a
In the virulence profile-based dendrogram, 4 additional pyelonephritis isolates were placed outside the 2 main clusters (and 4 main subclusters).
b
P = 0.002, for prevalence of source group within indicated cluster or subcluster versus the rest of the population.
c
P ≤ 0.03, for prevalence of source group within indicated cluster or subcluster versus the rest of the population.
d
P ≤ 0.001, for prevalence of source group within indicated cluster or subcluster versus the rest of the population.
