Fig. 2From: Genomic analysis of Listeria monocytogenes from US food processing environments reveals a high prevalence of QAC efflux genes but limited evidence of their contribution to environmental persistenceA QAC efflux genes were unevenly distributed among clonal complexes. B Clonal complexes were associated with different facility types. The 20 most common clonal complexes are presented and the number of isolates for each clonal complex (n) is noted at the top of the figure. Clonal complexes are clustered by the facility type that had the most isolates for each clonal complexBack to article page
