I have 4 species, by doing its 16srDNA analysis its showing match with shigella spp. after doing its MLST via enterobase plateform it shows me ST of E.coli. how I can know the species type of my samples?
Since Shigella spp. is just a subgenus of E. coli, you can use phenotype methods to confirm Shigella, such as antigenic and biochemical properties according to the Bergey's manual.
