Shiga toxin-producing Escherichia coli (STEC) infection can cause simple diarrhoea but also life-threatening haemolytic and uraemic syndrome (HUS) in infants. Diagnosis is based on amplification of genes encoding the Shiga toxin (stx) on stools.1 The increasing ability to detect STEC due to the availability of multiplex PCR raises questions concerning the interpretation by clinicians of a positive PCR for patients with acute diarrhoea. Therefore, knowledge of the rate of asymptomatic carriage among young infants is needed. We assessed the rate of STEC carriage in a large cohort of children less than 2 years old, at risk of HUS in France, irrespective of their modality of care.

This work is an ancillary study of a longitudinal survey of faecal Enterobacterales antimicrobial resistance performed in children aged 6–24 …
