I had this question yesterday on UW, GBS is the most common cause of neonatal sepsis, followed by E. coli, and lastly Listeria.

MM this is a nice question
Late Onset Sepsis is defined as sepsis occurring from the 4 to the 30 day post natal period.

According to Medscape there is an increase in S.epidermiditis infections, along with e.coli and pseudomonas, and a decline in GBS, the blame here is put towards the quality of the care the child is receiving..

http://emedicine.medscape.com/article/978352-overview

Ill attach and tiny article that also states the same fact.

I would pick staph yeah.. 3 sources indicating that it would be the most common cause can overrule Uworld.. besides it makes sense.. because the fault isnt in the mommy's vagina zoo, but rather in the caretakers like the nurse, the pediatrician, the intern and the medical student whom still dont know that washing your hands prevents nosocomial infections.

Exactly

Early onset sepsis (within 72 hours)---> GBS (pneumonia)

Late onset sepsis (after 72 hours) ---> Staph aureus (Meningitis)
