Karyotype determination and gene mapping in two clinical isolates of Penicillium marneffei.

Electrophoretic karyotypes from two clinical isolates of Penicillium marneffei were derived using contoured-clamped homogeneous electric field (CHEF) gel electrophoresis. Five chromosome-sized DNA fragments were resolved from each isolate. Chromosomal length polymorphisms were evident among the three largest molecules.
