First, I will briefly review the ways in which parasites can be functionally important for the free-living animals in a community. Parasites may multiply by asexual division (fission/splitting or internal/endogenous budding) or sexual reproduction (formation of gametes and fertilization to form zygote, or unique process of conjugation where ciliates exchange micronuclei). In contrast to fecal-oral transmission, where infective stages are excreted into the environment, potential new hosts would not normally come into contact with the parasite. And like any member of your family, it’s important to keep your companion animal healthy and free of parasites.
