Breeding for resistance may control bTB in Africa – study
Breeding for resistance could help to control bTB in Africa.
DNA analysis finds resistance is not necessarily linked to a specific breed of cattle.

Breeding for resistance to tuberculosis (bTB) may help to control the disease in Africa, according to new research.

Writing in the journal Frontiers in Genetics, researchers describe their study in which they compared the DNA of 212 cattle in Cameroon, of which 153 had tested positive for Mycobacterium bovis, the bacteria that cause bTB. 

The study revealed that some of these animals’ genetic makeup conferred a higher level of resistance against bTB. Researchers also found that while there were clusters of animals that differed in their resistance to bTB, there were no apparent differences between breeds. 

Dr Rebecca Callaby from the Centre of Tropical Livestock Genetics and Health (CTLGH) and the Roslin Institute, said: “Our results suggest that resistance to bTB is not necessarily linked to a specific breed of cattle and that resistance to this disease is probably influenced by more than one gene. 

“We hope with further research we will better understand the factors underlying bTB resistance to help to breed healthier cattle and subsequently improve the lives of smallholders in Africa.”

Tuberculosis is estimated to infect an estimated 70,000 people ever year in Africa. In Cameroon, the prevalence is rising and, with no effective vaccine or treatment, breeding for resistance for bTB could help to control the disease.

Selective breeding has already been implemented in other countries, including the UK, where the dairy industry recently introduced a genetic evaluation index that enables farmers and breeders to select Holstein dairy bulls with greater bTB resistance.

Rabbit Awareness Week set to return this summer

News Story 1
 Rabbit Awareness Week (RAW) is returning this summer, running from 24-28 June 2024. The theme for this year will be 'Healthy Diet, Happy Bunnies'.

The focus on rabbits' diet comes after the most recent PDSA Animal Wellbeing (PAW) Report report revealed that 42 per cent of veterinary professionals identified inappropriate diet as one of the five most important rabbit welfare issues that need to be address.

The campaign will include veterinary blogs, videos, and digital waiting room resources. Practices can sign up to receive updates about RAW.

CVS Group hit by cyber attack

CVS Group, which owns more than 450 veterinary practices in the UK, has been hit by a cyber attack.

In a statement, the group said the incident involved unauthorised external access to a limited number of its IT systems. As soon as the attack was discovered, the group took its IT systems temporarily offline, causing 'considerable operational disruption'.

It has warned that the security steps taken and ongoing plans to move its operational systems and IT infrastructure to the Cloud are likely to have an ongoing impact over a number of weeks.

Due to the risk that personal information was accessed, CVS has informed the Information Commissioner's Office. The company is working with third party consultants to investigate the incident.
