“…One of the two parasites, R. campanula, has been frequently reported in duck mussels (Taskinen & Valtonen, 1995;Taskinen et al, 1997;Taskinen, 1998) and closely related species (Richardson, 1990), but the larvae of trematodes from the Phyllodistomum genus have only occasionally been found in this species of mussels (Taskinen et al, 1991). Phyllodistomum larvae have been reported in swan mussels A. cygnea (Orecchia et al, 1975), zebra mussels D. polymorpha (Laruelle et al, 2002), and North American unionids (Grizzle & Brunner, 2009 Fig. 3 The proportion of A. anatina infected with trematode larvae differed among lakes (A), and females were more heavily infected than males (B).…”

“…Although the role of digenean trematodes in the ecology and evolution of freshwater communities has been addressed by many studies of gastropods (Jokela & Lively, 1995;Sorensen & Minchella, 2001;Hechinger & Lafferty, 2005), interactions between digenean trematodes and their bivalve hosts remain relatively poorly understood. We now know that bivalves are used as intermediate hosts by several families of digenean trematodes (Overstreet & Curran, 2002;Campbell, 2008;Grizzle & Brunner, 2009). For example, swan mussels (Anodonta cygnea) serve as the intermediate host of the digenean trematode Phyllodistomum elongatum (Gorgoderidae), and zebra mussels (Dreissena polymorpha) are the intermediate host of Phyllodistomum folium (Orecchia et al, 1975;Laruelle et al, 2002).…”

Factors affecting trematode infection rates in freshwater mussels

et al. 2014

Mussels are intermediate hosts of digenean trematodes, but determinants of these infections remain unknown. To address this problem, we collected duck mussels Anodonta anatina in eighteen lakes from northeastern Poland and examined how mussel age, sex, and the encrustation with zebra mussels Dreissena polymorpha and environmental conditions in lakes influenced infection rates. We also assessed parasitic preferences to host gonads and hepatopancreas and the impact of parasites on female fertility. Mussels were infected with Rhipidocotyle campanula and Phyllodistomum sp. Infection rates were higher in older and female mussels but were unrelated to the biomass of encrusting D. polymorpha and the trophy, thermal conditions, and Ca 2? availability. Parasites occupied gonads more often than hepatopancreas. Infected females were less likely to carry glochidia and incubated fewer glochidia. We suggest that the risk of infection by digenean trematodes increases with the amount of water processed by filter-feeding hosts and/or that parasites actively seek hosts which can provide them with abundant resources. This mechanism explains why parasites more often occupied older and female mussels and targeted their gonads. Future research on trematodemussel interactions should integrate knowledge on different elements of the complex trematode life cycles, including effects of higher-order hosts such as fish.

“…Within freshwater ecosystems, attention has begun to focus on important emerging diseases (Okamura & Feist, 2011) complementing the already extensive literature that exists on a wide range of wellestablished animals parasitic on vertebrates and invertebrates, e.g. Lapage (1961), Chubb (1979), Grizzle & Brunner (2009). Parasites are now recognized as major components of ecosystems, both in terms of total biomass and especially in food web dynamics (Lafferty et al, 2006Szuroczki & Richardson, 2009).…”

Cercariae (Platyhelminthes: Trematoda) as neglected components of zooplankton communities in freshwater habitats

Zooplanktonic animals live in the open water of freshwater habitats, whilst trematodes are ubiquitous parasitic worms of aquatic vertebrates and invertebrates. A defining characteristic of trematode life cycles is the cercariae, a mainly planktonic freeliving larval stage that emerges into the aquatic environment from infected molluscan hosts. Cercariae are lecithotrophic (non-feeding) larvae analogous of meroplankton. Although millions of planktonic cercariae enter freshwater habitats on a daily basis and are capable of forming into dense clouds, they are a largely neglected component of the zooplankton community, rarely mentioned in faunal studies. Nevertheless, there is increasing evidence to suggest that cercariae have important secondary roles in aquatic food webs and energy transfer. This article reacquaints freshwater biologists with cercariae, highlighting the key characteristics of their biology and population dynamics, their role in food webs, public health and veterinary importance, and the risk of increased population densities under the influence of climate change. The reasons for their neglect in freshwater biology is evaluated and considered to be associated with zooplankton sampling methodologies being unsuitable for collecting cercariae and the paucity of identification keys in the limnological literature.

“…Similarly, few reviews have summarized the ecology and diseases of freshwater molluscs (Dillon, 2000(Dillon, , 2006, especially for those groups that are ecologically important such as freshwater bivalves, especially mussels (see Grizzle and Brunner, 2009).
