Mc. Claros et al., Occurrence of Bacteroides fragilis enterotoxin gene-carrying strains in Germany and the United States, J CLIN MICR, 38(5), 2000, pp. 1996-1997
Ninety-three Bacteroides fragilis isolates from different geographic locati
ons were analyzed for the presence of an enterotoxin-encoding gene. It was
shown that blood culture isolates were more likely to carry this gene than
strains from other sources. All enterotoxin-positive strains belonged to th
e PCR fingerprint group I.
