Shiga toxin-producing Escherichia coli (STEC) infections pose a significant public health challenge, characterized by severe complications including hemolytic uremic syndrome (HUS) due to Shiga toxin (Stx) production. Current therapeutic approaches encounter a critical limitation, as conventional antibiotic treatment is contraindicated due to its propensity to trigger bacterial SOS response and subsequently enhance Stx production, which increases the likelihood of developing HUS in antibiotic-treated patients. The lack of effective, safe therapeutic options has created an urgent need for alternative treatment strategies for STEC infections.

Shiga toxin-producing Escherichia coli (STEC) is one of the major pathogens responsible for severe foodborne infections, and the common serotypes include E. coli O157, O26, O45, O103, O111, O121, and O145. Vaccination has the potential to prevent STEC infections, but no licensed vaccines are available to provide protection against multiple STEC infections.

Article Synopsis
- * The combination of US and ZEO-NE significantly decreased viable E. coli O157:H7 counts, achieving up to an 8.91 log reduction, while also hindering biofilm formation and altering the bacteria's surface properties.
- * This method not only effectively kills bacteria by disrupting cell membranes and generating reactive oxygen species, but also maintains the quality of fresh-cut cucumbers during storage, indicating its potential for improving food
Sublethal injury and recovery of Escherichia coli O157:H7 after dielectric barrier discharge plasma treatment.

Dielectric barrier discharge (DBD) plasma can be used to control food spoilage and food pathogens. However, DBD plasma may induce sublethal injury in microorganisms, constituting a considerable risk to food safety. This research was designed to investigate the sublethal injury and recovery of Escherichia coli O157:H7 after DBD plasma treatment.
