Overview

Group B Streptococcus (GBS) infection causes a variety of clinical presentations depending on the type of the affected subjects; therefore, the differential diagnosis of GBS infection varies based on the age of the patient and their health condition. Early-onset GBS infection in neonates might lead to pneumonia, meningitis, or sepsis and it must be differentiated from other types of infectious agents in this category of patients.

Differential Diagnosis

Shown below is a table summarizing the different pathogens that can cause meningitis in infants.

Age	Possible pathogens causing the bacterial meningitis
< 1 month	Streptococcus agalactiae Escherichia coli Listeria monocytogenes Klebsiella
1-23 months	Streptococcus pneumoniae Neisseria meningitidis Streptococcus agalactiae Haemophilus influenzae E. coli
