Spring outbreak of atypical myopathy cases!

The toxin responsible for atypical myopathy is also contained in sycamore seedling (Acer pseudoplatanus (= maple tree; see pictures). Currently, there are large number of sycamore seedlings coming through.

So, it is imperative to avoid that equidae (horses, donkeys, zebras…) ingest them. It is important to browse your grass to make sure it does not contain these seedlings but if that is the case, you may try to mow or burn them.

The number of cases of atypical myopathy is increasing these days. Please forward the message below to your contacts through your Facebook account.

If you are aware of a case, THANK YOU to declare the case:

– as an owner, via the link : http://labos.ulg.ac.be/myopathie-atypique/en/declare-case-owners/

– as a vet, via the link : http://labos.ulg.ac.be/myopathie-atypique/en/veterinarians/declare-case-veterinarian/

SPRING 2017 – At the date of the 28 of April 2017, 144 clinical cases compatible with the diagnosis of atypical myopathy have been communicated to Liege University and to the RESPE.  These cases were recorded in Belgium (18 cases) and France (93 cases), Great-Britain (9 cases), The Netherlands (2 cases), In Ireland (2 cases), in the Czech Republic (12 case), In Switzerland (1 case) and Germany (7 cases).


Following research that was supported by The Horse Trust, the Comparative Neuromuscular Diseases Laboratory(www.rvc.ac.uk/research/laboratories/comparative-neuromusculardiseases-laboratory/diagnostic-services) of the Royal veterinary College of London (UK) now offer vets serum testing for the hypoglycin A toxin and its principal metabolite named MCPA-carnitine known to cause atypical myopathy. Horses affected by atypical myopathy present a particular biochemical profile in urine and blood. The laboratory also offers urine organic acid and plasma acyl carnitine profile testing to support the diagnosis. Samples need to be submitted by vets. Further details and prices can be found on the lab website (http://www.rvc.ac.uk/research/laboratories/comparative-neuromuscular-diseases-laboratory/diagnostic-services).

Plant samples can also be tested for hypoglycin A. Please go the “Plant sample testing” (http://www.rvc.ac.uk/Media/Default/Comparative%20Neuromuscular%20Diseases%20Laboratory/atypical-myopathy-information-sheet-correct-logo.pdf) for further information
