Phylogenetic tree showing the genetic relationships of the five isolates from Korean infant stools with the closest sequences identified in GenBank by BLAST.

Neighbor-joining analyses were conducted with the Jukes and Cantor model using the PHYLIP package [68]. The sequence of Paenibacillus jamilae CECT 5266^T (AJ271157) served as the outgroup. Solid circles indicate that corresponding nodes were also recovered using maximum-likelihood [69] and maximum-parsimony [70] trees. Bootstrap values (expressed as percentages of 1,000 repetitions) >70% are indicated at each node. Bar, 0.01 substitutions per nucleotide position.
