Abstract:
SUMMARYIn the present paper, the phylogeographies of two monogenean species,Pseudokuhnia minorandKuhnia scombri, on the same species of host,Scomber japonicus, were studied. Fragments of the mitochondrial cytochrome c oxidase subunit 1 gene were sequenced for 264 individuals ofP. minorand 224 individuals ofK. scombricollected from 10 localities along the coast of China. Genetic diversity ofK. scombriwas higher than that ofP. minor, which may imply thatP. minorhas a lower evolution rate and/or is a younger species. The neighbour-joining (NJ) trees of both parasites were comprised of two clades without association to sample sites, which is the signature of remixing populations following past division. Analyses of molecular variance and pairwise fixation index revealed different genetic structures for the populations of these two closely related species along the coast of China:P. minorwithout significant genetic structure, whileK. scombrihas some genetic differentiation. Both neutrality tests and mismatch distribution suggested that the populations of these two species of parasites experienced population expansion in the late Pleistocene era due to the glacial–interglacial cycles induced by climatic oscillations.

Abstract:
Four species of Mazocraeoides Price, 1936 including two new species are recorded from clupeiform fishes collected from Visakhapatnam Coast, Bay of Bengal: M. rotundus n. sp. from Ilisha filigera, M. fusiformes n. sp. from Stolephorus indicus, M. prashadi Chauhan, 1950 from Sardinella longiceps and M. dussumieri Mamaev, 1975 from Dussumieria hasselti. Mazocraeoides rotundus n. sp. is differentiated from the previously described species of Mazocraeoides by possessing the following combination of characters: the small pot-like body, the distribution of clamps in the posterior half of body and the genital complex consisting of five pairs of hooks arranged in two vertical rows. It differs from M. prashadi in the body shape and the much smaller size of the genital complex. Mazocraeoides fusiformes n. sp. differs from all the other species of the genus in the distribution of the clamps embracing only the posterior part of the testis and the genital complex consisting of one pair of needle-like lateral hooks and five pairs of median hooks. Mazocraeoides prashadi is redescribed to fill the gaps existing in the earlier description. Mazocraeoides dussumieri recorded earlier from South China Sea is reported for the first time from the Bay of Bengal. The validity of various species of Mazocraeoides is discussed and a key for the separation of valid species is provided. A host-parasite list is presented which gives details of the hosts, the geographic distribution and the validity status for each species. A partial 28S rDNA sequence was generated for M. dussumieri and deposited in GenBank.

Full text
Abstract:
Specimens of Hexostoma thynni (Delaroche, 1811) Rafinesque, 1815 were collected from their type-host, the bluefin tuna Thunnus thynnus, caught off Algeria, i.e. close to the type-locality, off Mallorca, which is also in the Mediterranean. The species is briefly redescribed and compared to previous descriptions, under the same name or as its synonym Plagiopeltis duplicata Diesing, 1858, to ascertain identity of specimens. The three genera within the Hexostomatidae (Hexostoma Rafinesque, 1815, Neohexostoma Price, 1961 and Homostoma Unnithan, 1965) are briefly discussed, with comments on the fragility of characters used to distinguish them. Using next-generation sequencing, the complete mitogenome and the cluster of ribosomal genes (SSU, LSU, ITS1, ITS2, 5.8S) were obtained. The mitogenome is 14,649 bp long and codes for 12 protein-coding genes, 2 ribosomal RNA genes and 22 transfer RNA genes; its size is similar to other mitogenomes obtained from polyopisthocotylean monogeneans. A phylogeny based on concatenated mitogenome protein-coding genes from nine species of polyopisthocotylean monogeneans produced a tree in which the Hexostomatidae H. thynni was associated with other Mazocraeidea, such as Chauhaneidae and Diclidophoridae. This invalidates the hypothesis of Boeger & Kritsky (1993) of Hexostomatidae as sister-group to the Mazocraeidea and suggests the demise of the suborder Hexostomatinea Boeger & Kritsky, 1993. We insist on the usefulness of depositing parts of specimens used for molecular analyses, prepared on permanent slides, in a curated collection.

