title: An electrophoretic molecular karyotype of a clinical isolate of Aspergillus fumigatus and localization of the MDR-like genes AfuMDR1 and AfuMDR2.
abstract: The molecular karyotype of a clinical isolate of Aspergillus fumigatus (10AF/86/10) was determined by contour-clamped homogeneous electric field gel electrophoresis. Five chromosomal bands were resolved by this method. The resolved chromosomes ranged in size from 1.7 to 4.8 Mb, and together constituted a total genomic size of at least 15.8 Mb. Southern analysis of the separated chromosomes located the position of two MDR-like genes, AfuMDR1 and AfuMDR2, on chromosomes III and IV, respectively. The methods described herein may enable the application of molecular karyotyping of A. fumigatus in epidemiologic surveillance studies.
