A collection of 218 strains of Burkholderia cepacia (including 18% strain replicates) was assembled from organic soils, decayed onions, and clinical sources. Each strain was characterized for virulence to onion, catabolic ability using the Biolog GN microtiter plate, and several other behaviors. Overall test reproducibility was estimated at 98%. The results obtained using the Biolog GN system corresponded well to those obtained using standard methods. Three coefficients of resemblance (Gower similarity, pattern difference, and Jaccard similarity) were calculated and clustered by the group-average method. The sorted matrices and phenograms, while giving evidence of an underlying phenetic structure to the B. cepacia nomenspecies, gave little evidence of sorting by broad source of isolation. Strains isolated from within fields or samples were frequently found to be similar, however, strains isolated from fields with similar cropping histories were not. The Gower-transformed centroids of ordained clusters were projected in a principal coordinate system and estimates of disjunction were calculated. Strains of B. cepacia were shown to be non-uniformly distributed in taxonomic space. Strains isolated by serial dilution on onion slices formed a tight phenetic cluster which includes the type strain of the nomenspecies and that of a synonymous group (Pseudomonas multivorans); the strains in this phenon were generally virulent to onion and were partially differentiated from others by pectolytic behavior and by the production of diffusible pigment on King's medium A. Further characterization should better resolve the taxonomy of the nomenspecies.
