What is the Difference Between Ureaplasma Parvum and Ureaplasma Urealyticum?

Ureaplasma parvum and Ureaplasma urealyticum are two species of bacteria that belong to the Ureaplasma genus. They are commonly found in the lower urogenital tract of both men and women and can be transmitted through sexual contact. Here are the main differences between the two:

1. Association with infections: Ureaplasma urealyticum is more likely to be associated with bacterial vaginosis and is considered more of a sexually transmitted infection (STI). In contrast, Ureaplasma parvum is more likely to be a commensal, meaning it can be present in the body without causing any symptoms or infections.
2. Symptoms: Ureaplasma urealyticum has been linked to urogenital tract infections, such as non-gonococcal urethritis in men. On the other hand, Ureaplasma parvum is not thought to be of clinical significance and does not seem to cause infections in men or women.
3. Detection: Both species can be detected using polymerase chain reaction (PCR) tests, which are more sensitive than traditional culture methods. These tests can be performed on urine samples or vaginal swabs.

It is important to note that the clinical role of Ureaplasma parvum and Ureaplasma urealyticum in lower urogenital tract infections in females remains unclear. The British Association for Sexual Health and HIV (BASHH) advises that Ureaplasma is not a major cause for concern and does not require treatment.

Comparative Table: Ureaplasma Parvum vs Ureaplasma Urealyticum

Ureaplasma parvum and Ureaplasma urealyticum are two distinct species of microorganisms that belong to the Ureaplasma genus. Here is a table highlighting the differences between the two:

Both Ureaplasma parvum and Ureaplasma urealyticum are known as commensals in the genital tract and can produce urogenital infections in men and women. They are sexually transmitted bacteria among humans and are associated with various disease states. The distinction between these two species is genome size, 16S rRNA gene sequences, and the presence of different subtypes.
