Other DNABased Techniques

Genomic fingerprinting of Listeria DNA via pulsed-field gel electrophoresis (PFGE) was also found to discriminate between Listeria species.[22] Finally, the A511 phage, a broad host range bacteriophage specific for the genus Listeria, has been genetically engineered by the incorporation of the lux operon of Vibrio fischeri in its chromosome. The A511 luxAB phage transduces bacterial bioluminescence into infected cells, allowing a rapid and easy testing of contaminated food and environmental sample for the presence of viable Listeria cells.[23]
