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.”

Vets to run marathon for World Animal Protection

News Story 1
 Two recently graduated veterinary surgeons will be running the London Marathon in April to raise money for the charity World Animal Protection.

Alex Bartlett and Maeve O'Neill plan to run the race together if they are given the same start times.

Dr O'Neill said: "You're always limited in what you can do to help animals, so it is nice to raise money for a charity that helps animals around the world."

Dr Bartlett added: "I have never run a marathon before and am excited to run my first one for such a good cause!"

Both Dr Bartlett and Dr O'Neill have fundraising pages online.

BSAVA releases new Guide to Procedures

The British Small Animal Veterinary Association (BSAVA) has published a new edition of its Guide to Procedures for Small Animal Practice.

It has added four new procedures; cystostomy tube placement, endotracheal intubation, point-of-care ultrasound and wet-to-dry dressings.

BSAVA says that it is an essential step-by-step guide to diagnostic and therapeutic procedures performed in practice. The textbook includes new images and illustrations, as well as high-definition videos for use prior to procedures.

Nick Bexfield and Julia Riggs, editors of the new edition, said: "We have built upon the success of the previous editions by responding to the feedback received from the BSAVA readership, and hope this new guide helps to further increase the confidence and accuracy with which these procedures are performed."

Print copies are available in the BSAVA store, with a digital version in the BSAVA library.
