Which gram positive cocci is responsible for neonatal infections?

Streptococcus agalactiae, also known as Group B Streptococcus (GBS), is the gram-positive cocci most commonly associated with neonatal infections. This bacterium is part of the normal flora present in the gastrointestinal and genitourinary tracts of pregnant women. However, during delivery, it can be transmitted to the newborn, leading to serious infections such as sepsis, pneumonia, and meningitis.

The significance of Streptococcus agalactiae in neonatal infections is well-established, and routine screening for GBS in pregnant women is recommended to identify those who might carry the bacterium. These women can then receive intrapartum antibiotic prophylaxis to significantly reduce the risk of transmission and subsequent infections in the newborn.

In contrast, while Staphylococcus epidermidis and Staphylococcus aureus may cause infections in neonates, they are not the primary bacteria linked to the high incidence of neonatal infections. Staphylococcus epidermidis typically causes infections related to intravenous catheters and prosthetic devices. Staphylococcus aureus can lead to various infections, but it does not specifically target neonates in the same way as GBS. Streptococcus pyogenes is more commonly associated with conditions such as pharyngitis and
