DNA discovery could help treat Marek's disease
Scientists identified regions of chicken DNA that are seen to play a role in disease resistance.
Scientists identify genetic regions in chickens associated with resistance.

Researchers at the University of Edinburgh's Roslin Institute have identified regions of chicken DNA associated with resistance to Marek's disease.

Scientists say the discovery, reported in the journal Genes, could pave the way to new therapies or techniques to manage the condition, which costs the global poultry industry some US$ 2 billion every year.The findings also reveal details behind susceptibility to the virus, which could lead to more precise selective breeding strategies.

“Marek’s disease is devastating to flocks worldwide as well as the economy, and current vaccination can only partially control it,” explains Dr Jaqueline Smith, study lead at the Roslin Institute.“Our study identifies regions of the genome associated with resistance, which could be used for mitigating the effects of the virus through selective breeding, improved vaccine design, or future gene-editing technologies.”

In the study, scientists identified regions of chicken DNA that are seen to play a role in disease resistance. Their approach included comparing the DNA of two groups of commercial egg-laying chickens which differed in their resistance to Marek’s disease virus.

The team analysed genetic information from infected chicks and identified variations associated with resistance in the DNA of multiple commercial chicken lines. They also investigated the genetic association with mortality in the infected offspring of egg-laying birds.

Outcomes from this research are the first to provide such a large-scale, high-resolution analysis of genes underlying resistance to the virus in birds relevant to the poultry industry.

Because the tumours caused by Marek’s disease virus have similarities to human lymphoma, researchers hope that their findings may also be able to increase understanding of human cancers.

Birmingham Dogs Home makes urgent appeal

News Story 1
 Birmingham Dogs Home has issued an urgent winter appeal as it faces more challenges over the Christmas period.

The rescue centre has seen a dramatic increase in dogs coming into its care, and is currently caring for over 200 dogs. With rising costs and dropping temperatures, the charity is calling for urgent support.

It costs the charity £6,000 per day to continue its work.

Fi Harrison, head of fundraising and communications, said: "It's heart-breaking for our team to see the conditions some dogs arrive in. We really are their last chance and hope of survival."

More information about the appeal can be found here.

FIVP to represent independent practices at London Vet Show

The Federation of Independent Veterinary Practices (FIVP) will be at stand (S05) at this year's London Vet Show.

The not-for-profit organisation will be explaining how its expertise and resources can help independent practices to thrive in a competitive industry. It will also share how it has been representing independent practices in the ongoing CMA investigation.

On Thursday, FIVP member Steve Carter will be available to discuss how veterinary surgeons and nurses can pursue practice ownership.

FIVP will also be offering independent practices three months of free membership if they sign up at the stand.

Rita Dingwall, FIVP business development manager, said: "It's a wonderful opportunity to discuss our representation in the CMA enquiry and connect with like-minded individuals who share our passion for independent practice."
