Wow, I loved Georgi's, really helped me get through the class. Gave just about enough information, without going too far into detail. Now, there are some nice picture books for identification of oocysts and worms, but they don't go into that level (lifecycle) of detail either.
I would use Georgi's, and for more detail try the CDC website for PPP's and Lifecycles of specific organisms. If you still need more, Pub Med or Google Scholar would be by go to, but unless you are considering a career in parasitilogy, I think any other book might be a waste of $$ and certainly time.
