Identification of Contaminated Cells with Viruses, Bacteria, or Fungi by Fourier Transform Infrared Microspectroscopy

Table 1

Changes in peaks position at 857 and 1650 cm⁻¹ as a result of Vero cells infection with HSV-1 or contamination with E. coli or fungi.

Sample	Wavenumber (cm^−1)
Vero	1650 ± 1.2	857 ± 0.6
Fungi	1651 ± 1.1	858 ± 1.1
Bacteria	1657 ± 1.6	857 ± 0.9
Vero + bacteria	1656 ± 1.8	856 ± 0.5
Vero + fungi	1651 ± 2.1	857 ± 0.8
Vero + HSV	1649 ± 1.2	853 ± 0.5

Vero cells were infected with 1 moi of HSV-1 or contaminated with E. coli or fungi. At 24 h later the different cell cultures were examined by FTIR microscopy. The results are means ± SD, (𝑛=5).
