  • 1. NATURE STRIKES BACK A Global Problem Bangkok March 2013 CEO Summit Animal Health deWitAgroAdvies Bangkok 2013
  • 2. What is Resistance?It means that microbes have becomeimmune against the drugs used totreatisinfections. What resistance?This occurs as a result of the use ofantibiotics. deWitAgroAdvies Bangkok 2013
  • 3. The Human Health We have a situation deWitAgroAdvies Bangkok 2013
  • 4. History antibiotics1928 Fleming1938 Chain and Florey make penicillin useful inhumans1942 First life saving treatment1944 D-day; enough penicillin for all soldiers1946-1960 Wonder drug era; discovery oftetracycline, chloramphenicol, many others
  • 5. Early sixties: First signs of resistanceLate sixties – early seventies: analogsEighties and nineties: Resistance crisisreduction of agricultural use, restrictive usein humans20?? Postantibiotic ??

  • 15. Some figures• Antibiotic-resistant bacteria cause 25 000 deaths in EU every year and cost economy €1.5 billion. (IMI/EFPIA project)• If no action is taken to address these issues, we risk leaving society in a situation where doctors will have few, if any, options to treat bacterial infections. deWitAgroAdvies Bangkok 2013
  • 16. • Oct. 16, 2007 -- It appears that more people in the U.S. now die from the mostly hospital- acquired staph infection MRSA than from AIDS, according to a new report from the CDC.• Methicillin-resistant Staphylococcus aureus (MRSA) was responsible for an estimated 94,000 life-threatening infections and 18,650 deaths in 2005, CDC researchers report in the Oct. 17 issue of The Journal of the American Medical Association. deWitAgroAdvies Bangkok 2013

  • 28. Special strain of Methicillin ResistantStaphylococcus aureus (MRSA) found in pigsis also found in pig farmers and, less often,their familiesAll evidence taken together suggests thatresistance is transfered from agricultural to thehuman sector. How much it contributes to totalresistance in human pathogens is unclear.
