Waarom maken we ons druk over AB resistentie?
Eten van vlees veroorzaakt antibioticaresistentie!!!!(Door: Wans Horst)Resistentie tegen antibiotica kan verschrikkelijke gevolgen hebben voor de wereldwijde bevolking. Daarom moet de resistentie bij de wortel worden aangepakt en niet bij de oplossing, zoals de Wereldgezondheidsorganisatie wil.

Wat is een volksgezondheid risico ikv gebruik AB bij dieren?
1.Er ontstaan AB resistente bacterien in het dier en die komen
daarna op vlees/in millieu.
2.Er komen residuen van AB in het vlees
1 of 2, of beide of beide niet?
![Page 7: Institute for Risk Assessment Sciences Veterinary Public Health Biosecurity en AB resistentie Len Lipman IRAS/VPH Faculteit diergeneeskunde 4 oktober 2015.](https://reader036.fdocuments.in/reader036/viewer/2022081421/5697bf8d1a28abf838c8c2bd/html5/thumbnails/7.jpg)

In de bestrijding van ABR moeten we?
1. Dus minder AB gebruiken!!!
2. En slachtdieren niet in contact laten komen met
AB resistente bacteriën.
1, 2, beide of beide niet?
En is er een Relatie met biosecurity?

Introduction
– Aim: determine whether flies, wild birds, mice and rats may carry antibiotic resistant bacteria in the animal husbandry in the Netherlands.
– MRSA and ESBL/AmpC producing E.coli, Enterobacter spp and Klebsiella spp.

Discussion: MRSA
– MRSA was isolated from a black rat
– In line with results of Van de Giessen et al. 2009 From five out of 40 black rats MRSA was isolated
![Page 22: Institute for Risk Assessment Sciences Veterinary Public Health Biosecurity en AB resistentie Len Lipman IRAS/VPH Faculteit diergeneeskunde 4 oktober 2015.](https://reader036.fdocuments.in/reader036/viewer/2022081421/5697bf8d1a28abf838c8c2bd/html5/thumbnails/22.jpg)
Results: ESBL/AmpC producing E.coli Enterobakter
– ESBL producing E. coli isolated from a brown rat
– AmpC producing Enterobacter spp. isolated from two fly pools
– AmpC producing Enterobacter spp. isolated from a brown rat

Conclusion research
–Vermin may carry MRSA and ESBL/AmpC producing E. coli and Enterobacter spp. in the Dutch animal husbandry
–Biosecurity!!!!!
–Small number of samples investigated
