^aIf group B Streptococcus was isolated from >1 clinical site in the same patient, the most life-threatening or deepest site of infection was considered the “most serious” infected site.

^bBacteriuria with abnormal urinalysis results and antibiotic prescribed by the treating physician.

^cPatient with fluid surrounding the reservoir of a pain pump in the subcutaneous tissue (ie, seroma, resorbing hematoma, or abscess).
