Isolation of Shiga toxin-producing Escherichia coli harboring variant Shiga toxin genes from seafood

Abstract

The results of this study showed the occurrence of STEC in seafood harboring one or more Shiga toxin genes. The detection of STEC by PCR may be hampered due to the presence of variant genes such as the <i>stx1d</i> in STEC. This is the first report of <i>stx1d</i> gene in STEC isolated from Indian seafood.
