DNA fingerprinting of Aspergillus fumigatus isolates from patients with aspergilloma

Abstract

Fourteen sputum isolates of Aspergillus fumigatus from Glasgow, Scotland, including 12 isolates from patients with aspergilloma were DNA typed and compared to 31 previously typed isolates. Five isolates obtained over a period of 12 months from one aspergilloma patient were of four DNA types. Two isolates from another patient with aspergilloma were identical. One isolate each from five other aspergilloma patients showed five DNA types. Two DNA types, each shared by two aspergilloma isolates, were each identical to the DNA types from invasive aspergillosis isolates, one from Germany and one from the USA.
