Abstract

Pseudomonas aeruginosa was isolated in 22.2% of 305 intensive care unit environmental cultures. A high genetic heterogeneity (18 pulsotypes) was evident. Taps and related surfaces were a stable reservoir for certain pulsotypes. The 15.4% of the P aerugi-Mosa-positive cultures were polyclonal. Different colony morpho-types should be assayed in surveillance studies.
