A 28-year-old man presents to A&E with high fever (40°C), productive
purulent cough and low blood pressure. His mother reports a laboratory
confirmed influenza infection two weeks ago, and that he was rather well until
earlier this morning when he suddenly developed high fever. A chest CT scan
reveals lung abscesses with cavity formation. Sputum Gram stain reveals
abundant neutrophils along with Gram-positive cocci arranged in clusters, which
on culture isolates were coagulase and catalase-positive.

Which infectious agent and associated factor are most likely responsible
for this patient’s symptoms?
