Fig 1.
Raw FT-IR data of six Listeria species.
L. monocytogenes, L. grayi, L. innocua, L. ivanovii, L. seeligeri, L. welshemeri.
Table 1.
Listeria species distribution and percentage of correctly identified spectra.
Due to Listeria monocytogenes’ role in foodborne illness, there are a disproportional number of these isolates tested.
Fig 2.
Raw FT-IR data showing three serogroups of Listeria monocytogenes.
All strains were grown at 30°C. The spectral window shown is from x-minimum to 4,000 cm-1.
Table 2.
Eleven serovars of Listeria monocytogenes were used to form multiple artificial neural networks.
Percentages show correct identification. Groupings based on somatic O antigens and trends in public safety.
