First report of spontaneous intrapartum Atopobium vaginae bacteremia.

We report the first case of spontaneous intrapartum Atopobium vaginae bacteremia identified by 16S rRNA gene sequencing. The bacterium was misidentified by RapID ANA II, API Rapid ID 32A, and matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). The likely source of bacteremia was the female genital tract. In invasive infections caused by A. vaginae, β-lactams and clindamycin are the antibiotics of choice, as most strains are resistant to metronidazole.
