Discrepant results between bacterial isolate identification by phenotype and isolate identification by genotype

Phenotypic Identification	Genetic Identification
Enterobacter cloacae	Escherichia coli
Pseudomonas aeruginosa	Salmonella enterica
Staphylococcus spp.	Enterococcus faecalis
Coagulase Negative Staphylococci	Enterococcus faecalis
Aeromonas hydrophila	Aeromonas punctata
Citrobacter freundii	Citrobacter murliniae
Enterococcus raffinosus	Enterococcus avium
Enterococcus raffinosus	Enterococcus avium
Staphylococcus intermedius	Staphylococcus pseudintermedius

Of the 46 cultured bacterial isolates that were cross-checked using DNA testing to verify identification, discrepancies in the identification of the isolate were present 9 times. The 9 discrepant isolates are listed above. The biochemically-determined taxonomic classification determined by culture phenotype is in the left column, and the molecularly-determined species classification by DNA 16S analysis is in the right column.
