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.

Special imports digital service set to change

News Story 1
 From Monday, 15 July, Special Import Certificate (SIC) applications will only be accepted via the Veterinary Medicines Directorate's (VMD's) new special imports digital service.

The original online special import scheme will be decommissioned. The VMD says that the new service is easier to use, more secure and reliable, and meets accessibility legislation.

The VMD is urging veterinary surgeons who have not yet signed up for the new service to do so before 15 July. The new digital service can be accessed here

RCVS course explains concerns process

A free, online course from the RCVS Academy has been launched, designed to clarify RCVS' concerns procedure.

The content will give veterinary surgeons and veterinary nurses a better understanding of the process, and what they can expect if a concern is raised about them. It includes details of common concerns.

The interactive resource has been developed in collaboration with Clare Stringfellow, case manager in the RCVS Professional Conduct Team.

Ms Stringfellow said: "We appreciate that concerns can be very worrying, and we hope that, through this course, we can give vets and nurses a better understanding of the process and how to obtain additional support."

The course can be accessed via the RCVS Academy. Users are encouraged to record their learning for CPD.
