| + | === ''ONCHOCERCA'' SPECIES === |
| + | ==== General ==== |
| + | *One species, ''O. cervicalis'' (= ''O.reticulata''). |
| + | *Large filarial nematode (<30cm); ligamentum nuchae (and limb connective tissue). |
| + | |
| + | ==== 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. |
