Since the parasite we are talking about is frog hookworms (a nematode) I was wondering what is it's life cycle? In particular; how long will it take for hookworm eggs to hatch once laid in feces, can they go dormant and for how long, and how long after eggs hatch will the larvae survive without a host?

My train of thought is as follows. Once you know the life cycle of a parasite, you can apply the medication at the right time and interval. There is a variation of dosage intervals across the board from what I read. With fish you have to hit the nematodes once a week for 4 consecutive weeks and that is independent of medication or it's dosage; it's based on fish nematodes life cycles. So what is the correct one for frogs ?

I did search in the net, but did not found the answer needed to go forward, so will try to search in the EDU domains next week. Would appreciate if anyone has any info to share about the frog hookworm life cycle, thank you !
