What is Ureaplasma?
Ureaplasma refers to a group of bacteria, commonly found in the urinary or genital tracts of many individuals, that belong to the class Mycoplasma. These organisms are among the smallest known that can replicate independently. Typically, Ureaplasma does not cause symptoms and is considered a commensal infection, meaning it can exist in the body without causing harm. However, under certain conditions, these bacteria can proliferate, leading to infections and other health complications.
Definition and General Characteristics
Discovered in 1954, Ureaplasma is characterized by its tiny size, approximately 15-25 micrometers in diameter, and lacks a cell wall, which is unusual for bacteria. This absence of a cell wall contributes to its resistance to common antibiotics that target cell wall synthesis, like beta-lactams. Ureaplasma produces adenosine triphosphate through the hydrolysis of urea, a process that breaks down urea into ammonia and carbon dioxide. This biochemical activity can be detected in laboratory settings through changes in the pH of culture media, although polymerase chain reaction (PCR) testing is now preferred for its greater sensitivity.
Common Species: Ureaplasma Urealyticum and Ureaplasma Parvum
The two primary species of Ureaplasma are Ureaplasma urealyticum and Ureaplasma parvum. Ureaplasma urealyticum is often associated with sexually transmitted infections (STIs) and conditions like bacterial vaginosis. On the other hand, Ureaplasma parvum is typically less harmful and more likely to be found as a commensal organism. Both species can be transmitted sexually or vertically from mother to offspring and are capable of causing urogenital infections in both men and women. In immunocompromised individuals, such as those with congenital antibody deficiencies or preterm neonates, these bacteria can lead to more severe disseminated infections.
Causes and Transmission
Sexual Transmission
Ureaplasma is primarily transmitted through sexual contact and is prevalent among sexually active adults. It can be transmitted via vaginal, penile, oral, or anal intercourse. Both Ureaplasma urealyticum and Ureaplasma parvum are known to be transmitted in this manner, with Ureaplasma urealyticum more frequently associated with sexually transmitted infections. Even with the use of condoms, transmission is possible, highlighting the need for regular sexual health examinations to limit infection risks.
Mother-to-Child Transmission
The transmission of Ureaplasma from mother to child can occur during pregnancy and childbirth. This bacterium can be passed vertically from the mother to the offspring, potentially leading to complications. It is crucial for pregnant women to receive appropriate screening and treatment for Ureaplasma to reduce the risk of transmitting the infection to the newborn. Studies have shown that newborns can test positive for Ureaplasma when born to infected mothers, emphasizing the importance of maternal health management.
Other Modes of Transmission
While sexual and vertical transmissions are the primary modes, Ureaplasma can also overgrow without any apparent risky behavior, causing irritation and infection. This highlights the bacteria’s ability to become pathogenic under certain conditions, unrelated directly to the mode of transmission. Regular health checks are recommended, especially for individuals planning for pregnancy or those with frequent urogenital symptoms, to manage and prevent Ureaplasma-related complications effectively.
Symptoms and Associated Conditions
Urethritis Symptoms
Urethritis, an inflammation of the urethra, is a common manifestation of Ureaplasma infection, particularly in males. Symptoms typically include a white or cloudy discharge from the penis, difficulty urinating, and a painful or burning sensation during urination. Itchiness or irritation at the tip of the penis is also frequently reported. This condition, often referred to as nonchlamydial nongonococcal urethritis, underscores the need for attention to urinary symptoms that could indicate an underlying Ureaplasma infection.
Bacterial Vaginosis
Bacterial Vaginosis (BV) is another condition frequently associated with Ureaplasma infections, characterized by symptoms such as a fishy odor, vaginal itching, and a greenish discharge. The imbalance in vaginal flora, often with an increase in harmful bacteria like Gardnerella vaginalis, leads to these symptoms. Although BV can occasionally present without symptoms, it is commonly linked with a higher pH level in the vagina, which facilitates the growth of these bacteria. Regular screenings and management of vaginal health are crucial, especially since BV is associated with a greater risk of acquiring other sexually transmitted infections and complications during pregnancy.
Pregnancy Complications
Ureaplasma is significantly associated with various adverse pregnancy outcomes. The bacteria can cause early membrane rupture, leading to preterm birth. Conditions such as chorioamnionitis, an infection of the uterine contents, are also linked to Ureaplasma, particularly when amniotic fluids break prematurely. Furthermore, studies indicate a prevalence of Ureaplasma in the placenta among individuals who experience pregnancy loss. Managing Ureaplasma infections during pregnancy is vital to prevent these complications, including the increased risk of low birth weight and postpartum endometritis.
Diagnosis and Testing
Types of Tests
Testing for Ureaplasma typically involves using a urine sample or a high-vaginal swab, which is then subjected to a PCR test to detect the DNA of the bacteria. This method is highly sensitive and can accurately identify the presence of Ureaplasma urealyticum and Ureaplasma parvum. The PCR test results usually take about 36 hours to process, although samples received over weekends are processed the next working day. For those displaying symptoms, a broader STI screen is recommended, which can identify multiple infections that may present with similar symptoms.
Who Should Get Tested?
Individuals who should consider testing for Ureaplasma include those who have engaged in unprotected oral, anal, or vaginal sex, those with new or multiple sexual partners, and anyone with a current or past partner who has been diagnosed with the infection. Pregnant individuals are also advised to undergo testing due to the potential risks associated with Ureaplasma during pregnancy. While at-home testing kits are available, they require careful sample collection and it is crucial to consult a healthcare professional for confirmatory testing and appropriate treatment if a test returns positive.

Treatment and Prevention
Antibiotics Used
The primary treatment for Ureaplasma infections involves antibiotics, specifically those effective against these bacteria. Macrolide antibiotics such as azithromycin, clarithromycin, and erythromycin are commonly prescribed. Tetracyclines like doxycycline are another option, especially for non-pregnant individuals, as some antibiotics are not safe during pregnancy. In cases where bacteria exhibit resistance, fluoroquinolones like levofloxacin or moxifloxacin may be used as alternatives. Treatment typically includes a course of antibiotics, with the duration and type adjusted based on the individual’s health condition and response to initial treatments.
Preventive Measures
To support the body’s natural defenses against Ureaplasma and other infections, maintaining the pH balance of the genitals is crucial. This can be achieved by washing the external genital area gently with water and avoiding harsh soaps, which can disrupt the natural flora and increase infection risks. Wearing clean, breathable underwear and changing out of sweaty or dirty clothes promptly also helps in preventing overgrowth of harmful bacteria. Regular sexual health examinations and STI testing are recommended, especially for sexually active individuals.
Safe Sex Practices
Practicing safe sex is crucial in preventing Ureaplasma infections and other sexually transmitted diseases. Using barrier methods such as condoms and dental dams during oral, anal, or vaginal sex significantly reduces the risk of transmission. It is important to ensure that any sex toys are cleaned before and after use. Abstinence is the only sure way to prevent Ureaplasma infections, but for sexually active individuals, consistent and correct use of condoms is highly effective in reducing transmission risks.
