The Raman spectroscopy data that was used in this study to
generate molecular “whole-organism fingerprints” [25e27] also
provided information on the molecular content of AHPND-causing
bacteria cells. The Raman spectra in Fig. 2 show bands representing
the major cell components, including proteins (1003 cm1 and
1659.9 cm1), nucleic acids (782.9 cm1), lipids (1253.7 cm1) and
carbohydrates/lipids (1449.5 cm1) [27,28]. We observed a slight
increase in the intensity of the Raman band of the AHPND-causing
strain 5HP located between 850 and 950 cm1, although the
