Probably, there would be a lack of consensus on the answer to this question, if a cross-section of clinical microbiologists were asked to respond, with the majority stating that all enterococcus isolates from blood cultures should be speciated. I hold what would be most likely a minority opinion. My lab does not routinely speciate enterococcal isolates from any body site since speciation is primarily of epidemiological interest or if there is a vancomycin-resistant enterococcus, in order to separate VanA or VanB strains from VanC strains. Others would contend that isolates from blood cultures should be fully identified because of the significance of the body site and as a means to verify the susceptibility profile.
