Cluster diagram of 50 Burkholderia cepacia complex isolates based on three principal components. Eleven of 13 isolates of B. cepacia were grouped together (encircled). Isolate number 32 (a), though identified as B. cepacia, has been placed far apart from rest of the isolates. Isolate number 45 (b), which was misidentified by MALDI-TOF MS as B. cenocepacia, was placed well outside the B. cepacia cluster. Isolate numbers 11 (c) and 44 (d), which were B. cenocepacia IIIB by multilocus sequence typing, were grouped along with the B. cenocepacia IIIA isolates.
