Ireland study to explore immunology of bovine TB
An estimated 30-40 per cent of TB-infected herds in Ireland experience a repeated breakdown within three years.
The project will focus on the role of nutrition and Vitamin D in disease recurrence.

Researchers across Ireland have joined forces in a first-of-its-kind study to better understand the immunology of bovine TB.

Scientists from The Institute for Global Food Security (IGFS), the Agri-Food and Biosciences Institute (AFBI) and University College Dublin (UCD) will explore how nutrition and Vitamin D might influence animals' immune response and disease outcomes on farms that experience recurring infection.

Project lead Dr Kieran Meade, from the UCD School of Agriculture and Food Science, said: “Multiple studies now point to an animal-specific issue that prevents current diagnostic tests from identifying all truly infected cattle, and these cattle act as a reservoir of persistent infection.

"The weight of evidence from the human literature and our exciting preliminary data suggests that Vitamin D status will have a decisive impact on livestock immunity to diseases including TB.”

Owing to a relapse of infection on farms on both sides of the Irish border, it is thought that TB-infected herds have a 30–40 per cent probability of experiencing a repeated breakdown within three years. Experts say that to eradicate bTB, the UK, Ireland, and the EU must intensify focus on the causes of recurrent infection.

Professor Ilias Kyriazakis of IGFS, who has a background in veterinary medicine, said: “Queen’s has previously associated Vitamin D status of livestock with their immune response to a variety of pathogens, and this exciting collaboration offers us the opportunity to build on our previous research.”

The researchers aim to identify the host factors contributing to the relapse of infections in specific cattle or herds, and use this knowledge to inform strategies for TB eradication, both in NI and ROI.

Animal Medicines Amnesty returns this November

News Story 1
 Veterinary practices are being urged to help owners safely dispose of any unused and expired pet medicines - not just antibiotics - during November's Animal Medicines Amnesty.

Organised by the Responsible Use of Medicines Alliance Companion Animal and Equine (RUMA CA&E), the initative is supported by a range of cross-sector organisations.

Practices are encouraged to use the campaign to engage the whole practice team and raise awareness of the safe disposal of medicines with clients. Learn how your practice can get involved at rumacae.org.uk

Bluetongue RZ extended across Scotland

The Scottish Government has announced an extension to a Bluetongue Restricted Zone that is in place in south-west Scotland.

From 3 October, the Restricted Zone will be extended to cover the whole of Scotland. The Animal, Plant and Health Agency (APHA) says this is in response to further disease spread, as well as simplify trading conditions ahead of the autumn.

Since the whole country will share a disease status, it will no longer be necessary to have a movement license to move susceptible livestock around the country. Restrictions on germinal products remain.

As of 1 October 2026, there were 1,979 cases of BTV-3 in England, 389 cases in Wales and 40 cases in Scotland.
