Ureaplasma

 [u-re´ah-plaz″mah]
a genus of gram-negative, nonmotile, pleomorphic bacteria that lack a cell wall and form small granular colonies. U. urealy´ticum is a common inhabitant of the genitourinary tract and is associated with sexually transmitted nongonococcal urethritis.

Ureaplasma

(yū-rē'ă-plaz'mă),
A genus of microaerophilic to anaerobic, nonmotile bacteria (family Mycoplasmataceae) with no cell walls. Gram-negative, they are predominantly coccoidal to coccobacillary elements, approximately 0.3 mcm in diameter, which frequently grow in short filaments; colonies are generally small, 20-30 mcm in diameter, and may have no zones of surface growth. Ureaplasma hydrolyze urea with production of ammonia, and are found in the human genitourinary tract, occasionally in the pharynx and rectum. In males, they are associated with nongonococcal urethritis and prostatitis; in females, with genitourinary tract infections and reproductive failure; in neonates, they may cause pneumonia or meningitis. The type species is Ureaplasma urealyticum.
Synonym(s): T-mycoplasma

Development and application of molecular-based methods during the past two decades has significantly improved the ability to detect and identify mycoplasmas and ureaplasmas in clinical specimens, enabled expansion of knowledge about the diseases they may cause, and provided more rapid and accurate diagnosis.
Tanto Ureaplasmas como Mycoplasmas se adhieren al espermatozoide por medio de receptores especificos, que en el caso del Ureaplasma diversum es un sulfoglicolipido, y pueden inducir fragmentacion del DNA ya sea por decondensacion, denaturacion, o por rompimiento de bandas de DNA, lo cual no muestra un dano espermatico inmediato, pero si problemas en el desarrollo y la implantacion embrionaria (25).
