“…Based on the 733 bp long alignment all Clinostomum metacercariae obtained from both fishes and amphibians were identical in ITS1 region with the exception of a single base difference in one individual. Our ITS1 sequences were identical to previously published sequences of adult and larval specimens of Clinostomum marginatum (Rudolphi, 1819) from multiple host species and locations available in GenBank (Caffara et al , 2011; Sereno-Uribe et al , 2013; Pérez Ponce de León et al , 2016; Rosser et al , 2017). We were able to successfully amplify and sequence partial cox 1 gene from seven of our extracts from different hosts and locations (table 1).…”

“…Although classical studies contend that species identity varies as a function of intermediate host identity (amphibians vs fishes), our findings indicated that C. marginatum often infects amphibians as well as fishes in the same habitats. Prior to recent molecular studies (Caffara et al , 2011; Sereno-Uribe et al , 2013, 2018; Pérez Ponce de León et al , 2016; Rosser et al , 2016, 2017), Clinostomum species determination was often based on geographical location (New vs Old World) and intermediate host identity (fishes vs amphibians) (Yamaguti, 1933; Hunter and Hunter, 1935; McAllister, 1990). Alongside the findings of Bonnet et al (2011), our results indicate that C. marginatum frequently infects both amphibians and fishes that co-occur in the same aquatic environment.…”

“…Members of other snail genera and families (e.g. Lymnaea, Radix , Bulinus, Biomphalaria ) have also been reported as hosts, albeit less commonly (supplementary table 2; Esch et al , 2001; Caffara et al , 2011; Pinto et al , 2015; Rosser et al , 2017). Sporocysts release free-swimming cercariae that can infect a broad range of amphibian and freshwater fish species (supplementary table 3; Hoffman, 1999; McAllister et al , 2010), within which they form loosely encysted metacercariae (Kanev et al , 2002).…”

Patterns ofClinostomum marginatuminfection in fishes and amphibians: integration of field, genetic, and experimental approaches

Digenetic trematodes of the genus Clinostomum are cosmopolitan parasites infecting fishes, amphibians, reptiles, and snails as intermediate hosts. Despite the broad geographical distribution of this genus, debate about the number of species and how they vary in host use has persisted. To better understand patterns of infection among host species and across life stages, we used large-scale field surveys and molecular tools to examine five species of amphibians and seven species of fishes from 125 California ponds. Among the 12,360 examined hosts, infection was rare, with an overall prevalence of 1.7% in amphibians and 9.2% in fishes. Molecular evidence indicated that both groups were infected with Clinostomum marginatum. Using generalized linear mixed effects models, host species identity and host life stage had a strong influence on infection status, such that Lepomis cyanellus (green sunfish) (49.3%) and Taricha granulosa (rough skinned newt) (9.2%) supported the highest overall prevalence values, whereas adult amphibians tended to have a higher prevalence of infection relative to juveniles (13.3% and 2.5%, respectively). Experimentally, we tested the susceptibility of two amphibian hosts (Pseudacris regilla [Pacific chorus frog] and Anaxyrus boreas [western toad]) to varying levels of cercariae exposure and measured metacercariae growth over time. Pseudacris regilla was 1.3× more susceptible to infection, while infection success increased with cercariae exposure dose for both species. On average, metacarcariae size increased by 650% over 20 days. Our study highlights the importance of integrating field surveys, genetic tools, and experimental approaches to better understand the ecology of host–parasite interactions.

Pathology associated with three newClinostomummetacercariae from Argentina with morphological and DNA barcode identification

In the Laboratory of Parasites of Fishes, Crustaceans and Mollusks (CEPAVE), we undertook a parasitological study on three species of fish from the Espinal and Esteros del Iberá ecoregions of Argentina. Clinostomid metacercariae were found parasitizing Characidium rachovii, Crenicichla vittata and Gymnogeophagus balzanii. In this study, we analysed the damage that these parasites inflict on their hosts through the evaluation of histological sections. In addition, Clinostomum metacercariae were identified using morphological characters and DNA barcoding. In the pathological analysis, we observed that muscle tissue was the most affected. The inflammatory response showed vascular congestion areas and infiltration of numerous inflammatory cells, mainly lymphocytes. The molecular and morphological approach supports the presence of three new lineages of clinostomid metacercariae in Argentina. This could lead to the discovery of a high number of lineages or species of Clinostomum from South America.

Great cormorants Phalacrocorax carbo were found dead in a goldfish farm in Aichi Prefecture. They were infected with trematodes in the oral cavity. Based on morphological observation and genetic analysis, the trematodes were identified as Clinostomum complanatum. This is the first case reporting C. complanatum infection of great cormorants in Japan. Heavy metacercarial infection of goldfish was found in the same fish farm. The metacercariae were shown to be the same species as the adult worms from the bird by molecular analysis. These results suggest that great cormorant is involved in the life cycle of this trematode in farmed goldfish.
