Event Description
- Full Description:
- Globally, there is much conjecture concerning antimicrobial usage in animals and its impact on public health. Of most concern is the use of extended spectrum cephalosporins (ESC) and fluoroquinolones (FQ) in livestock and the potential risk of transmission to humans through the food chain and/or the environment. Australia is geographically isolated, has restrictions on importation of live animals and some foods and strong regulation governing the use of critically important antimicrobials. The prevalence of multi-resistant organisms in animals appears low in Australia relative to the rest of the world. However, multi-resistant pathogens and commensal organisms, including organisms resistant to ESC and FQ have recently been detected in Australian food producing animals.
This seminar will give an overview of the development of antimicrobial resistance (AMR) in Australian food producing animals and describe some of my recent studies. Respiratory disease is a significant problem causing economic losses in the pig and feedlot industries worldwide. Antimicrobial agents are used to treat respiratory disease caused by bacteria and local current knowledge on AMR is required to ensure successful therapy. Resistance to older and newer antimicrobials were detected. E. coli causes significant disease in the swine industry and we can report moderate to high levels of resistance to commonly used antibiotics in addition to ESC (n=3) and FQ (n=1) in an Australian wide study examining 324 clinical E.coli isolates from food producing animals. Examining commensal E.coli in pigs showed the resistance prevalence varied greatly between farms and that use of registered antimicrobials in Australian pigs leads to the enteric commensal populations acquiring associated antimicrobial resistance genes. In addition to commercial enterprises, backyard industries are becoming popular and preliminary results investigating antimicrobial resistance in E.coli, Salmonella, and Campylobacter in backyard chickens in South East Queensland will be presented.
