==Introduction==
 +
 +
''Onchocerca cervicalis'' affects the skin indirectly when either the microfilaria or the larvae are deposited in the skin capillaries. In the latter case the effects are limited and most obvious following administration of an avermectin
 +
wormer.
 +
 +
==Clinical signs==
 +
 +
The classical signs include '''ulcerating skin nodules''' in the '''withers''' region (<u>fistulous withers</u> involving the withers bursa) or the '''skin overlying tendons of the limbs'''.
 +
 +
==Diagnosis==
 +
 +
Onchocerca can be difficult to diagnose.
 +
 +
==Treatment==
 +
 +
Treatment is limited to the use of [[Macrocyclic Lactones|avermectins]] administered orally. Donkeys that receive regular
 +
avermectin wormers are usually not affected and so this history is useful to establish.
