Abstract:

The Zoogonidae is the only digenean family where known cercariae lack the tail but actively search for the second intermediate host. However, the data on the zoogonid life cycles are scarce. In the present study, we elucidated and verified life cycles of the Zoogonidae from the White Sea. Using rDNA data, we showed that Pseudozoogonoides subaequiporus utilizes gastropods from the family Buccinidae as the first intermediate host and protobranch bivalves as the second one. This life cycle can be facultatively truncated: some cercariae of P. subaequiporus encyst within the daughter sporocysts. Molecular data also confirmed previous hypotheses on Zoogonoides viviapus life cycle with buccinid gastropods acting as the first intermediate hosts, and annelids and bivalves as the second intermediate hosts. We demonstrated the presence of short tail primordium in the developing cercariae of both species. Based on the reviewed and our own data, we hypothesize that the emergence of tailless cercariae in the evolution of the Zoogonidae is linked to the switch to non-arthropod second intermediate hosts, and that it possibly happened only in the subfamily Zoogoninae. Basally branching zoogonids have retained the ancestral second intermediate host and might have also retained the tail.

Abstract:

Anarhichotrema Shimazu, 1973 is a monotypic digenean genus, with the type- and only species, Anarhichotrema ochotense Shimazu, 1973, known to infect North Pacific fishes. This genus was originally described as a member of the Lissorchiidae (Monorchioidea) and later moved to the Zoogonidae (Microphalloidea). Its exact phylogenetic position has remained unresolved due to the lack of molecular data. In this study, we isolated specimens of A. ochotense from the Bering wolffish, Anarhichas orientalis Pallas, 1814 caught in the Sea of Okhotsk, described them morphologically and performed a molecular phylogenetic analysis of their nuclear 18S and 28S rDNA regions. The specimens examined in our study generally corresponded to previous morphological descriptions of A. ochotense but were noticeably smaller, possibly due to the crowding effect. The phylogenetic analysis placed Anarhichotrema within the Lissorchiidae as a sister taxon to the group comprising freshwater lissorchiids. Thus, we restore Anarhichotrema to the Lissorchiidae, as originally assigned.

Abstract:

AbstractDiphtherostomum brusinae was first recorded by the present study in the north of Portugal. Sporocysts, containing cercariae and encysted metacercariae, were observed in the gonads and digestive gland of the gastropod Nassarius reticulatus. Metacercariae were also found infecting the foot, mantle border and gills of the cockle Cerastoderma edule. The adult form was lodged in the rectum of the definitive host Diplodus sargus. The morphology of the three parasitic stages was studied by light (LM) and scanning electron microscopy (SEM). Despite the close similarity between cercaria and metacercaria, SEM data provided information that allowed their differentiation, namely the presence of a dense crown of microvilli around the oral cavity of the cercariae, which was absent in the metacercariae. In addition, the metacercariae presented a specific pre-acetabular rectangular band with conspicuous triangular spines. The adult showed characteristics of D. brusinae species, in particular the presence of acetabular lips, compact vitellaria and large elliptical eggs. Sequenced ITS1 data clearly demonstrated that the cercariae and metacercarial cysts from N. reticulatus, the cysts from C. edule and the adult isolated from D. sargus were life cycle stages that belonged to the same species, i.e. D. brusinae. Two transmission strategies in the life cycle of this species were observed: (1) cercariae encyst within the sporocysts of N. reticulatus and await ingestion by the definitive host; and (2) N. reticulatus naturally emits cercariae; they encyst in C. edule or the environment and are ingested by the definitive host.

Abstract:

AbstractSpecimens of the fishes Scarus ghobban Forsskål (Scaridae) and Crenimugil crenilabis Forsskål (Mugilidae) were caught in the Red Sea off the coast of Sharm El-Sheikh, South Sinai, Egypt. Ten (20 %) and 15 (50 %) of these fishes, respectively, were found to harbour intestinal trematodes. Scarus ghobban was parasitised by Prosteganoderma brayi gen. nov., sp. nov. (Zoogonidae) and C. crenilabis by Forticulcita mugilis sp. nov. (Haploporidae). Prosteganoderma gen. nov. is similar to Steganoderma Stafford, 1904, but clearly differs from it and from all the other genera of the subfamily Lepidophyllinae Stossich, 1903 in having a large ventral sucker surrounded by a large prominent fleshy fold of the body wall and a pre-testicular uterus. Forticulcita mugilis sp. nov. is similar to F. glabra Overstreet, 1982, the type and the only species of the genus, but clearly differs in having a larger body size, a longer forebody, an intestinal bifurcation in the middle of the body, subequal gonads, Laurer’s canal opening dorsally at a considerable distance posterior to the testis and a much larger egg size.

