“…These researchers have also contributed to the taxonomic knowledge about some taxa, such as Monogenea (Irigoitia et al ., 2014), Nematoda (Timi et al ., 2014) and Acanthocephala (Braicovich et al ., 2014). In Buenos Aires there are two groups working on helminths from fish, one that has been studying the taxonomy of cestodes (Gil de Pertierra et al ., 2015; Menoret & Ivanov, 2015), and one that has been working on digeneans, including their taxonomy (Arredondo & Ostrowski de Núñez, 2013) and life-cycle surveys (Quintana & Ostrowski de Núñez, 2016).…”

Helminth parasites of South American fishes: current status and characterization as a model for studies of biodiversity

et al. 2016

The South American subcontinent supports one of the world's most diverse and commercially very important ichthyofauna. In this context, the study of South American fish parasites is of increased relevance in understanding their key roles in ecosystems, regulating the abundance or density of host populations, stabilizing food webs and structuring host communities. It is hard to estimate the number of fish parasites in South America. The number of fish species studied for parasites is still low (less than 10%), although the total number of host-parasite associations (HPAs) found in the present study was 3971. Monogeneans, with 835 species (1123 HPAs, 28.5%), and trematodes, with 662 species (1127 HPAs, 30.9%), are the more diverse groups. Data gathered from the literature are useful to roughly estimate species richness of helminths from South American fish, even though there are some associated problems: the reliability of information depends on accurate species identification; the lack of knowledge about life cycles; the increasing number of discoveries of cryptic species and the geographically biased number of studies. Therefore, the closest true estimations of species diversity and distribution will rely on further studies combining both molecular and morphological approaches with ecological data such as host specificity, geographical distribution and life-cycle data. Research on biodiversity of fish parasites in South America is influenced by problems such as funding, taxonomic impediments and dispersion of research groups. Increasing collaboration, interchange and research networks in the context of globalization will enable a promising future for fish parasitology in South America.

“…Because other mollusc species inhabit the UPRF, Aylacostoma chloroticum (Scott, 1954) is an interesting potential host candidate for digeneans because it has been registered as an intermediate host of Pseudosellacotyla lutzi (Freitas, 1941), Neocladocystis intestinalis (Vaz, 1932), Stephanoprora aylacostoma and the Echinostoma group (Quintana & Núñez, 2008, 2014, 2016; Pinto & Melo, 2013a) and it is native to this environment. This mollusc is currently considered an endangered species according to the IUCN Red List of Threatened Species (Mansur, 2000), and in South America it is part of a conservation breeding programme called the Aylacostoma Project (Vogler et al ., 2014).…”

Molecular characterization and identification of digenean larval stages in Aylacostoma chloroticum (Prosobranchia: Thiaridae) from a neotropical floodplain

et al. 2019

Digeneans (Trematoda: Digenea) are endoparasites that present a complex life cycle, generally involving an intermediate invertebrate host and a vertebrate host. There is limited information about which species of molluscs may act as intermediate hosts in the upper Paraná River floodplain (UPRF), where Aylacostoma chloroticum can be considered a potential candidate. The study of digeneans in this region is important because some of these parasites are potentially zoonotic, and, therefore, are relevant to public health. However, the correct identification of these organisms during the larval stages is difficult because of the lack of morphologically diagnostic characteristics. The objective of this study was to identify and molecularly characterize the larval stages of digeneans found in A. chloroticum in the UPRF, using the mitochondrial marker of subunit I of cytochrome c oxidase and the 28S nuclear marker. The molluscs were examined in the laboratory and three morphotypes of cercariae were found. DNA was extracted from the specimens obtained and was then amplified and sequenced. The morphotypes exhibited high genetic similarities with Pseudosellacotyla, Paralecithodendrium and Philophthalmus, indicating that these organisms belong to these genera. This is the first record of larval stages of these genera in molluscs collected in the UPRF.
