Thumbnail of Random amplified polymorphic DNA fingerprinting (RAPD) types generated by arbitrarily primed PCR. Lanes 5-8 show results for the four index strains of the atypical Chryseobacterium meningosepticum, 96, 97-1, 97-2, and 97-3, respectively; lanes 1-4, four clinical isolates of C. meningosepticum from Canada; lanes 9-10, two clinical isolates of B. cepacia; lane 11, P. aeruginosa strain P1; and lane 12, clinical isolate of K. pneumoniae. Lane M shows the 1-kb DNA ladder.