Abstract:

Diphterostomum brusinae (Zoogonidae) is a digenean species that has been recorded worldwide parasitizing marine fishes. Several species have been synonymized with D. brusinae because they lack conspicuous morphological differences. However, due to the breadth of its geographic distribution and the variety of hosts involved in the life cycles, it is likely to be an assemblage of cryptic species. Diphterostomum flavum n. sp. is described here as a morphologically cryptic relative of D. brusinae, in the fish Pinguipes brasilianus (Pinguipedidae) off the Patagonian coast, Southwestern Atlantic Ocean, and its life cycle is elucidated through morphology and molecular analysis. This species uses the gastropod Buccinanops deformis (Nassariidae) as first and second intermediate host with metacercariae encysting within sporocysts. They also, however, use the polychaete Kinbergonuphis dorsalis (Onuphidae) as second intermediate host. No morphological differences were found between adults of D. flavum n. sp. and D. brusinae; however, the number of penetration glands of the cercariae, a diagnostic feature, differed (9 vs. 3 pairs), as well as the ITS2 sequences for the two species. This work provides morphological and molecular evidence of cryptic diversification among species described as D. brusinae, in which the only clear differences are in larval morphology and host spectrum. The strict specificity to the snail acting as the first intermediate host and the variety of fishes with different feeding habits acting as definitive hosts support the likely existence of multiple cryptic species around the world.

Abstract:

AbstractThis article aims at reconstructing the most damaged part of the Strasbourg papyrus of Empedocles (fragment f-d), by taking into account all the parameters at our disposal: palaeography, metre and, of course, content. According to this attempt, Empedocles would be describing the very moment in the phase of increasing Strife when the whole-natured creatures (the ολοφυ) were split into male and female beings. Thus, the first part of the fragment becomes very similar, in its content, to fr. 62 D.-K. and to Plato’s parody of Empedocles in Aristophanes’ myth in the Symposium, while its second part emerges as containing new details of the process by which double creatures were split into two. If this reconstruction is accepted, its implication will be that Aetius’ presentation of Empedocles’ cosmic cycle as a fourfold continuous process is deeply inadequate.

Abstract:

AbstractLarval trematodes are the main parasites of snails, and they play a crucial role because they usually castrate their snail hosts and can thus alter their population and community dynamics. This study involved a survey of seven gastropod species (Crepipatella dilatata,Fissurella radiosa,Nacella magellanica,Pareuthria fuscata,Siphonaria lessonii, S. lateralisandTrophon geversianus) parasitized by 12 trematode species (one hemiurid, one gymnophallid, two lepocreadiids, two microphallids, one notocotylid, two renicolids, one philophtalmid, one schistosomatid and one zoogonid) from southern Patagonia (47°S, 65°W), Argentina. OnlyF. radiosawas free of parasites. The study included the description of five new larvae, based on morphological and molecular information, and a comparison of the parasite diversity with that of a northern locality (42°S, 64°W), characterized by a lower mollusc diversity. Species richness and diversity of parasites were higher in the southern site. This suggests a correlation between the level of parasitism and the diversity of molluscs (first intermediate hosts), which is higher at the high-latitude site and seems to attract shorebirds, which disperse the digenean eggs and facilitate the completion of their life cycles. These results support the notion that parasitism is influenced by large-scale factors such as biogeographical patterns, and small-scale factors such as diversity or abundance of intermediate and definitive hosts.

