Which Was the Real Guilty Party: Staphylococcus aureus, Staphylococcus pseudintermedius, Pasteurella multocida or All of Them?

I read with great interest the case report of McPherson et al1 that recently appeared in your Journal. They reported a case of epicardial abscess in a relatively immunocompetent patient. Abscess culture yielded Pasteurella multocida, which was identified as the causative agent. Previously obtained blood cultures yielded Staphylococcus aureus and Staphylococcus pseudintermedius. I have a few comments regarding the causative agent(s) of epicardial abscess in this case.
