Clamped homogeneous electric field gel electrophoresis typing of Torulopsis glabrata isolates causing nosocomial infections

Thirty isolates of Torulopsis glabrata were examined by pulsed-field gel electrophoresis, which resolved 13 DNA pieces, allowing the identification of 12 types. Bands at 1,400, 1,200, 1,070, 1,025, 681, and 500 kbp were conserved. When applied to 18 isolates from an outbreak, 10 distinct types were identified by this technique. Seven patients had isolates which were identical.
