[Numerical analysis of telluric nonfermenting Gram-negative bacteria].

A numerical analysis was carried out from a set of 165 telluric Gram-negative bacterial strains. The results allowed to join up 130 of them divided into eight phenons. Two of these phenons represent on their own 70% of the classified strains. The first of these phenons (52 strains) can be assimilated to the genus Pseudomonas in the fluorescent group; the second one (41 strains) offers some analogies with the Acinetobacter. A representative strain type of the latter phenon was retained for later taxonomic comparisons.
