Check any Introductory Parasitology textbook eg "Foundations of
Parasitology" by Roberts and Janovy. Most libraries will have the
information you seek. If you live close to a university the library there
will have all the information you want. The web has a comparatively small
amount of information of uncertain quality relative to what is available
in a library. This next comment is not meant as a flame, but, shouldn't
this research represent your efforts in finding the information?

To be without some of the things you want is an
indispensable part of happiness.
