Understanding host-microbiome interactions and influence on STEC colonization in cattle using integrated omics
DownloadFall 2023
Shiga toxin producing Escherichia coli (STEC) is the major foodborne pathogen in humans with Shiga toxin 1 (stx1) and 2 (stx2) being the main virulence factors. Cattle are the major reservoir of STEC with those shedding >104 CFU/g STEC being defined as super shedders (SS). The rectal anal...

Characterization of Heat Resistant Escherichia coli Isolates Associated with Human Infection
DownloadSpring 2021
Shiga toxin-producing Escherichia coli (STEC) is a bacterial pathogen associated with foodborne diarrheal disease. Infection with STEC presents as a mild, watery diarrhea to hemorrhagic colitis and can progress to the life-threatening complication, hemolytic uremic syndrome. Cattle are recognized...

Approximately 70% of the cost of beef production is impacted by dietary intake. Maximizing production efficiency of beef cattle requires not only genetic selection to maximize feed efficiency (i.e. residual feed intake - RFI), but also adequate nutrition throughout all stages of growth and...

Effect of breed type and residual feed intake on meat and collagen quality and expression of genes involved in collagen synthesis and degradation in bovine m. gluteus medius
DownloadSpring 2020
Residual feed intake (RFI) is an index of feed efficiency that has been demonstrated to be moderately heritable, with cattle having low RFI values being efficient as they consume less feed for the same weight gain. This may be of financial benefit to producers, but to be fully beneficial to...

Detection of enterohaemorrhagic Escherichia coli in food by droplet digital PCR to detect simultaneous virulence factors in a single genome
Download2020-09-01
He, Li, Simpson, David, Gänzle, Michael G.
Shiga toxin producing E. coli are a problem for food producers. STEC's require a combination of virulence factors to cause disease, so ideally detection techniques should detect the presence of multiple virulence factors in a single cell directly from food. Droplet Digital PCR (ddPCR) is commonly...

Parkins, John, Goddard, Ellen, Plastow, Graham, Carlyle, Cameron
NFRF-Exploration grant awarded 2020: Sustainability of the beef industry and sustainability of temperate grasslands are equally challenging currently. Beef cattle don’t typically graze on tidy fields of managed pasture, but instead graze complex landscapes with highly diverse vegetation and plant...

Effect of sodium chloride and chitosan on the inactivation of heat resistant or Shiga-toxin producing Escherichia coli during grilling of burger patties
Download2019-01-01
Hu, Ziyi, Rohde, Alina, McMullen, Lynn, Gänzle, Michael G.
Cattle are a reservoir for enterohemorrhagic Escherichia coli (EHEC), and ground beef is a major vehicle for human infection with EHEC. Heat resistance of E. coli, including EHEC, is impacted by NaCl and other additives. This study aimed to evaluate the effect of NaCl and other additives on the...

Performance and Methane Emissions of RFI Selected Cattle in Drylot and Under Open Range Conditions
DownloadSpring 2018
Residual feed intake (RFI) is a moderately heritable trait that can be used to measure feed efficiency in beef cattle, and thereby reduce feed related costs. RFI has been primarily evaluated under drylot conditions where diet, feed intake and activity levels are controlled and foraging behaviour...

Effect of chitosan, and bacteriocin – Producing Carnobacterium maltaromaticum on survival of Escherichia coli and Salmonella Typhimurium on beef
Download2018-01-01
Hu, Zi Yi, Balay, Danielle, Hu, Ying, McMullen, Lynn M., Gänzle, Michael G.
The aim of this study was to investigate the synergistic effect of chitosan and bacteriocins against Escherichia coli and Salmonella in media and in lean beef. The inhibitory effects of chitosan and bacteriocins against E. coli AW1.7 and S. enterica Typhimurium in media were determined by a...

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...
