Bacteria Gram Positive Infection in BPH Patient

A previously healthy 73-year-old man with benign prostatic hyperplasia comes to the physician because of a 2-day history of pain with urination and 12-hour history of fever and chills. His temp is 38.3C (101F). PE shows moderate tenderness of the left flank. UA shows 50 to 100 WBC/hpf. Culture of urine gowns 100,000 colonies/ml of gram-positive organism. Which of the following is the most likely causal organism?

A) Enterococcus faecalis
B) Escherichia coli
C) Shigella dysenteriae
D) Staphylococcus aureus
E) Streptococcus pyogenes (group A)

Please answer. I know that D is wrong.

Save It!

But the q said that the organism is GRAM POSITIVE. Neither E. Coli nor Enterococcus are gr+.
I think E might be correct. but I'm not sure.
