CHROMID^® Strepto B

Group B Streptococcus (GBS), or S. agalactiae, is a Gram-positive bacterium that is commonly asymptomatic in adults. For newborns, however, it can lead to serious – even deadly – health issues including sepsis, pneumonia, and meningitis. It is therefore critical to identify the approximately 25% of pregnant women who carry GBS in the genital tract. Administering antibiotics during labor can drastically reduce potential transmission of the disease to the baby during childbirth. The 2010 CDC guidelines for GBS testing list CHROMID^® Strepto B as a recommended commercially available chromogenic agar¹.

Optimized identification

Identification of all Group B Streptococci (GBS) is clear and easy with CHROMID^® Strepto B thanks to three chromogenic substrates that distinguish pale pink to red GBS colonies which are round and pearly after 18-24 hours incubation. The coloration makes it easy to see the colonies, even if there are few on a plate or if there are mixed cultures.

• Excellent performance for the GBS prenatal screening in terms of nutrient capacity and sensitivity of detection
• Detection of GBS strains, including non ß-hemolitic strains
• Selective inhibition of most bacteria not belonging to the species S. agalactiae, as well as yeasts
