Doctor's answer:
Neonatal sepsis refers to a systemic infection caused by pathogens invading the neonatal bloodstream and growing, multiplying, and producing toxins within it, with relatively high morbidity and mortality rates. Sepsis can be caused by various pathogens. Common ones include Staphylococcus aureus, Streptococcus hemolyticus, Streptococcus pneumoniae, Escherichia coli, Neisseria meningitidis, Pseudomonas aeruginosa, Proteus, Salmonella, and Klebsiella, among others. When the body's resistance declines, opportunistic pathogens or low-pathogenic bacteria, such as Staphylococcus epidermidis, may cause infection.
