Haemonchus contortus & friends

[Russell Farris]

        Is there an online list of parasites with descriptions? At the
moment I'm interested in Haemonchus contortus because it stimulates the
production of cortisol in its host. It is the only cortisol-stimulating worm
I have found in PubMed, although Strongyloides stercoralis may be another.
Thanks,

Russ
