    • Jim ThomasAgricultural BiotechnologyUniversity of Lethbridge
    • 1. Identification of traits specific to a pathogen or contaminate : allows use of specific antibodies or enzyme reactions to identify a contaminate
    • 2. Use of selective media for growth of bacterial pathogens: inclusion of Cefixime (cephalosporin antibiotic) in Sorbitol-MacConkey growth medium for bacteria allows selection for growth of E. coli O157:H7
    • 3. Molecular characterization: allows use of unique gene sequences (e.g., toxin genes) to identify some bacteria and viruses
    • Epidemiology: find the source of the problem
    • Much of our food is processed through central facilities • recalls are costly
    • • For most bacterial pathogens need 10, 000 to 100,000 to infect
    • • E. coli O157:H7 is a Shiga toxin- producing E. coli that was 1st identified in a human with bloody diarrhea in 1975• identified as a food-borne pathogen in 1982• only takes 1 to 10 to infect
    • • cutbacks in personnel• cutbacks in money• access to organisms• access to information• negative lobby• how will the information be used (bioterrorism)
