Ureaplasma urealyticum as a cause of postpartum fever.

Mycoplasma hominis has been shown to cause a postpartum fever in nonimmune women and among the approximately 5% of febrile postpartum women who have the organism isolated from the blood. Ureaplasma urealyticum causes postpartum fever in the 20% of febrile women with U. urealyticum alone isolated from the endometrium. About 5% of febrile postpartum women have U. urealyticum isolated from the blood. These data suggest that both genital mycoplasmas can cause postpartum fever.
