Me. Proctor et al., USE OF PULSED-FIELD GEL-ELECTROPHORESIS TO LINK SPORADIC CASES OF INVASIVE LISTERIOSIS WITH RECALLED CHOCOLATE MILK, Applied and environmental microbiology, 61(8), 1995, pp. 3177-3179
Pulsed-field gel electrophoresis established the linkage between recal
led chocolate milk and a multistate invasive listeriosis outbreak duri
ng a four-product recall period. Listeria monocytogenes isolates from
four hospitalized patients and an environmental dairy sample displayed
AscI restriction endonuclease digestion profiles identical to that of
the chocolate milk isolate.
