Comparative assessment of qPCR enumeration methods that discriminate between live and dead Escherichia coli O157:H7 on beef
Download2018-01-01
Laidlaw, Anna M., Gänzle, Michael G., Yang, Xianqin
Quantitative Polymerase Chain Reaction (qPCR) is a molecular method commonly used to detect and quantify bacterial DNA on food but is limited by its inability to distinguish between live and dead cell DNA. To overcome this obstacle, propidium monoazide (PMA) alone or with deoxycholate (DC) was...

Resistance of biofilm- and pellicle-embedded strains of Escherichia coli encoding the transmissible locus of stress tolerance (tLST) to oxidative sanitation chemicals
Download2021-12-02
Xu, Zhaohui S., Yang, Xianqin, Gänzle, Michael G.
Biofilm formation in food processing plants reduces the efficacy of sanitation. The presence of transmissible locus of stress tolerance (tLST) also enhances resistance of planktonic cells of Escherichia coli to sanitation chemicals but the role of tLST in resistance of biofilm-embedded cells...

The locus of heat resistance (LHR) mediates heat resistance in Salmonella enterica, Escherichia coli and Enterobacter cloacae
Download2017-06-01
Mercer, Ryan G., Walker, Brian D., Yang, Xianqin, McMullen, Lynn M., Gänzle, Michael G.
Enterobacteriaceae comprise food spoilage organisms as well as food-borne pathogens including Escherichia coli. Heat resistance in E. coli was attributed to a genomic island called the locus of heat resistance (LHR). This genomic island is also present in several other genera of...
