R. Bonnet et al., NON-O157-H7 STX2-PRODUCING ESCHERICHIA-COLI STRAINS ASSOCIATED WITH SPORADIC CASES OF HEMOLYTIC-UREMIC SYNDROME IN ADULTS, Journal of clinical microbiology, 36(6), 1998, pp. 1777-1780
From August 1996 to May 1997, six verotoxin-producing Escherichia coli
(VTEC) strains were isolated from stool specimens of adults suffering
from hemolytic-uremic syndrome (HUS). All the isolates were stx(2) po
sitive and belonged to different serotypes: O6:H4, O91:H10, O91:H21, O
rough:H16, OX3:H-, and O nontypeable: H-. The enterohemolysin (Ehly)-
encoding genes were detected in two isolates, and none of the isolates
harbors the intimin (Eae) encoding gene. These findings suggest that
stx(2)-positive non O157:H7 VTEC is a major cause of HUS in adults and
that several sources of pathogens are responsible for local endemic i
nfections.
