Overview
Historical Perspective
Investigations carried out in the mid 1970's by Tafari et al. described the isolation of Ureaplasma urealyticum from the lungs of stillborn infants with pneumonitis, and it is one of the earliest investigations that suggested the possible pathogenic role of U. urealyticum in neonatal disease.[1] Waites et al. reported the first case of suspected neonatal ureaplasmal pneumonia with sepsis and persistent pulmonary hypertension of the newborn in the 1980's.[2] Several case reports are now available in the literature documenting the isolation of Ureaplasma urealyticum and Ureaplasma parvum in fetal lung tissue, cord blood, pulmonary secretions, pleural fluid, lung tissue, and blood stream of neonates with pneumonia.[1]
Pathophysiology
Pathogenesis
The role of Ureaplasma infection in preterm delivery
- Ureaplasma species are considered to be of low virulence, and 40-80% of healthy women have Ureaplasma species (commonly U. urealyticum and U. parvum) in their genital tract.[3][4][1][5]
- Controversial evidence exists supporting the association between genital colonization with Ureaplasma species and complications of pregnancy such as preterm delivery.[6]
