pulsed-field gel electrophoresis applied for comparing listeria monocytogenes strains involved in outbreaks.recent food-borne outbreaks of human listeriosis as well as numerous sporadic cases have been mainly caused by listeria monocytogenes serovar 4b strains. thus, it was of interest to find out whether a certain clone or a certain few clones were responsible for these cases and especially for outbreaks. we used pulsed-field gel electrophoresis of large chromosomal dna restriction fragments generated by apai, smai, or noti to analyse 75 l. monocytogenes strains isolated during six major and eight sm ...19938500010
multilocus enzyme electrophoresis typing of new zealand listeria monocytogenes isolates.eighty-five strains of listeria monocytogenes, comprising 74 strains isolated from the environment, humans, animals and foods in new zealand; 10 strains from similar sources in denmark, and one reference strain, were studied using multilocus enzyme electrophoresis (mee). fifty-five electrophoretic types (ets) were identified among the 85 strains, most (71%) of which were represented by only one isolate. the 74 new zealand isolates produced 45 ets, most (67%) of which were represented by only one ...19968652343
