Differentiation of Listeria monocytogenes, Listeria innocua, Listeria ivanovii, and Listeria seeligeri by pulsed-field gel electrophoresis.

By P J Howard, K D Harsono and J B Luchansky


Clamped homogeneous electric field analysis of Listeria DNA with ApaI, AscI, SmaI, or NotI revealed species- and serotype-specific differences in genomic fingerprints. Clamped homogeneous electric field analysis may prove useful, therefore, in epidemiologic studies. Also, the summation of individually sized AscI fragments of genomic DNA from L. monocytogenes serotype 4b 101M and Scott A indicated genome lengths of 2,925 and 3,046 kb, respectively
