CHROMagar™ StrepB

The Group B Streptococci (GBS), also known under the name of Streptococcus agalactiae are an important cause of serious neonatal infection. A higher risk exists for newborns whose mothers are colonized with GBS in the genital areas shortly before birth.

Detecting vaginal colonization by GBS in pregnant women is the most effective strategy to prevent neonatal infections. Studies indicate approximately 10-30% of pregnant women are colonized with GBS.

Worldwide, official guidelines recommend a prenatal screening of GBS between the 34th and the 38th weeks of pregnancy. This screening allows to determine the need of intrapartum antibiotic prophylaxie.

CHROMagar™ StrepB is a new chromogenic medium for the screening of S.agalactiae.

This new tool features the following advantages:

• Easier reading thanks to a higly specific and sensitive mauve colony colouration
• detection of GBS, including non-haemolytic strains, with sensitivity close to 100 %
• Differenciation of GBS from other bacteria by selective inhibition or by counter-colouration
• Results in 18-24h
• Incubation in aerobic conditions
