Phylogenetic analysis of the translocating isolate S. marcescens AS02 with 20 related bacteria. The phylogenetic relationships were inferred from the alignment of 1,508 bp of 16S rRNA gene indicating the positions of S. marcescens AS02 relative to selected Serratia species and other genera within the family Enterobacteriaceae. The evolutionary history was inferred by using the neighbor-joining method conducted in MEGA7 software. A sequence of Proteus mirabilis (a member of the Enterobacteriaceae family) was used as the outgroup. Bootstrap values (percentages of 1,000 tree replications) greater than 40% are displayed at the nodes. Sequence GenBank accession numbers are shown in parentheses. (Bar, 0.005 substitutions per nucleotide position.)
