STX1A and infection: Sequences of Stx1 and Eagg gene fragments identified in this study were related to reference strains associated with infections such as hemolytic uremic syndrome (HUS) and diarrhea in patients from Egypt, South Africa, China, Japan, USA, and the UK [66,67,68,69,70,71,72], suggesting that Stx1 and Eagg strains found in this study may pose a threat to human health.
