What type of organism is Ureaplasma urealyticum?

Ureaplasma urealyticum is classified as a bacterium, specifically a member of the class Mollicutes within the phylum Firmicutes. This organism is notable for being one of the smallest free-living bacteria, lacking a cell wall, which distinguishes it from more common bacterial species. Ureaplasma urealyticum plays a role in various human infections, particularly in the urogenital tract.

Understanding its classification is crucial for recognizing its pathogenic potential and the appropriate treatment options. Since it is a bacterium, traditional antibiotics effective against cell wall-containing organisms may not work, prompting the need to understand the unique characteristics of this organism for effective intervention. This bacterium is also of interest in research due to its significant presence in certain populations and its association with specific clinical conditions, emphasizing its relevance in microbiology and healthcare.
