FIG. 4.

Cluster dendrogram of Australian L. longbeachae isolates generated from SfiI restriction fragments separated by PFGE and analyzed with the program GelCompar ver 4.1. Similarity of >65% and more than a four-band difference in the band pattern divide the different types and clades. Subtype divisions have >88% similarity and band pattern differences of two or three bands. The type strain for L. longbeachae serogroup 1 was designated pulsotype B3, and the type strain for L. long-beachae serogroup 2 was designated pulsotype LL2. Isolates LL1 (i to vi) are representative internal controls of ATCC 33462, which were run on separate PFGE gels.
