Is Escherichia coli and Klebsiella pneumoniae closely related? Do both of them produce green sheen color on EMB agar? A strain doubted to be E. coli identified as K. pneumoniae even after performing all the biochemical tests. Complete genome comparison of identified strain shows 99% identity with E. coli but in BLAST results it shows as K. pneumoniae with no listed E. coli as identity. Any literature to support this?
