摘要：
Chromosomal DNA of Listeria monocytogenes strains was digested with SmaI restriction enzyme, and the resulting fragments were separated by pulsed-field gel electrophoresis. Distinctive banding patterns were obtained from the strains of major foodborne disease serotypes 1/2a, 1/2b and 4b. Matched sets of clinical and food isolates revealed close similarity among strains from a given episode and distinct differences among strains from separate episodes. © 1994 Academic Press Limited.
