Phylogenetic context of Shiga toxin-producing Escherichia coli serotype O26:H11 in England.

ABSTRACT: The increasing use of PCR for the detection of gastrointestinal pathogens in hospital laboratories in England has improved the detection of Shiga toxin-producing Escherichia coli (STEC), and the diagnosis of haemolytic uraemic syndrome (HUS). We aimed to analyse the microbiological characteristics and phylogenetic relationships of STEC O26:H11, clonal complex (CC) 29, in England to inform surveillance, and to assess the threat to public health. There were 502 STEC belonging to CC29 isolated between 2014 and 2019, of which 416 were from individual cases. The majority of isolates belonged to one of three major sequence types (STs), ST16 (n=37), ST21 (n=350) and ST29 (n=24). ST16 and ST29 were mainly isolated from cases reporting recent travel abroad. Within ST21,