Abstract:
The anatomy and behaviour of the oncomiracidia of Kuhnia scombri, K. sprostonae and Grubea cochlear, related mazocraeid monogeneans from the gill chamber of the mackerel, Scomber scombrus, caught off Plymouth are compared. K. sprostonae and G. cochlear are new records at Plymouth. The most important anatomical difference between these larvae is that those of Kuhnia spp. possess a pair of pigment-shielded eyes which are lacking in G. cochlear. The freshly hatched larvae of Kuhnia spp. are strongly photopositive but this response wanes after about 1 h in K. scombri and 1–5 h in K. sprostonae. No response to light was detected in larvae of G. cochlear. Most older larvae of Kuhnia spp. and of G. cochlear swim continuously upwards and downwards, even in ‘darkness’, indicating an alternation between positive and negative geotropism. The larvae of Kuhnia spp. possess angular cells (?) of unknown function close to the pharynx. The larvae of all three species contain prominent anterior glands and lipid droplets; the latter are depleted during their long free-swimming lives (up to 36 h in Kuhnia spp. at 13–14°C).

Abstract:
Sperm ultrastructure provides morphological characters useful for understanding phylogeny; no study was available for two basal branches of the Polyopisthocotylea, the Chimaericolidea and Diclybothriidea. We describe here spermiogenesis and sperm in Chimaericola leptogaster (Chimaericolidae) and Rajonchocotyle emarginata (Hexabothriidae), and sperm in Callorhynchocotyle callorhynchi (Hexabothriidae). Spermiogenesis in C. leptogaster and R. emarginata shows the usual pattern of most Polyopisthocotylea with typical zones of differentiation and proximo-distal fusion of the flagella. In all three species, the structure of the spermatozoon is biflagellate, with two incorporated trepaxonematan 9 + “1” axonemes and a posterior nucleus. However, unexpected structures were also seen. An alleged synapomorphy of the Polyopisthocotylea is the presence of a continuous row of longitudinal microtubules in the nuclear region. The sperm of C. leptogaster has a posterior part with a single axoneme, and the part with the nucleus is devoid of the continuous row of microtubules. The spermatozoon of R. emarginata has an anterior region with membrane ornamentation, and posterior lateral microtubules are absent. The spermatozoon of C. callorhynchi has transverse sections with only dorsal and ventral microtubules, and its posterior part shows flat sections containing a single axoneme and the nucleus. These findings have important implications for phylogeny and for the definition of synapomorphies in the Neodermata. We point out a series of discrepancies between actual data and interpretation of character states in the matrix of a phylogeny of the Monogenea. Our main conclusion is that the synapomorphy “lateral microtubules in the principal region of the spermatozoon” does not define the Polyopisthocotylea but is restricted to the Mazocraeidea.

Abstract:
ABSTRACT Members of the family Diclidophoridae are potentially dangerous species for the puffer fish aquaculture worldwide. They are parasitic polyopisthocotyleans, with a posterior haptor equipped with clamps for attachment to the host's surface, allowing the worm to resist the flow of water to maintain its position on gills. The anterior body of the worm is deformable, allows the worm to feed on blood sucked from fish gills. The present study is the first description of a Heterobothrium species from the gills of the tiger puffer Lagocephalus sceleratus (Tetraodontidae) from the coasts of the Arabian Gulf at Jubail, Saudi Arabia morphologically by light microscopy as well as by molecular analysis of the parasite partial 28S rRNA through multiple sequence alignments and phylogeny by maximum likelihood analysis which is provided for the first time for the described species. Seventeen tiger puffer fish were captured alive from marine water off Saudi Arabia; gills were separated and further examined for parasitic infection. Nine fish were found infected with a monogenean parasite which was robust, equipped by two buccal organs at the tapered anterior end; the posterior haptor was rectangular with four symmetrically arranged clamps, with no isthmus. Marginal hooks absent. Ovary elongated, U-shaped, testes numerous, irregularly shaped and extended from the posterior part of the ovary to the anterior margin of the haptor. Copulatory organ muscular, as a spherical cup armed with 12 to 15 genital hooks. The molecular analysis of the parasite 28s rRNA and phylogeny revealed a percentage of identities between 87.47-89.09%, with Diclidophoridae species within the monophyletic clade of Mazocraeidea where a maximum percentage of 89.09% were obtained for the morphologically different sister taxon H. okamotoi. The results obtained from molecular analysis are consistent with the conclusions drawn from morphological classification where that the parasite recorded was morphologically similar to H. lamothei which was not characterized by molecular analysis before. The recovered sequences were deposited into the GeneBank under accession number MT322610.

