Dictyocaulus arnfieldi alone rarely causes clinical problems in donkeys, although it may exacerbate respiratory infections due to other causes. Due to the reported incidence of this parasite in donkeys, particularly when they are co-grazed with horses, where lungworm can cause significant clinical problems, a general control strategy (e.g. with ivermectin) is recommended. | Dictyocaulus arnfieldi alone rarely causes clinical problems in donkeys, although it may exacerbate respiratory infections due to other causes.
