  • a +, positive; + or (+), positives and late positives together totalling 90% or more; −, negative; V, variable; ND, not done. Data for Pseudomonas fulva are from reference 27. Data for Pseudomonas putida, Pseudomonas luteola, and Pseudomonas oryzihabitans are from reference 3.

  • b The positive oxidase test result is based on only three strains studied by Uchino et al. (27).