Abstract:

Abstract The assassin snail genus Anentome is widespread in Southeast Asia, and is distributed all over the world via the aquarium trade. One species of genus Anentome, Anentome helena, is known to act as intermediate host of parasitic trematodes. This study investigates the taxonomic diversity of larval trematodes infecting A. helena and Anentome wykoffi in Thailand. Larval trematodes were identified by combining morphological and DNA sequence data (cytochrome c oxidase I and internal transcribed spacer 2). Species delimitation methods were used to explore larval trematode species boundaries. A total of 1107 specimens of Anentome sp. were collected from 25 localities in Thailand. Sixty-two specimens of A. helena (n = 33) and A. wykoffi (n = 29) were infected by zoogonid cercariae, heterophyid metacercariae and echinostome metacercariae, with an overall prevalence of 5.6% (62/1107) and population-level prevalences in the range of 0.0–22.3%. DNA sequence data confirmed that the larval trematodes belong to the families Echinostomatidae, Heterophyidae and Zoogonidae. As such, this is the first report of zoogonid cercariae and heterophyid metacercariae in A. helena, and echinostome metacercariae in A. wykoffi. Moreover, this study provides evidence of tentative species-level differentiation between Thai Echinostoma sp. and Cambodian Echinostoma mekongi, as well as within Echinostoma caproni, Echinostoma trivolvis and Echinostoma revolutum.

Abstract:

El objetivo de este estudio fue determinar la presencia de parásitos metazoarios y epibiontes en el ostión del placer <em>Crassostrea corteziensis</em> (Hertlein, 1951) en dos localidades costeras y pesqueras del estado de Sinaloa, en el noroeste del Pacífico mexicano. Se colectaron 30 ostiones en la cooperativa pesquera de “Playa norte” en la bahía de Mazatlán, Sinaloa y se realizó una comparación con la presencia de parásitos en ostiones en la laguna costera de “Ceuta”. La inspección de ostiones en la laguna costera reveló la presencia de 36 metacercarias encapsuladas de la familia Acanthocolpidae en la gónada del ostión <em>C. corteziensis</em>. En la bahía de Mazatlán, en la zona de Playa norte, se encontraron seis metacercarias: tres de la sp. 1 (pertenece a la familia Hemiuridae) en el manto, un espécimen de sp.2 (Familia Fellodistomidae) en la glándula digestiva y una metacercaria sp3. no identificada en el manto, una metacercaria de (Familia Zoogonidae) en la glándula digestiva, dos nemátodos de vida libre del género <em>Theristus </em>sp. Como organismos epibiontes se encontraron siete ejemplares de poliquetos de la familia Nereididae en la concha de los ostiones. Este trabajo reporta por primera vez la invasión del digeneo <em>Stephanostomum</em> sp. Looss, 1899 de la familia Acanthocolpidae parásito de la gónada del ostión <em>C. corteziensis</em> en el Pacífico mexicano. Así como, la presencia de digeneos pertenecientes a la familia Fellodistomidae, Hemiuridae y Zoogonidae. Los resultados de este trabajo contribuyen al conocimiento en la biología, la biodiversidad y la preferencia del hospedero de estos parásitos, con posibles implicaciones en los riesgos para la salud que plantea el consumo humano del ostión del placer, con gran regionalización en el consumo de mariscos crudos que presentan amplia identidad social gastronómica en estas zonas costeras en el Pacífico mexicano.

Abstract:

AbstractOver a two-years period, a survey was carried out in order to increase the knowledge of digeneans parasitising the commonest intertidal gastropods on the Patagonian coast, Southwestern Atlantic Ocean. A total of 4,725 gastropods were examined. Six species of digenean parasitising four snail species were found; four of them were registered for first time: Maritrema sp. 1 (Microphallidae) in Crepidula dilatata (Calyptraeidae), Parorchis sp. (Philophtalmidae) and sporocyst of Renicolidae in Trophon geversianus (Muricidae), and Diphterostomum sp. (Zoogonidae) in Buccinanops globulosus (Nassariidae). Two other species were found in Siphonaria lessoni (Siphonariidae): Maritrema sp. 2 and Hemiuridae. One snail species, Tegula patagonica (Trochidae) was not parasitised. These gastropods act as first intermediate host, and C. dilatata, S. lessoni and B. globulosus also frequently host metacercariae within the sporocyst. Overall prevalences varied from 0.16% of Diphterostomum in the intertidal population of B. globulosus to 33.45% of Maritrema sp. 1 in C. dilatata.

