Which organism is not listed among the common causes of post-surgical endophthalmitis?

Explanation:
Post-surgical endophthalmitis is most often caused by organisms from the patient’s own surface flora, especially gram-positive cocci. The usual suspects are Staphylococcus aureus and Staphylococcus epidermidis, with Streptococcus species also commonly implicated. Listeria monocytogenes does not fit into these common culprits; it is a rare cause of endophthalmitis and is more typically linked to systemic or foodborne infections rather than postoperative intraocular infection. So Listeria monocytogenes is not listed among the common causes of post-surgical endophthalmitis.
