  • Hsu, Yu-Hung (Lethbridge, Alta. : University of Lethbridge, Dept. of Biological Sciences, c2011Arts and ScienceDepartment of Biological Sciences, 2011)
    Mannheimia haemolytica is the principal bacterial agent associated with bovine respiratory disease (BRD). It has a significant economic impact on the beef feedlot industry. The current methods for BRD prevention and treatment ...
  • Lussier, Pamela; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Biological Science, 2010Arts and ScienceDepartment of Biological Science, 2010)
    This thesis describes the detection, and characterization of putative extended-spectrum β-lactamases (ESBLs) producing Escherichia coli isolated from feedlot cattle in southern Alberta. Cattle either received no antimicrobials ...
  • Klima, Cassidy L.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Biological Sciences, c2009Arts and ScienceDepartment of Biological Sciences, 2009)
    Mannheimia haemolytica is an opportunistic pathogen in cattle and the main bacterial agent in bovine respiratory disease. Despite its economic importance, few studies have characterized the genetic diversity of M. haemolytica, ...
  • Strauss, Colin Earl; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2000Arts and ScienceDepartment of Chemistry and Biochemistry, 2000)
    The yeast expression system Pichia pastoris was investigated as an encapsulation technology capable of serving as a rumen escape vehicle. Cellularly encapsulated protein is protected from the ruminal environment so long ...
  • Lowe, Ross M.S.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Biological Sciences, c2009Arts and ScienceDepartment of Biological Sciences, 2009)
    Escherichia coli O157:H7 is an important human pathogen that resides primarily in cattle and feedlot environments. E. coli O157:H7 can be divided into phylogenetic groups termed lineages; lineage I strains are responsible ...
  • Puhl, Aaron A.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2006Faculty of Arts and ScienceDepartment of Biological Sciences, 2006)
    A novel bacterial protein tyrosine phosphatase (PTP)-like enzyme has recently been isolated that has a PTP-like active site and fold and the ability to dephosphorylate myo-inositol hexakisphosphate. In order to expand our ...
  • Geddes, Jennifer M H; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2006Arts and ScienceDepartment of Biological Studies, 2006)
    An evaluation of nineteen barley lines using three artificial inoculation methods concluded that spray inoculation was the most reproducible method and provided the greatest discrimination of resistance. Six of the nineteen ...
  • Lang, Cassandra C.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2005Arts and ScienceDepartment of Biological Sciences, 2005)
    Metabolic were used to evaluate Enterococcus as an indicator of faecal pollution. Enterococci were isolated using m-Enterococcus agar and speciated using conventional biochemical tests. Forty percent of the isolates were ...
  • Kalischuk-Tymensen, Lisa; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2001Arts and ScienceDepartment of Biological Sciences, 2001)
    There is a discrepancy in the current literature concerning the stage of development in which horn flies arrest during pupal diapause. A study was therefore conducted to describe the morphologies of horn fly pupae and its ...
  • Rochon, Kateryn; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2003Arts and ScienceDepartment of Biological Sciences, 2003)
    The persistance of Escherichia coli in the larval, pupal and adult stages of both house flies, Musca domestica (L.), and stable flies, Stomoxys calcitrans (L). was examined. Abundance of E.coli declined over time in immature ...
  • Gruninger, Robert J; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Chemistry and Biochemistry, c2009Arts and ScienceDepartment of Chemistry and Biochemistry, 2009)
    The structure and mechanism of the Protein Tyrosine Phosphatase-like Phytases (PTPLPs) from Selenomonas ruminantium (PhyAsr) and Mitsuokella multacida (PhyAmm) were investigated using a combination of enzyme kinetics, ...
  • Penniket, Carolyn Renee (Lethbridge, Alta. : University of Lethbridge, Dept. of Biological Sciences, c2013Arts and ScienceDepartment of Biological Sciences, 2013)
    Triticale (x Triticosecale Whitm.) is a cereal with favorable agronomic traits for a Canadian bioproduction platform crop. Appropriate tissue sampling times were determined and gene expression profiles were evaluated in ...
  • Stevenson, Sam M. L.; University of Lethbridge. Faculty of Arts and Science (Lethbridge : University of Lethbridge, Facutly of Arts and Science, 2002Arts and ScienceDepartment of Biological Sciences, 2002)
    Transfer and shedding of a rifampicin-resistant strain of Escherichia coli (RREC) among cattle was studied in a research feedlot comprised of 30 pens of 11 or 12 yearling steers. On 3 separate occasions, 9,6 and 6 of the ...
