Enterotoxigenic and nontoxigenic Bacteroides fragilis strains isolated in Brazil
The presence of enterotoxigenic Bacteroides fragilis and nontoxigenic
B. fragilis (NTBF) among 109 strains isolated from 1980-2008 in Brazil
were investigated by PCR. One strain, representing 0.9% of the total
analyzed strains, harbored the bft gene which was identified as bft-1
isoform based on PCR-RFLP and sequencing. Forty-nine strains (44.9%)
exhibited the NTBF pattern III which possesses the flanking region
required for pathogenicity island acquisition in which the bftgene is
codified. These data reinforce the potential of B. fragilis as an
emerging enteropathogen in our country
