title: A numerical taxonomic study of fluorescent Pseudomonas strains isolated from natural mineral waters.
abstract: Forty-six strains of fluorescent pseudomonads, isolated from natural mineral waters, together with 12 strains from clinical material and 44 reference strains, were phenotypically classified by 281 characteristics. The data were processed by the Dice similarity coefficient and unweighted pair group algorithm with arithmetic averages. Eight clusters were defined at the 62% similarity level. Clusters I, II and IV were further divided into nine subclusters. Virtually all the mineral water strains fall into three groups: Ib (eight strains), IIa (14 strains) and V (16 strains). Subclusters Ib and IIa included natural mineral water strains only. Cluster V contained 13 mineral water strains and three culture collection strains of Pseudomonas fluorescens biovar III. DNA/DNA hybridization studies are needed to define the taxonomic status of these three groups within the genus Pseudomonas.
