This study examined eight elderly patients without compromised immune systems who had Scedosporium fungus detected in their lungs. All patients had a condition called bronchiectasis and most had previously suffered from a lung infection called MAC disease. The researchers found that in most cases, the fungus was simply living in the lungs without causing active infection, though distinguishing between these two situations proved difficult. Only one patient was diagnosed with an active Scedosporium infection and required antifungal treatment with a drug called voriconazole.
