Abstract:
... The objective of this study was to evaluate the mechanism of the synergistic antimicrobial effect of cineole (CN) and carvacrol (CR) on E. coli and its application on fresh-cut cucumbers. Herein, the CN/CR synergy could effectively inhibit E. coli by destroying its bacterial cell structure and causing the leakage of intracellular organic matters. For the first time, CN/CR synergy interaction on E. ...

Since the implementation of STEC screening in Alberta in 2018, it is also essential to have a molecular serotyping method with faster turnaround time for cluster identification and surveillance purposes. This study sought to perform molecular serotyping of the top six non-O157 (O26, O45, O ...

Binding of STx to Gb₃ is a prerequisite for its internalization into the host cells, and the ceramide’s fatty acid of Gb₃ has been shown to influence STx binding. In in vitro studies on liquid ordered (lₒ)/liquid disordered (ld) coexisting artificial membranes, Shiga toxin B (STxB) binds solely to lₒ domains, thus ...
