Evidence of Compartmentalization.

aSamples of just plasma or just gut isolates having >70% of 1000 bootstrap replicates supporting an independent cluster, NS  =  not significant.
bAssociation Index. values <0.1 are highly significant for compartmentalization.
cSlatkin-Maddison migration test. “1” indicates a single migration event consistent with compartmentalization, text following indicates the direction of the migration event between plasma and gut. “multiple” indicates multiple migrations or free exchange of sequences between plasma and gut consistent with lack of compartmentalization.
