Summary: | We report the frequency of the different diarrheagenic Escherichia coli
(DEC) categories isolated from children with acute endemic diarrhea
in Salvador, Bahia. The E. coli isolates were investigated by colony
blot hibridization whit the following genes probes: eae, EAF, bfpA,
St×1, St×2, ST-Ih, ST-Ip, LT-I, LT-II, INV, and EAEC, as
virulence markers to distinguish typical and atypical EPEC, EHEC/STEC,
ETEC, EIEC, and EAEC. Seven of the eight categories of DEC were
detected. The most frequently isolated was atypical EPEC (10.1%)
followed by ETEC (7.5%), and EAEC (4.2%). EHEC, STEC, EIEC, and typical
EPEC were each detected once. The strains of ETEC, EAEC, and atypical
EPEC belonged to a wide variety of serotypes. The serotypes of the
others categories were O26:H11 (EHEC), O21:H21 (STEC), O142:H34
(typical EPEC), and O?H55 (EIEC). We also present the clinical
manifestations and other pathogenic species observed in children with
DEC. This is the first report of EHEC and STEC in Salvador, and one of
the first in Brazil. |
