a
HUS, hemolytic-uremic syndrome; NK, not known.
b
Presence of small lysis plaques instead of a confluent lysis area was detected.
c
Presence of a blurred halo around the lysis area was detected.
d
Clear lysis with colonies in the lysis plaque was seen.
e
The E. coli K-12 strain was used as a control strain.
f
−, nondetectable lysis in the spot area; ++++, clear lysis in the spot area; +++, minimally opaque lysis in the spot area; ++, moderately opaque lysis in the spot area; +, maximally opaque lysis in the spot area.
