Community Structure : Larval Trematodes in Snail Hosts
In species assemblages of larval trematodes in individual snail hosts, fewer multispecies infections are observed than might be expected by chance. Both interspecific competition and the isolating effect of heterogeneity inrecruitment may explain this pattern of community structure. Here, we analyzed the expected and observed frequency of double infections, using data culled from 62 studies. Ou...
متن کاملPoultry as reservoir hosts for fishborne zoonotic trematodes in Vietnamese fish farms.
Fishborne zoonotic trematodes (FZT) are widespread in Vietnam and Southeast Asia. It is now recognized that the risk of being infected from eating raw fish dishes applies not only to humans, but also to domestic animals (e.g., cats, dogs, and pigs) and fish-eating birds. The role of ducks and chicken, commonly raised on fish farms, as reservoir hosts, however, has not been adequately investigat...
متن کاملA differential staining for living and dead larval trematodes.
In the course of various experiments on larval trematodes, we often confront the necessity for determining their death. In such cases the movement of body, cilia or flame-cells is used commonly as an indicator to determine their death by many parasitologists. However, such movements appear to be not always coincident with the time of the death, consequently results of the diagnosis by such a te...
متن کاملHost diversity begets parasite diversity: bird final hosts and trematodes in snail intermediate hosts.
An unappreciated facet of biodiversity is that rich communities and high abundance may foster parasitism. For parasites that sequentially use different host species throughout complex life cycles, parasite diversity and abundance in 'downstream' hosts should logically increase with the diversity and abundance of 'upstream' hosts (which carry the preceding stages of parasites). Surprisingly, thi...
متن کاملRelative competence of native and exotic fish hosts for two generalist native trematodes
Exotic fish species frequently acquire native parasites despite the absence of closely related native hosts. They thus have the potential to affect native counterparts by altering native host-parasite dynamics. In New Zealand, exotic brown trout Salmo trutta and rainbow trout Oncorhynchus mykiss have acquired two native trematodes (Telogaster opisthorchis and Stegodexamene anguillae) from their...
