycoplasma genitalium): This infection is sexually transmitted and can lead to inflammation in the urinary and reproductive tracts.
Symptoms Of Mycoplasmosis
The symptoms of mycoplasmosis vary depending on which strain of mycoplasma has caused the infection and which part of the body is affected. Here’s an overview of the most common symptoms for both respiratory and urogenital infections:
Respiratory Mycoplasmosis
The most common mycoplasma infection is Mycoplasma pneumoniae, which primarily affects the respiratory system. Symptoms include:
- Persistent dry cough
- Sore throat
- Mild fever
- Fatigue
- Headaches
- Shortness of breath
These symptoms often mimic those of viral respiratory infections, making diagnosis difficult.
Urogenital Mycoplasmosis
The Mycoplasma genitalium strain causes sexually transmitted infections (STIs) and leads to urogenital symptoms in men and women, including:
- Pain or burning during urination
- Genital discharge
- Pelvic pain (especially in women)
- Vaginal bleeding after sex
- Urethral irritation
In men, mycoplasmosis can also lead to epididymitis, causing pain and swelling in the testicles.
Causes Of Mycoplasmosis
Mycoplasmosis is caused by various strains of Mycoplasma bacteria, and the exact cause of the infection depends on the type of bacteria involved. Transmission typically occurs through:
Respiratory Infections
Mycoplasma pneumoniae is spread through respiratory droplets when an infected person coughs or sneezes. It’s highly contagious in closed environments, such as schools or offices.
Urogenital Infections
Mycoplasma genitalium is spread through sexual contact, including vaginal, anal, and oral sex. The use of condoms reduces but does not eliminate the risk of transmission.
Diagnosis Of Mycoplasmosis
Because mycoplasmosis symptoms are often mild and nonspecific, diagnosing the condition can be challenging. However, accurate diagnosis is critical for effective treatment.
Respiratory Mycoplasmosis Diagnosis
Doctors may use the following methods to diagnose Mycoplasma pneumoniae:
- Physical Examination: Listening to lung sounds with a stethoscope for signs of respiratory distress.
- Chest X-rays: These can reveal patterns in the lungs typical of pneumonia, but are not specific for mycoplasma.
- PCR Test (Polymerase Chain Reaction): A nasal swab or sputum sample is used to detect the presence of mycoplasma DNA.
- Serology: Blood tests can check for antibodies to Mycoplasma pneumoniae, indicating a current or recent infection.
Urogenital Mycoplasmosis Diagnosis
For Mycoplasma genitalium, the diagnostic methods include:
- Nucleic Acid Amplification Test (NAAT): A urine sample or swab from the genital area is tested to detect the DNA of Mycoplasma genitalium.
- Urethral or Cervical Swabs: In men, a urethral swab is commonly used, while in women, a swab from the cervix can be used to diagnose the infection.
Treatment Of Mycoplasmosis
The treatment of mycoplasmosis depends on the type and severity of the infection. Since mycoplasma bacteria lack a cell wall, traditional antibiotics like penicillin and cephalosporins are ineffective. Doctors usually recommend macrolides, tetracyclines, or fluoroquinolones.
Respiratory Mycoplasmosis Treatment
For mild respiratory infections, such as walking pneumonia, antibiotics like azithromycin or doxycycline are typically prescribed. In cases where patients don’t respond to these antibiotics, fluoroquinolones like levofloxacin may be used.
Urogenital Mycoplasmosis Treatment
Mycoplasma genitalium infections are treated using azithromycin or moxifloxacin. However, some strains of Mycoplasma genitalium are resistant to azithromycin, requiring the use of second-line antibiotics. Because the infection can be transmitted sexually, it’s important that both partners are treated simultaneously to prevent reinfection.
Preventing Antibiotic Resistance
Antibiotic resistance is a growing concern with mycoplasmosis. To reduce the risk, it’s crucial to:
- Take prescribed antibiotics exactly as directed.
- Complete the full course of treatment.
- Avoid using antibiotics unnecessarily.
Complications Of Untreated Mycoplasmosis
Left untreated, mycoplasmosis can lead to several complications. These complications are typically more severe in individuals with weakened immune systems or chronic health conditions.
Respiratory Complications
- Severe pneumonia: If Mycoplasma pneumoniae progresses, it can lead to more serious pneumonia, which may require hospitalization.
- Bronchitis: Ongoing infection can lead to chronic bronchitis, characterized by long-term inflammation of the bronchi.
- Asthma exacerbation: Mycoplasma infections can worsen asthma symptoms in individuals with pre-existing asthma.
Urogenital Complications
- Pelvic Inflammatory Disease (PID): In women, untreated Mycoplasma genitalium can spread to the uterus and fallopian tubes, causing PID and potentially leading to infertility.
- Epididymitis: In men, the infection can spread to the epididymis, resulting in pain and swelling in the testicles.
Prevention Of Mycoplasmosis
Preventing mycoplasmosis involves reducing exposure to the bacteria that cause it. Some steps to take include:
Preventing Respiratory Infections
- Practice good hygiene: Wash your hands regularly and cover your mouth when coughing or sneezing.
- Avoid close contact with infected individuals: Mycoplasma pneumoniae spreads easily in closed environments.
Preventing Urogenital Infections
Safe sex practices: Use condoms and practice monogamy to reduce the risk of sexually transmitted infections.
Get tested: Regular STI testing helps identify infections early, preventing the spread of mycoplasmosis.

FAQs
What is mycoplasmosis?
Mycoplasmosis is an infection caused by bacteria from the Mycoplasma genus. It can affect the respiratory system, causing walking pneumonia, or the urogenital system, leading to sexually transmitted infections. These bacteria are unique in that they lack a cell wall, making them resistant to certain antibiotics.
How is mycoplasmosis diagnosed?
Mycoplasmosis is diagnosed through various tests, including PCR tests, nucleic acid amplification tests (NAAT), and blood tests. These help detect the presence of Mycoplasma bacteria in the body.
What are the common symptoms of mycoplasmosis?
Symptoms vary depending on the type of infection but typically include cough, fever, sore throat for respiratory mycoplasmosis, and pain during urination, genital discharge, and pelvic pain for urogenital mycoplasmosis.
Can mycoplasmosis lead to complications?
Yes, if left untreated, mycoplasmosis can lead to serious complications such as severe pneumonia, pelvic inflammatory disease, and epididymitis, which can result in infertility in some cases.
How is mycoplasmosis treated?
Mycoplasmosis is treated with antibiotics such as azithromycin, doxycycline, or fluoroquinolones. Since mycoplasma bacteria are resistant to antibiotics that target cell walls, these specific antibiotics are chosen based on the strain and location of the infection.
