Laboratory practices and incidence of non-O157 shiga toxin-producing Escherichia coli infections

We surveyed laboratories in Washington State, USA, and found that increased use of Shiga toxin assays correlated with increased reported incidence of non-O157 Shiga toxin-producing Escherichia coli (STEC) infections during 2005-2010. Despite increased assay use, only half of processed stool specimen...

Zusammenfassung:	We surveyed laboratories in Washington State, USA, and found that increased use of Shiga toxin assays correlated with increased reported incidence of non-O157 Shiga toxin-producing Escherichia coli (STEC) infections during 2005-2010. Despite increased assay use, only half of processed stool specimens underwent Shiga toxin testing during 2010, suggesting substantial underdetection of non-O157 STEC infections.
