a
Each digit represents the number of exact tandem repeats at each locus. A zero indicates deletion of the ETR-A locus.
b
Number of cultures which were typed by VNTR. Not all cultures were available for analysis.
c
Number of patients with presumptive-false positive cultures.
d
Indication of whether VNTR data were available for the presumed source of contamination.
e
Number of patients after false-positive data were excluded but with extrapolated source data included (latter data in boldface).
f
VNTR profiles associated with two patients.
