Mycoplasma genitalium (MG) is a type of bacteria that can cause sexually transmitted infections (STIs) in humans. Despite being a relatively lesser-known STI compared to others like chlamydia and gonorrhea, MG has gained attention due to its potential to cause serious health complications if left untreated. Understanding the causes of Mycoplasma genitalium infections is crucial for prevention and effective management.

The Key Causes Of MG Infections

Sexual Contact:
The primary mode of transmission for Mycoplasma genitalium is through sexual contact, including vaginal, anal, and oral sex. This bacterium can be present in the genital tract, urethra, cervix, anus, and throat of infected individuals. Unprotected sexual activity with an infected partner increases the risk of acquiring MG.
Multiple Sexual Partners: Engaging in sexual activities with multiple partners without using protection such as condoms significantly raises the risk of contracting Mycoplasma genitalium. The more sexual partners a person has, the higher the chances of exposure to various STIs, including MG.
Lack of Awareness and Testing: One of the challenges with Mycoplasma genitalium is that it often goes undiagnosed due to limited awareness and routine testing for this bacterium. Many individuals may not experience noticeable symptoms or may mistake them for other infections, leading to delayed diagnosis and treatment.
Antibiotic Resistance: In recent years, there has been growing concern about antibiotic-resistant strains of Mycoplasma genitalium. Overuse or misuse of antibiotics, including incorrect dosages or incomplete treatment courses, can contribute to the development of resistant strains, making infections more challenging to treat effectively.
Sexual Health Practices: Certain sexual health practices, such as not using condoms consistently and correctly, can increase the risk of Mycoplasma genitalium infections. Lack of barrier protection during sexual intercourse allows for the exchange of bodily fluids containing the bacterium, facilitating transmission.
Co-infections with Other STIs:

Individuals who have other sexually transmitted infections, such as chlamydia or gonorrhea, are at a higher risk of also being infected with Mycoplasma genitalium. Co-infections can complicate diagnosis and treatment, requiring comprehensive testing and management strategies.
Immunocompromised Conditions: People with weakened immune systems, such as those living with HIV/AIDS or undergoing immunosuppressive therapy, may be more susceptible to Mycoplasma genitalium infections. A compromised immune response can make it harder for the body to fight off bacterial infections effectively.
Vertical Transmission: While less common, there is evidence suggesting that Mycoplasma genitalium can be transmitted from an infected mother to her newborn during childbirth. This vertical transmission route highlights the importance of screening and managing STIs during pregnancy to prevent potential health risks to the infant.
Genetic Factors: Although not fully understood, genetic factors may play a role in predisposing some individuals to Mycoplasma genitalium infections. Research is ongoing to explore the genetic susceptibility to various STIs, including MG, and its implications for prevention and treatment.
Behavioral Factors: Certain behaviors, such as engaging in unprotected sex while under the influence of drugs or alcohol, can increase the likelihood of Mycoplasma genitalium transmission. Risky sexual behaviors can compromise decision-making and lead to higher exposure to STIs.

Mycoplasma genitalium infections are primarily caused by sexual contact with infected individuals, particularly in the absence of protective measures like condom use. Other contributing factors include antibiotic resistance, lack of awareness and routine testing, co-infections with other STIs, immunocompromised conditions, vertical transmission, genetic factors, and risky sexual behaviors. Effective prevention and control strategies for MG involve promoting sexual health education, encouraging regular STI testing, practising safe sex practices, and addressing antibiotic resistance through appropriate treatment protocols.

What is Mycoplasma Genitalium (MG), and how does it cause infections?

Mycoplasma Genitalium (MG) is a type of bacteria that can cause sexually transmitted infections (STIs) in humans. It primarily infects the urogenital tract, including the cervix in women and the urethra in both men and women. MG infections are typically transmitted through sexual contact with an infected individual. The bacteria attach to and invade the cells lining the urogenital tract, leading to inflammation and other symptoms.

What are the common risk factors for Mycoplasma Genitalium (MG) infections?

Several factors can increase the risk of acquiring MG infections: Engaging in unprotected sexual intercourse with multiple partners Having a history of other sexually transmitted infections (STIs) Being sexually active at a young age Having a weakened immune system due to medical conditions or medications Using certain types of contraceptives, such as intrauterine devices (IUDs)

Can Mycoplasma Genitalium (MG) infections lead to serious health complications?

While MG infections often cause mild symptoms or remain asymptomatic, they can lead to complications if left untreated. In women, untreated MG infections can result in pelvic inflammatory disease (PID), which can lead to chronic pelvic pain, infertility, and an increased risk of ectopic pregnancy. In men, MG infections can cause urethritis, leading to discomfort, pain during urination, and potential complications if the infection spreads to the reproductive organs.

How is Mycoplasma Genitalium (MG) diagnosed?

Diagnosing MG infections can be challenging because the bacteria are difficult to culture in standard laboratory settings. However, healthcare providers can use molecular testing methods, such as polymerase chain reaction (PCR) tests, to detect MG DNA in samples collected from the urogenital tract. Testing may involve collecting samples from the cervix, urethra, or urine, depending on the individual's symptoms and risk factors.

What are the treatment options for Mycoplasma Genitalium (MG) infections?

MG infections are typically treated with antibiotics. However, due to increasing antibiotic resistance among MG strains, healthcare providers may need to adjust treatment based on antimicrobial susceptibility testing. Commonly prescribed antibiotics for MG include azithromycin, doxycycline, and moxifloxacin. It's crucial to complete the full course of antibiotics as prescribed and to follow up with healthcare providers for retesting to ensure that the infection has been successfully eradicated.
