Morphological and molecular characterization of Hysterothylacium larval morphotypes (Nematoda: Raphidascarididae) infecting edible marine fish in the Black Sea

Parasitology Research, 2023
The morphological and molecular identification of Hysterothylacium larval morphotypes in the Black Sea remains unresolved and incomplete. The aim of current study was to provide a detailed morphological identification with rDNA whole ITS (ITS‒1, 5.8S subunit, ITS‒2) and mtDNA cox2 sequences data of Hysterothylacium larval morphotypes infecting four ...

Morphological and molecular identification of Hysterothylacium larvae (Nematoda: Raphidascarididae) in marine fish from Tunisian Mediterranean coasts

Parasitology Research, 2020
The taxonomy of Hysterothylacium genus in Mediterranean waters remains incomplete and unresolved. The aim of the current study was to investigate the morphological and molecular identification of selected species of Hysterothylacium larvae in marine fish from the Tunisian Mediterranean coasts. A total of 192 marine fish samples were examined. In total,

Morphological and molecular characterization of selected species ofHysterothylacium(Nematoda: Raphidascarididae) from marine fish in Iraqi waters

Journal of Helminthology, 2017
AbstractHysterothylaciumspecies are perhaps the most abundant and diverse group of marine ascaridoids; however, their life cycle and specific identification in larval stages in many parts of the world, particularly in Iraqi marine waters, have not been completely understood.

Hysterothylacium fabri(Nematoda: Raphidascarididae) inMullus surmuletus(Perciformes: Mullidae) andUranoscopus scaber(Perciformes: Uranoscopidae) from the Mediterranean

Journal of Parasitology, 2018
Raphidascarididae are among the most abundant and widespread parasitic nematodes in the marine environment. The life-cycle of most raphidascaridid species is poorly known and information about their distribution and host range is lacking in many geographical areas, as is the taxonomy of several species.

First description of aRaphidascarisspecies (Nematoda: Raphidascarididae) in a mudskipperApocryptes bato(Actinopterygii: Gobiidae) from West Bengal, India

Journal of Helminthology, 2021
AbstractA new nematode species,Raphidascaris mundeswariensisn. sp. (Raphidascarididae), is described from male and female specimens found in the intestines of the mudskipperApocryptes bato(Hamilton, 1822) (Gobiidae) from the Mundeswari River of West Bengal, India. This species is distinguished from its congeners by 214–255-μm-long spicules, 14 pairs of

Morphometric and molecular descriptions of three new species of Hysterothylacium (Nematoda: Raphidascarididae) from Australian marine fish

Journal of Helminthology, 2016
AbstractThree new species of Hysterothylacium Ward & Magath, 1917, including H. australe, H. kajikiae and H. brucei, from Australian marine fish are described and illustrated by light microscopy followed by genetic characterization of their first and second internal transcribed spacers (ITS-1 and ITS-2, respectively).

Goezia nankingensis Hsü, 1933 (Nematoda: Raphidascarididae) from the critically endangered Chinese paddlefish Psephurus gladius (Martens) (Acipenseriformes: Polyodontidae)

Systematic Parasitology, 2012
Goeziine nematodes identified as Goezia nankingensis Hsü, 1933 were collected from the Chinese paddlefish Psephurus gladius (Martens) (Acipenseriformes: Polyodontidae), a critically endangered freshwater fish, from the Yangtze River in China. Their examination, using light microscopy and, for the first time, scanning electron microscopy, revealed some ...

The morphology and genetic characterization of Iheringascaris goai n. sp. (Nematoda: Raphidascarididae) from the intestine of the silver whiting and spotted catfish off the central west coast of India

Journal of Helminthology, 2011
AbstractIn this study a new species of nematode, Iheringascaris goai n. sp., is reported from two fish hosts, including silver whiting, Sillago sihama, and spotted catfish, Arius maculatus, caught off the Central West Coast of India at Goa. The new species can be differentiated morphologically from I. inquies, the most closely related species collected

Morphological and genetic characterization of Hysterothylacium Ward & Magath, 1917 (Nematoda: Raphidascarididae) larvae in horse mackerel, blue whiting and anchovy from Spanish Atlantic and Mediterranean waters

Journal of Fish Diseases, 2018
AbstractThe presence of zoonotic Hysterothylacium larvae in fish from Spanish Atlantic and Mediterranean waters, which can cause economic losses for commercial fisheries, has been reported in several studies; however, little is known about species identity in this region.

Morphological variability, ultrastructure and molecular characterisation of Hysterothylacium reliquens (Norris & Overstreet, 1975) (Nematoda: Raphidascarididae) from the oriental sole Brachirus orientalis (Bloch & Schneider) (Pleuronectiformes: Soleidae)

Parasitology International, 2017
Hysterothylacium reliquens (Norris & Overstreet, 1975), a common ascaridoid nematode parasitic in the marine fishes in the Indian and Atlantic Oceans, has been reported to exhibit remarkable morphological variability in the lengths of body, oesophagus and spicules, and the number and arrangement of postcloacal papillae. In order to determine whether H.
