Phylogenetic analysis of isolates of Family Enterobacteriaceae using partial sequences of 16S rRNA gene. a Isolates were subjected to AluI digestion followed by amplified ribosomal DNA restriction analysis (ARDRA) revealed 4 genotypic groups. b Phylogenetic tree constructed with MEGA6 based on ARDRA. The optimal tree was built using Neighbor-Joining method (sum of branch length = 0.2448)
