OWNERS are reminded {that a} wormer treating solely tapeworms continues to be obtainable from vets and that broader-spectrum merchandise are usually not essential to deal with this parasite.
The one earlier product obtainable on the open market that contained solely praziquantel was discontinued in 2018 in a “setback” within the battle in opposition to wormer resistance. The drug was then solely to be obtainable together with ivermectin or moxidectin, that are used to deal with small and huge redworm.
However producer BOVA stepped in to supply a praziquantel-only product. This can be a registered product so can solely be bought by vets, and British Equine Veterinary Affiliation president David Rendle advised H&H it’s “very helpful to keep away from utilizing mixed merchandise when they don’t seem to be obligatory”.
H&H has reported at size on the risks posed by rising wormer resistance within the UK and globally, and solely utilizing medication when they’re wanted, as decided by an ongoing testing-led worming programme, is essential in controlling this.
Mr Rendle defined that tapeworms can’t be recognized in faecal worm egg counts; publicity to them is examined by saliva or blood exams, and ranges in these exams are usually not anticipated to drop instantly after therapy.
“It’s my private opinion that we deal with for tapeworms far too often and we fear an excessive amount of about horses which have antibodies to tapeworms,” he advised H&H. “In mature horses with some degree of immunity, the chance of illness related to tapeworm is low and annual therapy is sufficient for almost all; some don’t must be handled in any respect.
“On the request of vets, BOVA has stepped in to supply a straight praziquantel product that’s solely lively in opposition to tapeworms, to beat exactly the issues which were outlined.”
Mr Rendle mentioned the queries of some homeowners over-treating tapeworm “spotlight the complexities of growing de-worming programmes and the worth in growing an annual plan in partnership along with your vet who can have extra instruments of their equipment than can be found over-the-counter”.
“They will even have data of your property and administration – and on livery yards might be able to coordinate plans for the entire yard, which can cut back everyone’s use of de-wormers and assist forestall the event of additional resistance on the property,” he mentioned. “‘Additional’, as a result of there’ll already be purple worm resistance there.”
Claire Shand, director of parasite and testing firm Westgate Labs, advised H&H it is vital homeowners know there’s a praziquantel-only product.
“It was an actual setback for wormer resistance when Equitape was withdrawn from sale in 2018, so improbable that BOVA stepped as much as fill this hole with their vet particular,” she mentioned. “We suggest it often to prospects and advise them on how one can pay money for it. But it surely doesn’t appear so extensively identified about in some circles, in order many come again to say their vet is unaware of the product or is reluctant to prescribe it.
“As with all testing, we have now to make use of it throughout the context of the science, the state of affairs and the chance. [Tapeworm saliva test] EquiSal is superb and the data it has introduced has helped us to revolutionise our method to tapeworm management because it turned obtainable in 2015.”
Westgate recommends six-monthly testing, primarily based on peer-reviewed analysis, and will suggest 12-monthly if outcomes and circumstances recommend that is protected.
“The analysis reveals that fewer than 30% of horses examined want therapy, which permits us to drastically cut back pointless publicity to chemical compounds,” she mentioned. “Conversely, it additionally permits us to deal with these with a excessive burden successfully, for a lot of of whom one remoted tapeworm therapy isn’t ample due to the reinfection price and the very fact the tapewormers goal grownup reasonably than larval phases of the parasite.”
