Phylogenetic tree for Salmonella enterica serotype Enteritidis isolates from outbreak in Massachusetts, USA, 2018. The colored boxes on the left indicate 9 separate subclusters for the entire 84-isolate cluster, with confirmation of allele differences coming from PulseNet (https://www.cdc.gov/pulsenet/index.html). Eight subclusters yielded no epidemiologic data, resulting in the closure of those clusters. The ninth subcluster, in the green box (right), contains the isolates associated with the r

The colored boxes on the left indicate 9 separate subclusters for the entire 84-isolate cluster, with confirmation of allele differences coming from PulseNet (https://www.cdc.gov/pulsenet/index.html). Eight subclusters yielded no epidemiologic data, resulting in the closure of those clusters. The ninth subcluster, in the green box (right), contains the isolates associated with the restaurant cluster. Boldface indicates isolates from persons who ate at the restaurant; the star indicates the isolate from the food handler implicated in the outbreak.
