What Causes Strep B Positive In Pregnancy?

Group B streptococcus, also known as strep B, is a type of bacteria that can naturally reside in the genital tract of some women. While it is not fully understood why some women have this bacteria and others do not, it is important to note that being positive for group B strep during pregnancy is not a reflection of personal hygiene or lifestyle choices.

How Does Group B Strep Occur?

The presence of group B strep in the genital tract of pregnant women can be attributed to various factors, including the natural colonization of bacteria in the body. It is not always possible to pinpoint the exact cause of why some women have this bacteria and others do not, as it can occur without any specific reason.

Transmission Risk to the Baby

When a pregnant woman tests positive for group B strep, the main concern is the potential risk of transmitting the bacteria to the baby during delivery. While the chances of this happening are relatively low, it is essential for healthcare providers to take precautions to prevent any potential complications.

Preventive Measures

One of the primary ways to reduce the risk of transmitting group B strep to the baby is through the administration of antibiotics during labor. By receiving antibiotics, the bacteria can be effectively controlled, minimizing the chances of infection in the newborn.

Effects of Group B Strep on the Baby

If a baby is exposed to group B strep during delivery and develops an infection, it can lead to serious health complications, including sepsis, pneumonia, and meningitis. This is why early detection and preventive measures are crucial in reducing the risk of transmission.

Risk Factors

While the exact reason for the presence of group B strep in some pregnant women remains unclear, there are certain risk factors that may increase the likelihood of testing positive for the bacteria. These factors include a history of group B strep in previous pregnancies and preterm labor.

Testing and Diagnosis

Testing for group B strep is a routine part of prenatal care, typically conducted between the 35th and 37th week of pregnancy. The test involves swabbing the vaginal and rectal areas to detect the presence of the bacteria.

Treatment Options

If a pregnant woman tests positive for group B strep, the recommended course of action is to receive antibiotics during labor. This treatment helps reduce the risk of passing the bacteria to the baby and minimizes the chances of complications.

Consulting Your Healthcare Provider

If you have been diagnosed with group B strep during pregnancy, it is important to discuss your options with your healthcare provider. They can provide guidance on the best course of action to protect both you and your baby during labor and delivery.
