Simon, April 1999 Gabriella's posting: >>I've been reading a textbook: The Foundations of Parasitology, during the past few days. According to the authors (this is the 5th edition), the Camallanus worm requires a copepod as it's intermediary host. The eggs are shed in the feces of the fish. The egg capsules are consumed by the copepods where they develop. Then they are eaten by fish. Treatment is Levamisole. The only way in which this parasite will spread to other fish is via this route.<< You will find this posting and others on the website (thekrib.com) Ken said to have a look at. Helen > Also - does the nematode have other hosts - like snails or daphnia - and > ergo will one treatment be enough to break the life cycle ? Do the worms I > saw in the body of the worm I examined only infect the fish that they > inhabit or will they be able to infect other fish in the absence of other > potential hosts like the above mentions daphnia or copepods etc ? > > Regards, > > Simon Voorwinde ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
