2. What is Resistance?
It means that microbes have become
immune against the drugs used to
treatisinfections.
What resistance?
This occurs as a result of the use of
antibiotics.

3. The Human Health
We have a situation
deWitAgroAdvies Bangkok 2013
4. History antibiotics
1928 Fleming
1938 Chain and Florey make penicillin useful in
humans
1942 First life saving treatment
1944 D-day; enough penicillin for all soldiers
1946-1960 Wonder drug era; discovery of
tetracycline, chloramphenicol, many others
5. Early sixties: First signs of resistance
Late sixties – early seventies: analogs
Eighties and nineties: Resistance crisis
reduction of agricultural use, restrictive use
in humans
20?? Postantibiotic ??
7. Use of antibiotics outside the hospital
in Europe

13. Emerging Risks
an example
Dissertation Liny Keessen 2013
Man and Pigs:
Sharing the same C. difficile
deWitAgroAdvies Bangkok 2013
14. C. difficile subtype 078
• Found in man and pigs ( 10%)
• No difference in organic production
• Air inside and outside ( up to 20 m.) is
contaminated
• Causes severe diarrhea
deWitAgroAdvies Bangkok 2013
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.

19. Resistance
• More infections
• Higher costs
• Higher mortality
• Higher risks in human health
• Lower Food Safety
• Higer Risks in Labour circumstances
deWitAgroAdvies Bangkok 2013
22. Relation Human Health and
Agriculture
Of the strains ( ESBL Coli)causing urinairy
tract infections in humans in 2009, 13 % was
identical to “chicken” strains. Trend shows
increase of transfer.
deWitAgroAdvies Bangkok 2013
28. Special strain of Methicillin Resistant
Staphylococcus aureus (MRSA) found in pigs
is also found in pig farmers and, less often,
their families
All evidence taken together suggests that
resistance is transfered from agricultural to the
human sector. How much it contributes to total
resistance in human pathogens is unclear.
30. Seagulls 'may be spreading superbugs‘
By Michelle Roberts, Health reporter, BBC
News
Scientists fear migratory birds may be spreading
hard-to-treat infections after discovering seagulls
can carry antibiotic-resistant bacteria.

32. Investigation University Linköping, Sweden
Effect of traveling
• Of 231 persons 4% was carrier of ESBL
bacteries before travel .
• After traveling this had increased to 32%
(nobody had been in hospital)
India 82% Egypt 57%
Thailand 37% Peru 36%
S.Africa 27% Tanzania 24%
35. Strong increase of resistant strains
1994: strains isolated that are resistant
to all drugs available at that time
Cause: (over)use
USA,1951: 580 tons medical use, 110 tons
growth promotor
1978: 6080 tons medical use; 5580 tons
growth promotor
36. Intensive animal
husbandry is believed to be a
major contributor to the increased
environmental burden of AR
deWitAgroAdvies Bangkok 2013
37. Antimicrobial resistance (AMR) is a
growing problem worldwide there is
an urgent need for :
• Reluctant use of antibiotics
• Reserve the better ones for man
• New medicines to treat resistant
infections

49. PRUDENT USE GUIDELINES
Federation of Veterinarians of Europe
1) Animals receiving antibiotics must be under the
care of the prescribing vet
2) Good administration
3) Species and indication approved, susceptible
4) Dosage regimen based on pharmacodynamics
5) Limit broad spectrum and multiple antibiotics
6) Flock/herd treatment only to prevent spreading
50. Different antibiotics for human usage
and for agriculture
Resistance patterns change rapidly
Hence reviews of the exclusively human
list every other year?
52. Eliminate improper incentives to
prescribe Antibiotics.
Good Agricultural Practice:
Cleaning carefully
Constant removal of refuse
Reduce density
Good quality feed
53. Exclusieve relationship
Goal: not to allow the farmer to shop
around for a vet who easily prescibes
antibiotics
What kind of measures are
implementable?
59. A new Animal Health Strategy
for the European Union
(2007-2013) where
“Prevention is better than
cure”
60. Goal 1
To ensure a high level of public
health and food safety by
minimising the incidence of
biological and chemical risks to
humans.
61. Goal 2
To promote animal health by
preventing/reducing the
incidence of animal diseases,
and in this way to support
farming and the rural economy.
deWitAgroAdvies Bangkok 2013
62. Goal 3
To improve economic
growth/cohesion/competitiveness
assuring free circulation of goods
and proportionate animal
movements
.
deWitAgroAdvies Bangkok 2013
63. Goal 4
To promote farming practices
and animal welfare which
prevent animal health related
threats and minimise
environmental impacts in
support of the EU Sustainable
Development Strategy