AbstractPolyopisthocotylean monogenean parasites of fishes are highly host specific and have been used as an appropriate model to study the host-parasite co-evolution. In the present study, eight monogeneans of the order Mazocraeidea were characterized by nuclear 28S rDNA sequences and their phylogenetic relationship with other polyopisthocotylean species was investigated. Neighbour-joining, maximum parsimony, maximum likelihood and Bayesian Inference methods were used for phylogenetic reconstruction. The topology sustained by high bootstrap was: (((Hexabothriidae (Mazocraeidae (Discocotylidae (Diplozoidae (Diclidophoridae (Plectanocotylidae (Heteromicrocotylidae (Microcotylidae (Heteraxinidae), (Thoracocotylidae, Gotocotylidae (Gastrocoylidae (Allodiscocotylidae: Protomicrocotylidae))). In addition, we have also developed DNA barcodes (COI sequences) for six species and the barcodes clearly discriminated all the species. The polytomy within Protomicrocotylidae family is resolved in this study for the first time and it appears that within this family, Bilaterocotyloides species are basal compared to Neomicrocotyle and Lethacotyle species while the latter is the more derived.

Abstract:
Abstract Background Diplozoidae are monogenean (Monogenea: Polyopisthocotylea) fish parasites characterised by a unique life history: two larvae permanently fuse into an X-shaped “Siamese” organism. Taxonomy and phylogeny of Diplozoidae and Polyopisthocotylea remain unresolved due to the unavailability of molecular markers with sufficiently high resolution. Mitogenomes may be a suitable candidate, but there are currently only 12 available for the Polyopisthocotylea (three for Diplozoidae). The only available study of diplozoid mitogenomes found unique base composition patterns and elevated evolution rates in comparison with other Monogenean mitogenomes. Methods To further explore their evolution and generate molecular data for evolutionary studies, we sequenced the complete mitogenomes of two Diplozoidae species, Paradiplozoon homoion and Paradiplozoon yarkandense, and conducted a number of comparative mitogenomic analyses with other polyopisthocotyleans. Results We found further evidence that mitogenomes of Diplozoidae evolve at a unique, elevated rate, which was reflected in their exceptionally long branches, large sizes, unique base composition, skews, and very low gene sequence similarity levels between the two newly sequenced species. They also exhibited remarkably large overlaps between some genes. Phylogenetic analysis of Polyopisthocotylea resolved all major taxa as monophyletic, and Mazocraeidea was split into two major clades: (Diplozoidae) + (all four remaining families: Diclidophoridae, Chauhaneidae, Mazocraeidae and Microcotylidae). It also provided further confirmation that the genus Paradiplozoon is paraphyletic and requires a taxonomic revision, so the two species may have to be renamed Indodiplozoon homoion and Diplozoon yarkandense comb. nov. Conclusions Although our findings indicate that mitogenomes may be a promising tool for resolving the phylogeny of Polyopisthocotylea, elevated evolutionary rates of Diplozoidae may cause phylogenetic artefacts, so future studies should pay caution to this problem. Furthermore, as the reason for their elevated evolution remains unknown, Diplozoidae are a remarkably interesting lineage for other types of evolutionary mitogenomic studies. Graphical Abstract

