Lachaud L, et al. – Researchers constructed and evaluated a reference mass spectral library (MSL) for Leishmania isolates, accessible through a free web–based application (mass spectral identification, MSI), was constructed and tested. The tested application was reliable, with identification results comparable to those obtained with reference methods, but with a more favorable cost–efficiency ratio. This free online identification system relied on a scalable database and could be implemented directly in the user's computers.
