Sheep drenches, resistance and worm control initiatives – Australia

A colleague asked me some questions about what happened when (when resistance to this or that occurred etc), which prompted me to produce this WormMail.

Here is a timeline from this NSW DPI Primefact: http://www.dpi.nsw.gov.au/__data/assets/pdf_file/0009/111060/Drench-resistance-and-sheep-worm-control.pdf (Relevant pages attached as a PDF).

You may see versions of this material produced by drench companies.

In most cases the time that resistance was reported relates to when the first paper was published in a journal.

In the case of closantel resistance however, the first field case in sheep was found ~ 1987/1988, by then Warialda District Vet Phil Kemsley, during regular WormTesting as part of the WormKill sentinel flock monitoring program. As it happened, the first Australian report of moxidectin resistance in sheep relates to the same farm in northern NSW.

The paper describing the closantel resistant isolate of Haemonchus from the Warialda district was published by Rolfe and others in 1990. (Aust Vet J. 1990 Jan;67(1):29-31. Closantel resistance in Haemonchus contortus from sheep.Rolfe PF, Boray JC, Fitzgibbon C, Parsons G, Kemsley P, Sangster N).

I have updated this timeline recently…. (but its location currently eludes me).

For example, speaking of recent/significant happenings, have I told you that the revamped WormBoss was launched on 21.11.12? If so, do you regularly visit WormBoss? đŸ™‚
