DMID 2016; pii: S0732-8893(16)30161-4.doi:10.1016/j.diagmicrobio.2016.06.001. [Epub ahead of print] Publication Key Takeaways
Inactivation and peptide extraction from mycobacteria in ≤ 5 minutes with subsequent identification to the species level using MALDI TOF MS and a log confidence cut-off of ≥ 1.7
The AFA method does not require extensive library construction, but rather can be utilized for the most part with the existing commercial database
The time savings and decreased cost of AFA-based inactivation and peptide extraction for MALDI-ToF MS identification provides the means for a rapid, standardized protocol which can be utilized easily by clinical laboratories
Agreement for all species considered together was 100% regardless of the number of spots tested using a log confidence score of ≥ 1.7 and the existing Bruker database<br>
