| | + | ==== General ==== |

| − | *In [[Parasitic skin infections - Pathology#Onchocerciasis|skin infections]] | + | ==== Life-Cycle ==== |
| | + | *Indirect LC, similar to that fo cattle ''Onchocerca'' (which are different species). |
| | + | *Intermediate host = midge (''Culicoides'' species). |
| | + | |
| | + | ==== Pathogenicity ==== |
| | + | *Limited significance. |
| | + | *Localised hypersensitivity (oedematous) reaction - to dead/dying microfilariae along ventral abdominal midline (sometimes occurs after ivermectin treatment for general worm control). |
| | + | *Corneal opacity (very rare in UK) - associated with microfilariae. |
