A large increase in Shiga toxin-producing Escherichia coli O26: in England, 2014–2021

In a publication (Rodwell et al., 2023 The epidemiology of Shiga toxin-producing Escherichia coli O26:H11 (clonal complex 29) in England, 2014–2021. Journal of Infection, vol 86, issue 6, June 2023, 552-562) it is shown that in England, the number of cases of Escherichia coli (STEC) serotype O26:H11 belonging to clonal complex 29 (CC29) has increased over the last 10 years, with the number of notifications in 2021 being eight times that recorded in 2013. This increase is attributed to the increasing number of local hospital laboratories in England that have adopted a PCR approach to GI diagnostics, facilitating their capacity to detect non-O157 STEC serotypes, including STEC O26:H11. However, the PCR implementation attribute to only part of the increase. There has been a year-on-year increase in the notification of cases of STEC O26:H11 in England, except for 2020, when COVID restrictions most likely impacted numbers. @ https://www.sciencedirect.com/science/article/pii/S0163445323002062?
