Following is a Merial/Ancare press release on the Haemonchus Dipstick Test.
As mentioned in the release, development of the test was an Australian Sheep Industry CRC project. The test itself was the brain child of CSIRO Armidale scientist and veterinarian, Dr Ian Coldizt
, who lead the scientific team. Others involved were CSIRO Armidale scientist Dr Leo Le Jambre, Dr Gareth Hutchinson, formerly a parasitologist with NSW DPI (now I&I NSW
) at EMAI
, parasitologist Maxine Lyndal-Murphy from Queensland DPI (now ‘DEEDI’
), and veterinarians Deb Maxwell of Armidale, and Rob Woodgate and Brown Besier from Western Australia. The writer played a minor role (I fetched the coffee :-).
Training days for prospective users will be conducted over the coming months. Interested graziers should contact their local Merial or Ancare Territory Manager or their local rural reseller for further information.
There have already been inquiries about use of the test in other host species affected by Haemonchus
, notably goats and also alpaca.
The test has only been evaluated in sheep, so it is not known how well it will work in species other than sheep or how the results should be interpreted. So, at this stage at least, it’s use in other species cannot be recommended.
"THE HAEMONCHUS DIPSTICK TEST KIT
Revolution in early barbers pole worm detection
Graziers will soon have a quick and highly effective tool to detect when sheep should be treated to prevent Barbers Pole worm disease (haemonchosis) outbreaks.
Producers and their advisors can now use the tool in conjunction with the reliable yet time-consuming faecal egg count monitoring, as well as paddock records, grazing management and a degree of intuition to determine which mobs are at risk of, or are affected by, Barbers Pole worm.
The Haemonchus Dipstick Test kit is to be commercially available this spring, coinciding with the time when Haemonchus contortus
can appear in the higher-risk areas of northern NSW and Queensland, and at times in southern higher rainfall zones, including Victoria and south-west WA.
The test also gives results before worm egg counts rise. Immature worms are detected by the test about a week before they produce eggs, which is when they are already causing serious disease in sheep.
The kit has been developed by the Sheep CRC. It will be available to industry through distributors of the range of Merial and Ancare products. Both see the kit as a valuable tool for producers and they are about to embark on farmer and rural store training field days to ensure correct usage of the kit.
Sheep CRC project manager and Principal Veterinary Parasitologist with the Department of Agriculture & Food WA, Dr Brown Besier, found that this worm species can be quickly and easily tested for, on-farm.
“The basis for the test is that Barbers Pole worms are blood-sucking internal parasites, and as they feed in the abomasum, some blood passes through the digestive tract.
“The testing tool is chemically sensitive to haemoglobin (a product of blood breakdown) and changes colour according to the amount of blood in the sample,” he said.
“If there is a significant Barbers Pole Worm burden present, there is more blood in the faeces – seen as a colour change on the dipstick. Assessed in relation to weather conditions and sheep factors, this will indicate to farmers and advisors if, or when, drenching is required.”
The major benefits of the Haemonchus Dipstick Test kit include:
Results are available within 30 minutes on-farm
Worm burdens are detected before egg production begins (before worm egg counts are of any value in diagnosis)
The test is easily accessible and able to be kept on-hand on-farm
The test is reliable, accurate and inexpensive
Director of Large Animal Business with Merial and Ancare, Jack Bree, explains that the kit will be available as an off-the-shelf package with all components and instructions included and enough materials for 50 tests in each kit.
“Farmers will still need to collect dung samples from the paddock, but from there it’s a much easier, quicker and cost-effective process; we find it takes about half an hour from sample collection to test result. The speed and cost of the testing process allows for regular testing of multiple mobs to occur, really allowing for close monitoring of this dangerous parasite.
“The sample is mixed with water, heated in a water bath and then cooled. The test-stick is inserted into the solution and then the colours on the stick change according to the amount of haemoglobin in the faecal sample. Testing is simple and quick, but a very precise process has to be followed to ensure correct readings.
“Through the warmer months it could be used up to once per week to predict risks, while in spring and autumn, temperature and rainfall conditions will determine how often it’s used,” he said.
Chairman of the Sheep CRC, Dr John Keniry, says the Haemonchus Dipstick Test is a prime example of how the CRC model works to develop and deliver scientific solutions to key production problems.
“Few farmers do conventional worm egg counts every week due to the cost, but this means industry runs a risk of stock losses when there are rapid increases in Barbers Pole infection.
“Having identified that a quick-test is both required and possible, the scientists worked to refine the technology and prove its practicality, and the CRC then offered the completed package to specialist agri-businesses to manage the commercialisation process.
“We are very pleased that Merial and Ancare have seen the product’s merits, and have become the commercial partners to make it available to producers.”
“With contributions and funding from the key producer R&D bodies AWI and MLA, and state agencies, universities and key consultants; the Sheep CRC is able to draw on national expertise and resources to address priorities.
“The kit is but one of a range of tools and techniques being delivered and developed by the CRC to help drive productivity and profitability growth in the sheep industry.”

* Merck and SP
"The Australian Competition and Consumer Commission (ACCC) ( this week) announced that it would not oppose the proposed acquisition of Merck by Schering-Plough. The
ACCC also decided to accept a court enforceable undertaking from Merck and Schering-Plough, providing that the merged entity would not take steps to combine the Intervet Schering-Plough and Merial animal health businesses until such time as the ACCC advises that the transaction does not raise competition concerns.
The ACCC concluded that the proposed acquisition of Merck by Schering-Plough did not raise competition concerns in relation to any human health market".
* RSS and Change Detection
RSS – Really Simple Syndication – is a nice way of keeping up with information you want to keep up with. (Unless you like to spend all of your day surfing the web, in between Twittering and Facebooking).
For more information: http://en.wikipedia.org/wiki/RSS
If a webpage you are interested in is RSS-enabled (you will see the tell-tale logo), then you can have updates delivered to your RSS reader. There are various ways of reading your RSS feeds, for example, in Apple Mail, or Mozilla Thunderbird, or in web browsers eg FireFox, or in Google Reader, if you have a Google/Gmail account.
Useful sites such as WordPress (and Tumblr, Blogger, Twitter etc), Dilbert and ABC News provide RSS feeds, but others, such as WormBoss and Industry and Investment-Primary Industries either have no or limited RSS feeds.
But, for these sites, you might consider something like Change Detection. http://www.changedetection.com/
WormBoss however partly gets around the problem of no RSS feeds by providing a monthly update by email. Subscribe to this at the WormBoss site.
I&I NSW, under the leadership of Alex Russell, is working a new ‘clearing house’ for sheep-related information. But my lips are sealed.
