capilllariia spp - pig hairworms pictures please

hi all
i hope somebody can help!
our pet pig bessie has recently loosely been diagnosed with a pig hair worm?

stupidly i have only ever used lots of ivermection, some fenbendozle & the vet now recommends a levamisole product.

i cannot find any pictures of the pig hair worm or capilliariia spp?

can anybody show me the beasty that is making my bess sick?
thanks
