    The 16S/23S ribosomal RNA (rRNA) intergenic space (IGS) regions from pathogenic and non-pathogenic species (spp.) of Listeria were characterized by the polymerase chain reaction (PCR) and DNA sequencing. DNA sequencing ...
  • Kruczkiewicz, Peter (Lethbridge, Alta. : University of Lethbridge, Dept. of Biological Sciences, c2013Arts and ScienceDepartment of Biological Sciences, 2013)
    Although increased genome sequencing e orts have increased our understanding of genomic variability within many bacterial species, there has been limited application of this knowledge towards assessing current molecular ...
  • Paquette, Sarah-Jo (Lethbridge, Alta. : University of Lethbridge, Dept. of Biological Sciences, c2011Arts and ScienceDepartment of Biological Sciences, 2011)
    Escherichia coli O157:H7 is an enteric pathogen that can cause severe gastrointestinal disease, sometimes leading to hospitalization and death. These bacteria have a variety of virulence factors that can be encoded for on ...
  • Attram, Jeremiah (Lethbridge, Alta. : University of Lethbridge, Dept. of Biological SciencesArts and ScienceDepartment of Biological Science, 2014)
    Field studies were conducted at Lethbridge and Picture Butte in 2012 and 2013 to determine the effects of irrigation water application levels on the dry matter yield, water use efficiency (WUE) and forage quality of irrigated ...
  • Ross, Susan; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Biological Sciences, c2010Arts and ScienceDepartment of Biological Sciences, 2010)
    This thesis reports the development of Comparative Genomic Fingerprinting (CGF), a rapid genotyping method for Campylobacter jejuni that assesses the conservation status of 20 genes previously described as having high ...
  • Groft, Donald G.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 1997Arts and ScienceDepartment of Biological Sciences, 1997)
    Bull trout (Salvelinus confluentus) populations from Alberta river drainage systems were compared using molecular techniques. Restriction fragment length polymorphisms (RFLP's) within the NDI and ND5/6 regions of the ...
  • Laing, Chad; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Biological SciencesArts and ScienceDepartment of Biological Sciences, 2013)
    Human infections with Shiga-toxin (Stx)-producing E. coli (STEC) vary in severity of illness. The pan-genome of a bacterial species contains a shared, essential core genome, and a variably distributed accessory genome. ...
  • Hallewell, Jennyka; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Biological Sciences, 2014Arts and ScienceDepartment of Biological Sciences, 2014)
    Cattle are reservoirs of E. coli O157:H7 and contamination of carcasses during slaughter transfer this potentially deadly pathogen into the human food chain. The goal of this study was to assess: 1) the effect of feeding ...
