Testing guidance reissued after wormer resistance reports
“The best approach to prevent wormer resistance is to evaluate and implement improved pasture management” – Prof Jacqui Matthews.
Treatment failure reported for praziquantel and pyrantel.

Following reports that equine tapeworm drugs may be losing efficacy, Austin Davis Biologics (ABD) has reissued its guidance on the use of EQuiSal salvia testing for informing tapeworm control.

A recently published study from the Department of Veterinary Science at the University of Kentucky found evidence of treatment failure of praziquantel and pyrantel, the only two drugs licensed in the UK for tapeworm control in horses.

Responding to this development, ABD is emphasising that owners should not repeatedly test and treat for tapeworm without evaluating management, as this could lead to resistance.

Professor Jacqui Matthews, director of veterinary science at ADB, said: “In horses that report with a borderline or moderate/high saliva score, their management should be evaluated to determine what improvements could be made to help prevent tapeworm reinfection from the pasture.

“As part of this evaluation, a follow up test can be performed three months after treatment to provide information on whether or not reinfection is occurring.”

In cases when horses test positive in the follow up test, Prof Matthews said: “Improvements in pasture management should be undertaken, and/or a tapeworm treatment considered where appropriate, to prevent further grazing contamination with tapeworm eggs.

“All co-grazing horses should be tested at the same time in case they act as a continued source of tapeworm eggs. The best approach to prevent wormer resistance is to evaluate and implement improved pasture management to move to a situation where recurring reinfection is considerably reduced.”

ABD suggests that when saliva scores stay high despite taking the suggested measures, anthelmintic resistance should be considered a possibility. In such cases, the company recommends that owners seek advice from their veterinary surgeon.

Bristol uni celebrates 75 years of teaching vets

News Story 1
 The University of Bristol's veterinary school is celebrating 75 years of educating veterinary students.

Since the first group of students were admitted in October 1949, the school has seen more than 5,000 veterinary students graduate.

Professor Jeremy Tavare, pro vice-chancellor and executive dean for the Faculty of Health and Life Sciences, said: "I'm delighted to be celebrating Bristol Veterinary School's 75 years.

"Its excellence in teaching and research has resulted in greater understanding and some real-world changes benefiting the health and welfare of both animals and humans, which is testament to the school's remarkable staff, students and graduates."

RCVS HQ to temporarily relocate

The headquarters of the Royal College of Veterinary Surgeons (RCVS) is to move temporarily, ahead of its permanent relocation later in the year.

From Monday, 26 February 2024, RCVS' temporary headquarters will be at 2 Waterhouse Square, Holborn, London. This is within walking distance of its current rented offices at The Cursitor, Chancery Lane.

RCVS have been based at The Cursitor since February 2022, following the sale of its Westminster premises the previous March.

However, unforeseen circumstances relating to workspace rental company WeWork filing for bankruptcy means The Cursitor will no longer operate as a WeWork space. The new temporary location is still owned by WeWork.

RCVS anticipates that it will move into its permanent location at Hardwick Street, Clerkenwell, later on in the year.
