a
Numbers in parentheses are percentages of strains among each insertion site.
b
Numbers in parentheses are percentages of strains among each clinical collection.
c
One isolate of ribotype IX harbored two PAI IIJ96-like domains inserted in pheU and leuX.
d
The two UPEC reference strains J96 and AD110 have their PAI IIJ96 inserted in pheU with a papGIII allele.
e
By the Fisher test, P was <0.05 in a comparison with values for meningitis and UTI isolates.
