What Is Group B Strep?

Group B Streptococcus (GBS), scientifically known as Streptococcus agalactiae, is a type of bacteria that can be found in the intestines and the lower genital tract of healthy adults. While it is typically harmless in adults, it can pose serious health risks to newborns, leading to infections that can be life-threatening. Understanding GBS is crucial for expectant parents and healthcare providers alike.

GBS is one of the leading causes of bacterial infections in newborns, particularly in the first week of life. It is estimated that about 1 in 4 pregnant women carry this bacteria in their bodies. Most of the time, these women do not experience any symptoms, but the bacteria can be passed to the baby during delivery, which can lead to severe complications.

How Is Group B Strep Transmitted?

The transmission of Group B Streptococcus typically occurs during labor and delivery. If a mother is a carrier, the bacteria can be present in her birth canal, and the baby can be exposed during the birthing process. This is why screening for GBS is a standard practice in many healthcare settings, usually performed between the 35th and 37th weeks of pregnancy.

Risk Factors for Group B Strep Infections

While any newborn can be at risk for GBS infection, certain factors can increase the likelihood:

• Premature birth: Babies born before 37 weeks of gestation are at a higher risk.
• Low birth weight: Infants weighing less than 5.5 pounds are more susceptible.
• Prolonged rupture of membranes: If the amniotic sac breaks more than 18 hours before delivery, the risk increases.
• Maternal fever during labor: A fever can indicate an infection, raising the risk for the baby.

Symptoms in Newborns

Recognizing the symptoms of Group B Streptococcal infections in newborns is vital for prompt treatment. Symptoms can appear within the first week of life (early-onset) or up to three months after birth (late-onset). Here are some common signs to watch for:

Early-Onset Symptoms

Early-onset GBS infections typically manifest within the first 24 to 48 hours after birth. Symptoms may include:

• Difficulty breathing: Rapid or labored breathing can be a sign of respiratory distress.
• Temperature instability: Newborns may have a low or high body temperature.
• Feeding difficulties: Refusal to feed or poor feeding can indicate illness.
• Unusual lethargy: Excessive sleepiness or difficulty waking up can be concerning.
• Skin rash: A rash or discoloration of the skin may occur.

Late-Onset Symptoms

Late-onset GBS infections can occur between one week and three months after birth. Symptoms may include:

• Fever: A sudden increase in body temperature can be a warning sign.
• Seizures: Neurological symptoms such as seizures may indicate a serious infection.
• Difficulty feeding: Similar to early-onset symptoms, feeding issues can persist.
• Changes in behavior: Increased irritability or decreased responsiveness may be observed.

When to Seek Medical Attention

If you notice any of these symptoms in your newborn, it is crucial to seek medical attention immediately. Early diagnosis and treatment can significantly improve outcomes for infants with Group B Streptococcal infections.

Causes of Infection

Group B Streptococcal infections in newborns are primarily caused by the bacterium Streptococcus agalactiae, commonly known as Group B Streptococcus (GBS). This bacterium is a part of the normal flora found in the intestines and the lower genital tract of many healthy adults. However, it can pose serious risks to newborns, especially if transmitted during childbirth.

Transmission During Labor and Delivery

The most common way that newborns acquire Group B Streptococcus is during labor and delivery. If a mother is a carrier of GBS, the bacteria can be passed to the baby through the birth canal. This transmission can occur even if the mother shows no symptoms of infection. In fact, approximately 10-30% of pregnant women carry GBS in their vagina or rectum without any complications.

Intrauterine Infection

In some cases, GBS can also infect the baby while still in the womb. This can happen if the bacteria ascend from the vagina into the uterus, leading to conditions such as chorioamnionitis (infection of the amniotic fluid and membranes). This intrauterine infection can increase the risk of early-onset GBS disease in newborns.

Postnatal Infection

While less common, it is also possible for a newborn to develop a Group B Streptococcal infection after birth. This can occur through contact with infected individuals or contaminated surfaces. Newborns are particularly vulnerable due to their immature immune systems, making it crucial to maintain a clean environment and practice good hygiene.

Risk Factors for Newborns

Understanding the risk factors associated with Group B Streptococcal infections in newborns is essential for prevention and early intervention. Several factors can increase the likelihood of a newborn contracting this infection.

Maternal GBS Status

The most significant risk factor is whether the mother is a carrier of GBS. Pregnant women are typically screened for GBS between 35-37 weeks of gestation. If a mother tests positive, she may be given antibiotics during labor to reduce the risk of transmission to the baby.

Preterm Birth

Newborns born prematurely (before 37 weeks of gestation) are at a higher risk for GBS infections. Their underdeveloped immune systems make it more challenging for them to fight off infections. Additionally, preterm infants may have a higher likelihood of being exposed to GBS during delivery.

Prolonged Rupture of Membranes

If a pregnant woman experiences a prolonged rupture of membranes (water breaking) for more than 18 hours before delivery, the risk of GBS infection increases. This extended exposure can allow bacteria to enter the uterus and potentially infect the baby.

Previous GBS Infection in a Newborn

If a mother has had a previous baby who developed a Group B Streptococcal infection, her subsequent newborns are at an increased risk. This history can indicate a higher likelihood of GBS colonization in future pregnancies.

Maternal Fever During Labor

A maternal fever during labor (≥ 100.4°F or 38°C) can also be a risk factor for GBS infection in newborns. Fever may indicate an infection, which can increase the chances of the baby contracting GBS during delivery.

Other Health Conditions

Certain health conditions in the mother, such as diabetes or urinary tract infections, can also elevate the risk of GBS transmission to the newborn. These conditions may compromise the mother’s immune system, making it easier for GBS to proliferate.

In summary, Group B Streptococcal infections in newborns can be serious, but understanding the causes and risk factors can help in taking preventive measures. Pregnant women should discuss their GBS status with their healthcare providers to ensure the best outcomes for their babies. 🍼✨
