Now we jump back up to the
FAMILY of Enterobacteriaceae.
All Enterobacteriaceae live in the intestinal tracts of animals, including humans. E. coli of course is in the Escherichia Genus (in bold)

Why we wash our hands!!!!!!
This is why we test water for e.coli concentrations in drinking water and at swimming lakes and rivers.
Negative E.coli strains have injured and killed people through spinach, tomato and hamburger consumption.

How can antibodies help with detection of Bacteria & Viruses?
• Antibodies are protein molecules, usually developed by the immune system in mammals.
• The immune system uses the antibodies to identify and neutralize bacteria and viruses.
• For every bacteria or virus there is an antibody to identify & neutralize that bacteria or virus.
Slide 20
What if………
• We use the antibody to find the bacteria or virus……….
BUT…
•
How will we know that the antibody found the bacteria/virus????

Slide 34
Current dilemmas & challenges?
• How do we get industry interested in manufacturing biosensors?
• Should biosensors be legislated as mandatory at food processing plants? How could this save or cost industry in dollars?
• Or should biosensors be left to personal use for an individual to have on hand an home?
• Others?
