“Blown-pack” spoilage of beef by psychrotrophic Clostridium spp. occurs sporadically and resistance of the endospores to most interventions makes them very difficult to control. Current interventions used to control spoilage and pathogenic bacteria, such as acid washes and heat treatments, do...

Application of antimicrobials for the elimination of Escherichia coli and Listeria monocytogenes in brine injected beef
DownloadFall 2013
The application of antimicrobials to a brine-injected raw beef roast for the elimination/inhibition of heat resistant Escherichia coli and Listeria monocytogenes was investigated. The choice of antimicrobials for use in brine injected beef was based on minimum bactericidal concentration in brine...

Although nanocrystalline silver is used commercially to treat burns and wounds, the mechanisms of action (MOA) for its activity are not clear. The purposes of this work were to determine if nanocrystalline silver has anti-inflammatory activity, determine physicochemical properties critical for...

Effect of Antimicrobial Exposure on Clostridioides difficile (C. difficile) Colonization of the Infant Gut Microbiota in the Canadian Healthy Infant Longitudinal Development (CHILD) Birth Cohort
DownloadSpring 2020
Introduction: Antimicrobial exposure in early life has been associated with gut microbiota dysbiosis and development of allergic diseases in childhood. In adults and older children, C. difficile is the major pathogen responsible for antibiotic-induced diarrhea but the effect of colonization with...

Effects of production system and growth promotants on the physiological maturity scores in steers
Download2014
Aalhus, J. L., Basarab, J. A., N. Prieto, I. L., López-Campos, Ó., Larsen, M.
Over a 2-yr period, 224 crossbred steers were allotted to a 2×2×2 factorial arrangement of treatments to determine the effect of the production system (calf-fed vs. yearling-fed), growth implant strategy (non-implanted vs. implanted) and β-agonist supplementation (no ractopamine vs. ractopamine)...

Modification of beef quality through steer age at slaughter, breed cross and growth promotants
Download2012
Aalhus, J. L., Basarab, J. A., Girard, I., Bruce., H. L., Larsen, I. L.
A 23 factorial experiment tested the interactions of slaughter age (12–13 or 18–20 mo), growth implants use (Component E-S, TE-S), ractopamine hydrochloride (RAC) feed supplementation use and breed cross [Hereford–Aberdeen Angus (HAA) or Charolais–Red Angus (CRA)] on pH, temperature, objective...

Bruce., H. L., Aalhus, J. L., Larsen, I. L., Girard, I., Basarab, J. A.
A 24 factorial experiment tested the interactions of slaughter age (12–13 or 18–20 mo), growth hormone use, β-adrenergic agonist (β-AA) use and breed cross [Hereford–Aberdeen Angus (HAA) or Charolais–Red Angus (CRA)] on the composition, fibre types, and connective tissue characteristics of m....

Mussels can obtain strong underwater attachment to virtually all kinds of surfaces including rocks, metals, wood structures, polymers and concretes by secreting mussel foot proteins to form byssus. Great efforts have been dedicated to understanding this behavior and it is found that an catecholic...
