unusual facts about Shiga toxin


Stec

Shiga toxin producing E. coli (STEC), sometimes called Verotoxin-producing Escherichia coli


Escherichia coli O104:H4

Genome assembly and copy number analysis both confirmed that two copies of the Shiga toxin stx2 prophage gene cluster are a distinctive characteristic of the genome of the O104:H4 outbreak strain.

Analysis of genomic sequences obtained by BGI Shenzhen show that the O104:H4 outbreak strain is an enteroaggregative E. coli (EAEC or EAggEC) type that has acquired Shiga toxin genes, presumably by horizontal gene transfer.