AbstractThis study determines the occurrence and molecular characterisation of Monogenea from three commercially important Australian fish: Australian sardine Sardinops sagax (Jenyns), Australian anchovy Engraulis australis (White), and eastern school whiting Sillago flindersi McKay. Earlier studies have provided only morphological species identification, whereas this study combines both morphological and molecular methods. A total of 247 fish across 3 species, sourced from the New South Wales and Victorian coasts, were examined for Monogenea. A total of 187 monogenean parasites were recovered from the gills. The overall prevalence, mean intensity, and mean abundance were 34%, 2.23, and 0.78, respectively. The parasites were initially classified morphologically as three species across two families. Family Mazocraeidae was represented by Mazocraes australis Timi et al. J Parasitol 85:28–32, 1999, and family Microcotylidae by Polylabris sillaginae (Woolcock, Parasitology 28:79–91, 1936) Dillon, Hargis, and Harrises, 1983 and P. australiensis Hayward, 1996. Molecular identification of parasites was conducted through sequencing of the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene. The fish hosts in the present study were also barcoded (mitochondrial cox1 gene) to confirm specific identities. There was no comparable cox1 sequence available in GenBank for the parasites found in the present study. However, the phylogenetic tree clustered the monogenean species identified in this study according to their familial groups of Mazocraeidae and Microcotylidae. The presence of M. australis on E. australis and S. sagax was confirmed in this study. Polylabris australiensis was only found on S. sagax but Si. flindersi was found to be a host for both Polylabris species. This study is the first to explore the mitochondrial cox1 genes of these three-monogenean species. These findings will serve as a foundation for future monogenean research in Australian waters and elsewhere.

Abstract:
Sphyraena ensis is distributed in the Eastern Pacific from Mexico to Chile, including the Galapagos Islands. Despite the wide distribution of this fish, knowledge of the parasitic fauna of S. ensis is restricted to only three monogenean species. The objective of this study was to record and describe two monogenean species of S. ensis in northern Peru. During a parasitological study from May to October 2019, monogeneans were collected from the gills of 138 specimens of S. ensis from Caleta de Zorritos, Contralmirante Villar Province, Tumbes, on the north coast of Peru. Helminths were stained in carmine acetic acid, dehydrated in ethyl alcohol, diaphanized in clove oil and mounted in Canada balsam. To observe the sclerotized structures, several specimens were placed in Hoyer’s medium. We identified the following monogeneans not previously reported in Peru: Pseudochauhanea mexicana and Scomberocotyle scomberomori. This is the first report of these two monogeneans in Peru, and the first report of P. mexicana in South America. Furthermore, S. ensis is reported as a new host of S. scomberomori.

Abstract:
In this study, 75 chub mackerels that were caught in the Canakkale Strait in Türkiye between October to December, 2019, were examined for the presence of parasites. The length and weight of all fish were measured and the external body area, oral cavity, nostrils, fins, and gills were examined. Gill samples were examined under a stereomicroscope and all suspicious findings were preserved in 99.99% ethanol. The mean length and weight of fish were 24.84±0.39cm and 146.01±7.16 gr, respectively. It was determined that the collected parasite is Grubea cochlear, a monogenic helminth belonging to the Mazocraeidea family. The chub mackerel, in which the specimen of G. cochlera was isolated among the gill filaments, was a female with a total length of 18.5 cm and a weight of 49.80 gr. This finding of Grubea cochlear isolated from the gills of chub mackerel is the first record of this species in this region.

Abstract:
ABSTRACT Fish, like all other species, can be impacted by a variety of environmental conditions, including parasitic infections. Although there are several parasitological researche on ectoparasitic monogeneans, few are published on those that infect sparid fish. Forty samples of Acanthopagrus bifasciatus were collected during this study from coastal regions along the Arabian Gulf (Saudi Arabia). Gills from all fish were isolated and examined to identify monogeneans. The parasites were studied morphologically using light microscopy. Overall prevalence and mean intensity were 20% and 9, respectively. Eight out of 40 (20%) fish samples were found to be naturally infected with a monogenetic species, namely, Bivagina pagrosomi (Murray, 1931) Dillon and Hargis, 1965 belonging to Microcotylidae (order Mazocraeidea). This parasite is characterized by the presence of haptor provided 43-47 clamps of microcotylid-type that deeply penetrated the gill lamellae and caused severe pathological impacts including hyperplasia, telangiectasis, and deformity of the respiratory epithelial cells Our finding indicates that this is the first report of A. bifasciatus being infected with B. pagrosomi from Saudi marine waters as well as the research of its deleterious effects on its host gills. More research is needed to confirm the parasite species’ taxonomic status at the molecular level.

