Findings from sheep study could help reduce spread of vCJD in humans
The study of sheep was used to estimate the spread of vCJD in humans.

Improved measures may lessen risk of transmission through blood transfer.

A study led by the Roslin Institute has revealed that the risk of spreading variant Creutzfeldt-Jakob disease (vCJD) by blood transfer may be higher than previously thought and that further improvements to preventative measures are needed to reduce the risk of disease spread.

The 12-year study, published in the journal PLOS Pathogens, was funded by the UK’s Department of Health and Social Care. The research looked at the behaviour of vCJD in sheep, in order to estimate the spread of the disease in humans.

Scientists used sheep infected with bovine spongiform encephalopathy (BSE) by oral transmission to investigate whether and how these animals would spread disease to others through blood transfer.

The research revealed that removing white blood cells from red cells, plasma and platelets substantially reduced the risk of spread of vCJD, but did not completely prevent it.

A high number of sheep also became infected after receiving blood with detectable levels of contamination, indicating a high risk of disease spread by blood transfusion.

“If our results reflect the situation in human vCJD, then blood transfusions could contribute to spread of disease as much, or more, as eating contaminated meat,” says researcher Dr Fiona Houston.

The study authors argue that this fatal condition could be tackled more effectively by further improving protective measures, as well as further developing tests to diagnose infection in people.

Dr Khalid Salamat, research fellow at Roslin Institute and co-author of the study, said: “Current control measures appear to be effective, but risks could be further reduced by enhanced methods to remove infectious components from blood products. It is also important to develop ultrasensitive tests that can detect disease in asymptomatic blood donors.”

Applications open for pets in housing research funding scheme

News Story 1
 The Society for Companion Animal Studies (SCAS) has announced that applications are now open for the second round of its three-year funding scheme to support research into the human-animal bond.

This year SCAS is looking for research that focuses on the issues surrounding pets in housing, particularly projects looking at:

- the impact of current, or historic, pet related housing legislation
- an assessment of incident, type and cost of damage caused by pets in housing
- the views of landlords, care institution or housing association staff, in relation to pets and housing
- stakeholder perceptions of pets and housing insurance schemes.

There are eight funding grants available, awarding between £1,500 and £10,000. Applications close on 30 April 2021.

More information can be found on the SCAS website.

2021 NOAH Compendium now available

The 2021 edition of the NOAH Compendium of Data Sheets for Animal Medicines has been published.

Published annually by NOAH, this book is sent to every veterinary practice in the UK for free. The 2021 edition includes an even larger range of products than previous years.

Chief executive Dawn Howard stated that NOAH will shortly be launching a survey for practices on the Compendiums effectiveness.

She added: "Our survey will give users of the Compendium the opportunity to say how they think we can improve it to assist them in prescribing veterinary medicines and advising animal keepers on their use. We look forward to getting your views."
