Don’t forget liver fluke
A northern NSW sheep producer recently had deaths caused by liver fluke and is now madly drenching all his sheep to prevent further losses.
They normally don’t drench for liver fluke on this property because they rarely get confirmed deaths from liver fluke and are not aware it is a cause of ill-thrift.
They could be right of course, and it may not be economic for them to treat for fluke. However, as we know from roundworms, 80% of the losses to the Australian sheep industry from worms is from loss of production, much of which goes unnoticed, unless you deliberately measure productivity, for example, growth rates. The situation is similar with liver fluke: most of the cost is from reduced productivity.
The deaths in this case followed a classic pattern. Rainfall of late had been below average, and the sheep were grazing a lot in gullies and along creeks where the remaining ‘green pick’ was. This is also the place for liver fluke.
This producer has a good vaccination program, so at least black disease, a clostridial disease which can be associated with liver fluke infections, did not become an extra problem.
It would be a good idea for this farmer to test for liver fluke a few times a year. Testing around the usual times to treat for liver fluke – April, August and February – would be a good start, and then review the situation after a couple of years. Drenching all stock this April or May at least – when the cold weather starts – would be a good move too, especially if we get good rain in summer and autumn, which will increase numbers of liver fluke on pasture.
I have suggested that, 3-4 weeks after treating for liver fluke, he gets a fluke worm egg count done, as a rough test of drench efficacy. There are cases of flukicide resistance.

Nodule worm – revised NSW DPI PrimeFact
The revised edition, which includes mention of Dr KM Dash, the ‘father of WormKill’, is now on-line:
Australian survey on farmer parasite management practices
This is not new information, but it is worthwhile revisiting or at least book-marking.
Clunies Ross drench gun
A couple of years ago, Tony Lisle, who was the technical officer for famous Australian parasitologists, Ian Barger, and Hugh McL Gordon before him, showed me the Clunies Ross drench gun (which I photographed). This was just before Tony took it to its new home with parasitologist David Emory at the University of Sydney.
Ian Clunies Ross drench gun. Presented to him on his retirement by Hugh McL Gordon of CSIRO.
Tony tells me that Hugh Gordon, then at CSIRO‘s McMaster Laboratory next to the Sydney Uni vet school, presented this inscribed drench gun to Ian Clunies Ross on his retirement. After Clunies Ross died, his family gave it back to Hugh Gordon for safekeeping. It then passed into the care of various other people in CSIRO, including Leo Le Jambre, and more recently Tony Lisle.
From the Macquarie Dictionary
Clunies–Ross/kluniz-ˈrɒs/ (say kloohneez-‘ros)
noun 1. Sir (William) Ian, 1899–1959, Australian veterinary scientist; involved especially in research.
2. John, Scottish seaman; founded a settlement on the Cocos (Keeling) Islands in 1827, establishing hereditary rule on the islands, which lasted until 1978.
“Ian Clunies-Ross studied veterinary science at the University of Sydney. After postgraduate work in England he returned to the university, where he was professor of veterinary science (1940–46) until his appointment to the executive of the Council for Scientific and Industrial Research (CSIR). Later this reconstituted body became the CSIRO and Clunies-Ross became the first chairman, retaining the position until his death. He was the writer of more than 60 research papers and was honoured by many institutions”.

Understanding your brain can make you calmer, much more productive
Article at Mercola.
Summary: “In closing, Dr. Compernolle’s advice can be summarized into the following “Three Commandments,” plus a very strong fourth recommendation:
- Ruthlessly, radically eradicate multitasking
- Disconnect from electronic media to reflect — to use your thinking brain
- Disconnect to have a break; a break for your reflecting brain to recuperate and for your archiving brain to archive
- Never ever use your phone while driving.
The story at a glance:
Multitasking effectively is neurologically impossible for our thinking brain. The rest of our brain is continuously multitasking. Different parts of your brain have different characteristics, governing reflex, reflective, and archival activities. Your brain cannot multitask in reflective mode
To boost your productivity, batch process your emails, at most four times per day; avoid CC’ing people and avoid “Reply to All”; and understand you do not have to answer all emails
Regularly disconnecting from your electronic communications devices is critical, to give your brain time to recuperate and archive information. Taking time for your brain to “do nothing” can boost your productivity.
“In the lead-up to the release of new Star Wars movie The Force Awakens, we set out to log and map out every scene from every Star Wars movie.Yes, we even watched the prequels.
We were inspired in this endeavour by xkcd’s hand-drawn movie narrative charts, but our mission was to write code that could adequately replace artist Randall Munroe’s illustrations.
The charts below show all the scenes from the first six Star Wars movies, mapping out interactions between the characters. The horizontal axis represents time and vertical groupings are based on how regularly characters interact.
If you’re having trouble understanding them, use the force.”
I like xkcd’s hand-drawn charts (e.g. of ‘Lord of the Rings’) better.
From the opening part of the Star Wars VII movie: “Luke
Ste Skywalker has vanished..” Maybe he is just on leave.
Star Wars and worms
Douglas Adams (“Hitch-hikers Guide to the Galaxy” etc), said the Force was like duct tape: it has a light side and dark side and it holds the universe together.
What about worms? Well in some ways worms can be ‘forces for good’, e.g. in some cases worm infections can modulate the immune system of human hosts to, for example, reduce immune reactivity in the case of allergies, and moderate the immune response in ulcerative colitis, and in coeliac disease.
