Table 2 Growth time in selective liquid media, time to identification after blood culture positivity, and number of concordant/correct identifications by the rapid method
Selective culture medium (selected category of microorganisms) | Mean growth time to reach a density of 0.5 McFarland (min–max) | Mean time to identification after BC positivity (min-max) | Number of correct/concordant identifications (%) |
