“Alert vets and fast scientific analysis is our essential line of defence. Vets are completely key to stopping invasion and institution of recent parasites within the UK, and it’s important they realise this.”

A spread of things are rising the probability of the unfold of D repens, Prof Morgan mentioned, together with elevated pet journey and relocation on account of progressive rest of the Pet Journey Scheme (PETS).
