Use cases
MALDI-ToF and FTIR have proven its power to type microbes beyond simple species ID. The data resulting from use of the current MALDI-TOF or FT-IR spectra, after it’s use to obtain a pathogen ID, can additionally (without any new sample run ) be used for epidemiology studies.
Just import the MALDI-ToF and/or FTIR data file into Clover Biosoft software with our import data tool and you can immediately extract additional pathogen information such as clone/subspecies detection or identification of specific antibiotic resistance markers in Klebsiella spp.
We have collaborated with different reference institutions around the world to produce the following list of “classifiers”: easy to use classification tools to help you further characterize a specific pathogen complementing its previous ID result from MALDI-ToF and/or FTIR.
And we are constantly updating this list with new classification responses to epidemiological outbreaks/emergencies such as the hypervirulent Klebsiella pneumoniae ST23 (consult us for more information about this development)
Please note: all of this classification solutions are immediately available on any paid subscription to our Clover Biosoft MALDI Masster, FTIR Prodigy or Spectra Maestro licenses.
