Group B streptococcal bacteria

The bacteria group B streptococci is a common organism that lives in the gastrointestinal tract and vaginal flora of about 30% of pregnant women.

This bacteria is harmless in most cases. It is only aggressive with newborns at the time of delivery, especially premature babies, so it is very important to take the test.

How is Group B streptococcal examination done?

The test is quick and simple; it consists of removing, with the aid of a cuff, samples of the culture of bacteria from the region of the vagina and the anus.

Then the specialist will check if the bacteria group B streptococci is living in the intimate region of the pregnant.

The result of the exam is in a few days. Experts recommend doing this exam in the last weeks of gestation, because the closer you are to the delivery, the more the vaginal flora will look like the time of delivery.

Exam in Brazil

In Brazil, the group B streptococcus is recommended by the Ministry of Health.

The body recommends that gynecologists perform this examination in all pregnant women, but in other countries, the examination is only indicated for groups of pregnant women at risk.

Positive result

According to doctors, between 15% and 20% of pregnant women present the presence of group B streptococcal bacteria.

The women who receive the positive diagnosis of this bacteria do not have to worry, because while the baby is in the uterus there is no chance of the bacterium infecting it, the risk only occurs when the baby is born, because at the time of delivery the bacteria can pass for the newborn.

If the pregnant woman is diagnosed with the group B streptococcal bacteria, she will be treated with antibiotics in the vein during labor, which reduces the risk of transmission.

The bacterial contamination rate for infants using prophylaxis is 0.3 to 0.4 cases per 1,000 live births.

One needs to be very careful not to get the baby contaminated because the newborn can develop meningitis and very severe pictures of widespread infection which can lead the infant to death.

The positive result in the group B streptococcus does not exclude the option of normal birth, this result is only to know which pregnant women will need antibiotics at the time of delivery.
