Final answer:

S. agalactiae and E. coli are common causes of neonatal infections, while H. influenzae type b was prevalent before immunization programs. These bacteria play significant roles in neonatal health conditions.


Explanation:

S. agalactiae (Group B streptococcus) is the most common cause of neonatal meningitis, sepsis, and pneumonia in the United States. This encapsulated gram-positive bacterium can be found in the urogenital and gastrointestinal microbiota of humans.

E. coli is another leading cause of neonatal meningitis, along with group B streptococci. It is dominant in the intestinal tract and certain strains can lead to infections.

H. influenzae type b used to be a common cause of neonatal pneumonia, septicemia, and meningitis before routine immunization programs significantly reduced its incidence in developed countries.
