Comparative evaluation of 5 different selective media for Group B Streptococcus screening in pregnant women

Diagn Microbiol Infect Dis. 2014 Dec;80(4):282-4. doi: 10.1016/j.diagmicrobio.2014.08.005. Epub 2014 Aug 29.


We compared the performances and the cost-effectiveness of 5 selective media for Group B Streptococcus (GBS) screening in vaginal samples from pregnant women. The usefulness of these media is unquestionable for GBS screening; the choice will depend largely on the laboratory organization.

Keywords: Chromogenic medium; Granada medium; Group B Streptococcus; MALDI-TOF MS; Streptococcus agalactiae; Vaginal screening.
