MFGTX-ZSQR-GBS is used for the detection of Group B streptococcus, which may cause infection to pregnant women and infants.
Feature & Principle
-Liquid bacteria enhancement, specific chromogenic.
-Fully automated, high-throughput detection.
-Selective chromogenic medium ensures GBS growth.
-Easy to transfer GBS from medium.

What is group B Streptococcus?
Group B Streptococcus
Gram positive, beta hemolytic bacteria.
Common colonizer of human gastrointestinal and genitourinary tracts.
Recognized as causing disease in humans.
Causes serious desease in young infants, pregnant women.
Emerged as most common cause of sepsis and meningitis in infants <3 months.
Why it is important?
10% - 30% of women are GBS carries
What has U.S. done to prevent it?
1. Publish guidelines for prevention of perinatal group B streptococcal diseases
2. Universal screening of pregnant woman for GBS at 35 – 37 weeks gestational age
The recommendations from
（prevention of perinatal group B Streptococcal Disease, Revised Guideline from CDC, 2010）
