With anecdotal evidence of an increase in joint-ill, a disease affecting the joints of young lambs, investigators from Scotland's Rural College are offering free post mortem tests to sheep farmers and their vets who suspect their lambs are infected.

SAC Consulting Veterinary Services has decided to collect up-to-date information from across the country about which pathogens are responsible for outbreaks and the most appropriate antibiotic to treat them with.

As an easily recognised disease farmers or their vets do not normally submit cases to any of the eight Veterinary Disease Surveillance Centres run by SAC Consulting . However, the offer of free tests should help the vets gather enough evidence for a proper scientific survey and analysis during the 2017 lambing season.

Many different bacteria may be associated with the disease, with Streptococcus dysgalactiae the most common. Normal practice is to use preventative antibiotics, but increasing concerns about anti-microbial resistance to them means that approach is no longer acceptable and treatments need to be more targeted. Hopefully the research will help in the development of Health Plans with new prevention and control strategies.
