Deep vaginal swab: Streptococcus agalactiae – Shipped May 16, 2016

Participants were expected to isolate, identify, and report Streptococcus agalactiae.
MAIN EDUCATIONAL POINTS from M161-2
- Postpartum endometritis occurs as a polymicrobial infection of the endometrium caused by inoculation of the uterine cavity with indigenous aerobic and anaerobic bacterial cervicovaginal flora.
- The utility of culture of vaginal, cervical, and endometrial samples in patients suspected of postpartum endometritis is controversial, and may not be routinely performed by some laboratories, because of the polymicrobial etiology underlying this infection and the difficulty in obtaining an uncontaminated specimen.