Abstract:

AbstractA total of 24 digenean species belonging to 10 distinct families (Derogenidae, Faustulidae, Fellodistomidae, Gyliauchenidae, Hemiuridae, Lepocreadiidae, Mesometridae, Monorchiidae, Opecoelidae and Zoogonidae) were recorded in sparid fishes from Bizerte Lagoon (northern Tunisia). The diversity of the digenean fauna of sparid fishes from this locality is compared to that recorded from the Gulf of Tunis. Prodistomum polonii, not detected before, was found in Sarpa salpa. Aphallus rubalo, Derogenes latus, Holorchis micracanthum and Pachycreadium carnosum previously recorded from sparid fishes on the Tunisian coasts were absent during this study. Allopodocotyle pedicellata, Lepocreadium pegorchis, L. album, Proctoeces maculatus, Magnibursatus bartolii and Macvicaria maillardi were reported in hosts not previously reported for the Gulf of Tunis. Generally, prevalence was higher in fishes from Bizerte Lagoon but abundance and mean intensity were higher in Gulf of Tunis. Except for Lithognathus mormyrus, Sarpa salpa and Sparus aurata from Bizerte Lagoon, which show higher digenean diversity, the other sparid fishes have a lower diversity compared to those from Gulf of Tunis. The species richness of digeneans in B. boops was the same in the two areas studied.

Abstract:

Steganoderma eamiqtrema n. sp. and a single unidentified specimen of Steganoderma Stafford, 1904 (Zoogonidae: Lepidophyllinae) obtained from the intestine of the greenstriped rockfish, Sebastes elongatus Ayres, 1859, and the flag rockfish, Sebastes rubrivinctus (Jordan and Gilbert, 1880) (Scorpaeniformes: Sebastidae), collected from 190–200 m depths off Oregon, USA, are described. The new species is distinguished from its seven other congeners by a diagnostic combination of morphological features including an elongate oval to spindle-shaped body, a clavate to comma-shaped cirrus pouch located in the forebody and hindbody, a bipartite seminal vesicle, a bifurcal or just post-bifurcal genital pore, a larger ventral than oral sucker, and a smooth testes and ovary with a relatively small distance between them. We present an updated key to the eight species now in Steganoderma and provide a list of parasites known from Se. elongatus and Se. rubrivinctus. The discovery of S. eamiqtrema in Se. elongatus represents the second species of zoogonid known from this host, and the finding of Steganoderma sp. in Se. rubrivinctus represents the first report of a digenean from this host species. A detailed discussion also is given of the type species, S. formosum Stafford, 1904, and questions are raised as to whether this species has a worldwide distribution and infects such a wide variety of fish hosts. We present evidence including variation we observed in redescriptions of the type species, query the implausible idea that there could be gene flow between conspecific helminths geographically separated in the North Atlantic and North Pacific Oceans over such a vast geological period, and offer the possibility that some prior reports of S. formosum may, indeed, be S. eamiqtrema; all of which suggests S. formosum sensu lato may be part of a species complex and not the same worldwide species. Steganoderma is represented in the deep sea by S. eamiqtrema, S. formosum, and Steganoderma sp., and limited speculation is given as to the host specificity of this genus and life history strategies of the new species in deeper waters. Finally, molecular studies of species of Steganoderma are sorely needed (i.e., there is no DNA sequence data currently available in GenBank for any species of this genus), and we suspect that with further molecular, morphological, and life history work, this genus will be taxonomically divided up.

