GBS in meningitis
I found this on Sepsis between late onset and early onset indicating E would be the answer.
Late onset: Late-onset sepsis is usually acquired from the environment (see Infections in Neonates: Neonatal Hospital-Acquired Infection). Staphylococci account for 30 to 60% of late-onset cases and are most frequently due to intravascular devices (particularly umbilical artery or vein catheters). http://www.merck.com/mmpe/sec19/ch279/ch279m.html
