Bacteria For the Human Good

Probiotics Microorganisms thought to be healthy to the live host (human)

What can they do? Prevent forms of cancer Lower Blood pressure and cholesterol Prevent Infection Aid in digestion Improve immune system Prevent pathogenic growth Produce medicines Many more…………… http://nccam.nih.gov/health/probiotics/ http://findarticles.com/p/articles/mi_m0FD N/is_2_8/ai_103377069/

Medicine production Insulin (diabetes) used to be taken from cows and pigs. Now the insulin, a protein, gene can be inserted via a plasmid into E. coli The E. coli can produce this protein when activated by the sugar lactose HGH used to be taken from cadavers Now HGH is produced in the same fashion as insulin and can be produced much faster

Insulin Production

Digestion Supports proper digestion The microflora helps break down food into easily absorbed nutrients Produce and degrade vitamins Help the body digest dairy products Break down dietary toxins Maintain the growth of friendly bacteria Strengthen our intestinal defenses and protect our bodies from unwanted invaders like disease-producing organisms Increase resistance to infection Prevent food poisoning bacteria, Salmonella and E-coli from attaching to intestinal cells http://www.nutrition-health- supplements.com/probiotics.html

Disease Prevention The human immune system is very complex and the gut immune system is intense Antibiotic use can kill off good digesting bacteria, in its place bad pathogenic bacteria can grow Probiotics can replenish good bacteria Probiotics and Colon polyps and cancer Probiotics and Irritable Bowel Syndrome Probiotics and Ulcerative Colitis and Crohn's Disease And many more

Antibiotics Substance or compound that kill bacteria or inhibits growth and reproduction Used to treat infections of microorganisms, some protists and fungi Each antibiotic has a method of destruction for its target cell

Antibiotic Targets on a bacteria cell

Antibiotic Resistance The microorganism becomes immune to the specific antibiotic Microorganism evolves (changes) through genetic mutation and transferred through conjugation, transduction and transformation How does this develop?

Future of probiotics Probiotics will become personalized dependant upon the individual DNA and lifestyle May get overused May evolve into something harmful
