Respuesta :

The isolates would be classified as individual strains of the same species. 

The average nucleotide Identity (ANI) above 95% are considered of same species.

What is Average nucleotide identity?
Average nucleotide Identity is a method of comparing sequenced microbial genomes. It is used for prokaryotes. As, 12 new isolates from the human skin have 97% average nucleotide identity for shared orthologous genes , so they are classified as individuals strains of the same species. 

Therefore if you are studying 12 new isolates from the human skin, their average nucleotide identity for shared orthologous genes is 97%, then isolates would most likely be classified as individual strains of the same species.