ABSTRACT Fish is considered one of the nutritive protein sources affected by various parameters including parasitism. Monogeneans are an ectoparasitic species infecting fish’s skin, fins, and gills. During the present investigation, a total of 40 fish samples of the twobar seabream, Acanthopagrus bifasciatus (Perciformes: Sparidae) were collected from the coastal region along the Arabian Gulf (Saudi Arabia). The collected fish samples were dissected and examined for the presence of monogenetic parasites. The recovered parasite species were collected and identified by applying light microscopic examinations. Five out of 40 (12.5%) fish samples were found to be naturally infected with 2 monogenetic species belonging to two families within Polyopisthocotylea (order Mazocraeidea). They recorded two parasite species, namely, Pseudodiscocotyla opakapaka Yamaguti, 1965 and Kannaphallus raphidium Kritsky and Martin, 2023 belonging to families Discocotylidae and Heteraxinidae, respectively. Morphological and morphometric characterizations revealed some differences between the present species and others detected previously. The present findings of P. opakapaka and K. raphidium in A. bifasciatus (fish host) of the Arabian Gulf represent a new host and geographical record for these parasites. Furthermore, more studies are required to include the advanced molecular tools for these monogenetic species and their associated histopathological effects on the infection site.

AbstractThe metazoan parasite assemblage of the head of 30 specimens of the Atlantic chub mackerel (Scomber colias) from the western Mediterranean Sea was analysed. Eight species of parasites were found, four mazocraeid monogeneans: Grubea cochlear (prevalence = 10%), Kuhnia scombercolias (59%), K. scombri (52%), Pseudokuhnia minor (86%); three didymozoid trematodes: Nematobothrium cf. faciale (21%), N. filiforme (41%), N. scombri (7%); and one laerneopodid copepod: Clavelissa scombri (7%). Results were compared with previously published data from 14 localities of the eastern Mediterranean Sea and the Atlantic Ocean, using non-parametric univariate and multivariate analyses, and the whole parasite fauna of S. colias was compared with that of the congeners (S. australasicus, S. japonicus and S. scombrus). Parasites showed to reflect the biogeographical and phylogenetic history of host. From a methodological point of view, the use of both non-parametric univariate and multivariate techniques proved to be effective tools to detect dissimilarities between parasite assemblages.

Abstract:
AbstractMonogeneans are highly host‐specific parasites infecting marine and freshwater fish. However, little information is available about the parasitic taxa within Heteraxinidae. An integrative study was performed to understand the taxonomic status of an unconfirmed heteraxinid marine species parasitizing the gill region of Acanthopagrus bifasciatus (Sparidae) from the Arabian Gulf (Saudi Arabia). Based on the morphological study, this parasite has all the generic features of the genus Kannaphallus (Heteraxinidae, Mazocraeidea). Distinct criteria that discriminated this species from other taxa of the same genus are the presence of genital spines (26–29), a short sclerotized duct in the male copulatory organ, the number of testes (mean 40, range 30–50), and clamps in the haptoral structure (45–50 in a long row and 19–22 in a short row). DNA of parasite species reported in the present study was amplified and sequenced for the nuclear large subunit of the ribosomal RNA (28S rRNA) gene and the mitochondrial cytochrome c oxidase subunit I (COI) gene. Results indicate that sequences obtained from both genes are unique and different from related sequences from the genus Kannaphallus. Morphological as well as molecular data indicate that our specimens are from a new species, and the name Kannaphallus acanthopagrusi n. sp. is suggested. This is the first report of a heteraxinid parasitizing marine sparid fish from Saudi Arabia, with unique morphological and molecular features.
