The Importance Of B Streptococcus Detection
The group B streptococcus is a gram-positive streptococcus with facultative anaerobic anaerobe. Prenatal screening for streptococcus B is particularly important because of the severity of symptoms and diseases related to pregnancy and newborn caused by streptococcus B infection. Delivery transmission is the main route of neonatal infection with group B streptococcus. Therefore, antibiotic prevention can effectively reduce the vertical transmission of group B
streptococcus to induce early neonatal invasive infection.
In the treatment of group B streptococcus, since the rate of infection in pregnant women is about 10%-30%, the prevention of antibiotic injection in all pregnant women will obviously lead to unnecessary use of antibiotics. Therefore, it is especially necessary to carry out group B streptococcus screening before pregnancy.
Mothers-to-be should pay attention to the detection of group B streptococcus
Group B streptococcus is a common strain, often residing in the vagina and rectum, and about 30% of women have group B streptococcus in their vagina. Group B streptococcus can be found in healthy women, which generally will not cause much impact, but can occasionally cause urethritis or produce vaginal secretions.
There is a real risk of finding streptococcus B in mothers-to-be. Because when the baby is passed through the birth canal, it may inhale the secretions and infect the B strep. Fetal babies are only 1 to 3 percent likely to be infected with the bacteria, but the effects on newborns are severe, causing sepsis, meningitis, pneumonia and so on in newborns, about 5 percent of whom will die. Even if newborns survive the infection they may have severe neurological sequelae, such as intellectual impairment, microcephaly, and deafness.
Chemtron biotech recommend testing at 35 to 37 weeks
It is suggest that it is preferable for that mother to perform vaginal group B streptococcus detection at the time of the pregnancy of 35-37 week in order to find out whether or not a group B streptococcus is carried out and to take appropriate action during childbirth. The doctor will use a sterile cotton swab to put into the vagina to pick up the vaginal secretions of the expectant mother, and then send the sterile swab to the laboratory for testing. If the test result is negative, it indicates that no group B streptococcus is present. If the test is positive, the doctor will inject the woman with antibiotics during childbirth and perform the necessary tests and treatment of the newborn.