Abstract:

AbstractLecithostaphylus tylosuri sp. nov. (Digenea, Zoogonidae) specimen were collected from the digestive tract of Tylosurus acus imperialis (Teleostei, Belonidae) caught off the eastern coast of Tunisia. L. tylosuri is very similar to its closest relatives, L. retroflexus and L. nitens. It can be easily distinguished from L. retroflexus (Molin, 1859) in having a more extensive vitellarium, with follicles reaching from the posterior margin of the acetabulum and extending beyond the posterior margin of the testes and a coiled seminal vesicle. L. tylosuri differs from L. nitens as illustrated by Linton 1898, in having a longer cirrus pouch (0.7 mm vs 0.36 mm, respectively) overlapping the anterior edge of the ventral sucker and a submarginal genital pore (submedian in L. nitens). It’s also different from L. nitens as described by Manter 1947 in the vitelline disposition and in having the greater sucker ratio (1: 1.3–2.1 vs 1: 1.3–1.6, respectively). L. tylosuri differs from L. nitens as reported by Machida and Kuramochi 2000 by the absence of variations in the vitellarium disposition in all specimens. L. tylosuri is more similar to L. nitens from group A (considered synonym of L. ahaaha Yamaguti, 1970 = L. nitens by Bray 1987) by having vitelline follicles extending beyond the testes. L. tylosuri can be distinguished from L. ahaaha by its pedunculate rather than prominent acetabulum and its larger body size (4.10–7.85 mm long and 0.75–1.2 mm large vs 2.1–6 mm long and 0.45–1.1 mm large, respectively). The prevalence of L. tylosuri sp. nov. was negatively correlated with host length (decreasing with host size increasing). Host sex does not seem to affect infection parameters.

Abstract:

AbstractFifteen species of digeneans are reported from the waters off the islands of the Outer Hebrides, off north-western Scotland. Trifoliovarium allocytti comb. nov. from Neocyttus helgae is described, figured, and reported for the first time in the northern hemisphere. Brachyenteron helicoleni sp. nov. from Helicolenus dactylopterus is described and considered distinct from other species in the genital pore being at the level of the pharynx, the relatively narrow caeca, the vitellarium being mainly at the level of the ventral sucker and the anterior hindbody, the posteriorly situated, oblique testes, the small amount of post-testicular uterus, the small, delicate cirrus-sac and the large eggs. Derogenes varicus and Lepidapedon arlenae are reported from Caelorhinchus labiatus and Paralepidapedon williamsi is reported from Cottunculus thomsoni for the first time. Steringovermes notacanthi and Prodistomum priedei are reported from off Scotland for the first time. The reports of Derogenes varicus at 1,800 m depth and Zoogonoides viviparus at 1,000 m are deeper records than have previously been published.

Abstract:

Abstract In this study we described two new trematode species, Lecithostaphylus halongi n. sp. (Zoogonidae, Lecithostaphylinae) and Gymnotergestia strongyluri n. sp. (Fellodistomidae, Tergestiinae), on the basis of morphological and molecular data. Adult worms of these two species were collected from, respectively, Hemiramphus spp. (Hemiramphidae) and Strongylura strongylura (Belonidae) caught in the coastal waters of Vietnam. Adult worms of L. halongi n. sp. are morphologically close to Lecithostaphylus gibsoni Cribb, Bray & Barker, 1992 ex Abudefduf whitleyi from Heron Island and Lecithostaphylus depauperati Yamaguti, 1970 ex Hemiramphus depauperatus from Hawaii, but differ from these species in having a larger cirrus sac and a different arrangement of vitelline fields. They also differ from Lecithostaphylus brayi Cabañas-Granillo, Solórzano-García, Mendoza-Garfias & Pérez-Ponce de León, 2020 in the 28S ribosomal DNA (rDNA) sequence data at the interspecific level. Adult worms of G. strongyluri n. sp. ex S. strongylura are morphologically similar to Gymnotergestia chaetodipteri, the only previously known species of this genus, described from Chaetodipterus faber in Jamaica. The new species differs from G. chaetodipteri in body shape, testicular arrangement and the size of the pharynx and eggs. The 28S rDNA-based phylogenetic analysis indicates that G. strongyluri n. sp. is closely related to Tergestia spp., rendering Tergestia paraphyletic. Genetic divergence values between G. strongyluri n. sp. and Tergestia spp. are similar to those among species in the genera Tergestia, Steringophorus and Proctoeces. Our molecular results indicate that G. strongyluri n. sp. and Tergestia spp. may belong the same genus, but additional molecular data are needed for the final conclusion.
