Infection of a traumatic pelvic hematoma with mycoplasma hominis

Fever developed in a previously healthy young man who had sustained extensive pelvic trauma. Mycoplasma hominis was isolated in pure culture from six of seven specimens taken from a retroperitoneal hematoma over a one-week period, and mycoplasmacidal antibodies were present in high titer in the convalescent-phase serum. The fever abated after thorough surgical drainage of the infected hematoma.
