Sheep scab: update on diagnosis and investigating suspected lack of efficacy of Macrocyclic Lactones (MLs)

Sheep scab is the most important ectoparasitic disease of sheep in the UK, representing a significant threat to both animal welfare and farm economics. Sheep scab is currently endemic in the UK and a notifiable disease in Scotland, while for England and Wales, it is a criminal offence to fail to treat sheep visibly affected by scab or to move them off the holding, other than direct to slaughter.
