Patient's question:
My wife is very excited about the baby's birth. After going through all the hardships, we finally arrived at our first baby. Although it was a difficult birth, the doctor said the baby is healthy. However, within two or three days, the baby started to experience recurrent fainting. The doctor said it was due to a Group B Strep infection in newborns. What kind of assistance is needed: What causes Group B Strep infection in newborns?Doctor's answer:
Early colonization of the patient with Group B Streptococcus (GBS) can lead to damage of the mucosal barrier when a respiratory infection occurs again, allowing GBS to take advantage and produce large amounts of GBS type III capsule polysaccharide antigen, or due to an increase in maternal autoantibodies. The onset of GBS osteomyelitis is caused by early-onset GBS bacteremia, which may be asymptomatic but can introduce bacteria into injured bone (e.g., the humerus), subsequently leading to localized osteomyelitis. The patient may have no systemic symptoms. Since the child has already produced a very small amount of antibodies, the decrease in type III-specific IgG antibodies in the blood can limit the infection to the metaphysis.
