Group B Streptococcus (GBS) is a gram-positive bacterium that normally parasitizes human urogenital tract and lower digestive tract. The infection rate in healthy people can reach 35%. Infections in healthy people are not pathogenic, but GBS, which colonizes the reproductive tract of women, can be vertically transmitted to the new born during delivery, causing neonatal septicaemia, meningitis and pneumonia even neurological sequelae. Researches have shown that GBS is not only one of the main pathogenic bacteria of neonatal infection, but also can lead to infection of pregnant women, causing amniotic cavity infection, premature rupture of membranes, puerperal infection and so on..

By applying real-time fluorescence quantitative PCR technology, this kit is characterized by high sensitivity, good specificity, short time and easy operation. It contains internal standard to monitor the whole process of the experiment to avoid false negative result.
