Abstract
The phenotype characteristics of 100 strains of P. cepacia, mostly of hospital origin, were compared to those of the typical mother strain (ATCC 25416). The morphological, cultural and biochemical characteristics, nutritional characteristics (use of numerous organic compounds) and the antibiotypes (usually resistant to .beta.-lactamines, aminoglycosides, polymyxins, tetracycline and furans) are reported, together with differential diagnostic problems between P. cepacia and P. maltophilia (TTR+ methionine requirement), P. pseudomallei (LDC-, ODC-, ADH+, ONPG-) and Agrobacterium sp. (urease+, LDC-, ODC-, absence of exoenzymes and use of citrate and malonate). An original classification in 8 biovars permitted epidemiological marking of the strains and a study of their distribution.
