This is not the first report of bagpipe fungal pneumonia.

John Shone, 77, a Glaswegian, spent a month in the hospital with pneumonia and lost 21 pounds. After antibacterial treatment failed, a doctor told him he was dying, and then asked about his hobbies. When his son brought in his bagpipes, two types of fungi — rhodotorula and fusarium — were cultured. Mr. Shone acknowledged in a telephone interview that he had not cleaned his bag since being invited 18 months ago to play for a master piper, Donald MacPherson.
