  • a Data for members of the B. cepacia complex, B. gladioli, and R. pickettii from reference 42; data for Pandoraea spp. from reference 20; data for A. xylosoxidansfrom references 52 and 111; and data for S. maltophilia from references 27, 80, and 111.

  • b +, 90% or more of the strains investigated yielded a positive reaction; −, 10% or fewer of the strains investigated yielded a positive reaction; v, between 10 and 90% of the strains investigated yielded a positive reaction; NK, not known. The numbers of strains investigated were 23 (B. cepaciagenomovar I), 109 (B. multivorans), 139 (B. cepacia genomovar III), 27 (B. stabilis), 36 (B. vietnamiensis), 9 (B. cepacia genomovar VI), 18 (B. ambifaria), 27 (B. gladioli), 32 (Pandoraea spp.), and 12 (R. pickettii).
