Anisakid Nematodes

The present study provides a new insight into valuable information on the diverse structure of the Anisakid population and discusses the limited species richness in the Nemipterus japonicus (Bloch,1791) (Perciformes, Nemiperidae). The fishing area consists of various locations in the Arabian Gulf (29°58 0 33 00 N48°28 0 20 E). A total of 315 marine fish were examined, (n=287) were infected. Larval stages (n= 763) encysted within the mesenteries peritoneum and viscera of fish organs were isolated, with a prevalence of 91.11% of infection and, the intensity was 2.65. Molecular analysis was carried out on thirty individuals who have examined the morphology and showed some appearance differences, by amplifying internal transcribed spacers ITS and ITS-1 of nuclear rDNA (rDNA) by PCR using the primer sets NC5/NC2 and SS1/NC13R of thirteen DNA products. Evolutionary analyses were conducted in MEGA X. based on the identity percentage in the GenBank database showed that they belong to anisakid nematodes, in particular, they belong to eleven distinct taxa within the Hysterothylacium Ward & Magath, 1917 (Rhabditida, Raphidascarididae) and one identified species H. amoyense (Hsü, 1933) Deardorff & Overstreet, 1980. The current study records eleven species that belong to a genus of Hysterothylacium; some of the alignment of sequences polymorphisms reveals new different individuals of larvae species that may be adopted as new species if their adult stage is detected, and N. japonicus fish considered as a new host record. The current study provides some insights on the systematic taxonomy of these parasites, in addition, it supports similar studies that have been published elsewhere.

AbstractSix species of Bucephalidae are reported: Subfamily Bucephalinae: Bucephalus sphyraenae Yamaguti, 1952 from Sphyraena obtusata and S. chrysotaenia (Sphyraenidae) (new host records); Bucephalus margaritae Ozaki and Ishibashi, 1934 from Atropus atropos, Scomberoides commersonianus, Carangoides malabaricus (Carangidae), Gerres filamentosus (Gerreidae) (new host record) and Sphyraena jello (new host record); Rhipidocotyle pseudorhombi n. sp. from Pseudorhombus arsius is characterized by and differs from its congeners by several characteristics including an elongate body, a rhynchus with 7 thin papillae, a long tuular caecum extending posteriorly to the ovarian level, goads in the posterior half of the body, and contiguous testes not separated by uterine coils. More specifically it differs from R. heptathelata and R. septapapillata by having a long cirrus sac relative to body length, tandem and more anterior testes. Subfamily Prosorhynchinae: Prosorhynchus pacificus Manter, 1940 from Epinephelus tauvina (Serranidae) and Gnathonodon speciosus (Carangidae) (new host record); P. epinepheli Yamaguti, 1939 from Epinephelus areolatus; P. manteri Srivastava, 1938 from Trichiurus lepturus (Trichiuridae). All species, except Prosorhynchus epinepheli represent new records from the Arabian Gulf.

Contracaecum Osculatum

From Phoca vitulina richardi the following parasites are recorded: Corynosoma strumosum (Acanthocephala); Terranova decipiens and Contracaecum osculatum (Nematoda); Halarachne sp. (Acarina); Echinophthirius horridus (Anoplura). From Eumetopias jubata are recorded Diphyllobothrium pacificum, Diplogonoporus tetrapterus and Abothrium gadi (Cestoda); T. decipiens, C. osculatum and Parafilaroides sp. (Nematoda); Corynosoma villosum (Acanthocephala); Orthohalarachne diminuata (Acarina): Antarctophthirus microchir (Anoplura). E. jubata is probably not a true host of A. gadi, the parasite apparently being introduced by ingestion of infected fishes of the family Gadidae, the normal definitive hosts. Notes on host and geographical distribution, nomenclature and morphology of the parasites are included. Diphyllobothrium pacificum is a new combination for Adenocephalus pacificus. E. jubata is a new host record for D. pacificum, D. tetrapterus and O. diminuata. Several new geographical records are reported. The occurrence of larval stages of T. decipiens and C. strumosum in fishes is noted.

Species of Symphrasinae (Neuroptera: Mantispidae) are ectoparasitoids of larvae and pupae of holometabolous insects, primarily of Hymenoptera in their larval stages. Herein we present the third case of an association between the mantidfly genus Anchieta Navás, 1909 with the order Hymenoptera. The hymenopteran species attacked by the as of yet undescribed species of Anchieta is Montezumia dimidiata Saussure, 1852 (Vespidae: Eumeninae), a predacious wasp that constructs mud nests. The association was observed in Peruvian Amazonia (near Tarapoto, San Martín), after rearing the mantidflies from a wasp nest. The biology and mimicry pattern with stingless bees of the reared Anchieta species is discussed.

The Difference

An investigation of the digenetic trematodes of anurans from Agbede, a location in the derived savanna biotope in Edo state,Nigeria was conducted from August, 2007 to July, 2008. Anuran hosts examined included Sclerophrys maculata, S.regularis, Ptychadena pumilio, P. bibroni, P. oxyrhynchus, Hoplobatrachus occipitalis and Hylarana galamensis. Theanurans were collected using the Visual Acoustic Encounter Survey (VAES) method, dissected and examined for trematodeinfections. A total of 267 anurans were examined of which 33 were infected with an overall prevalence of 12.36%. Seasonalprevalence was 14.88% for the wet season and 8.08% for dry season. The difference in prevalence values was not statisticallysignificant (p >0.05). Four digenetic trematodes, namely, Mesocoelium monodi, an unidentified Mesocoelium sp.,Haematoloechus exoterorchis and an unidentified Haematoloechus sp. Haematoloechus exoterorchis was recovered from H.occipitalis while the unidentified Haematoloechus sp. infected H. occipitalis and Sclerophrys maculata. Mesocoeliummonodi infected only Sclerophrys maculata while the unidentified Mesocoelium sp. was a generalist, infecting five anuranhosts. Sclerophrys maculata is thus a new host record for the genus Haematoloechus in Nigeria. In conclusion, this studyrevealed a low trematode diversity in the anurans of the savanna-mosaic at Agbede. However, anurans from this locationharboured two new trematodes: an unidentified Mesocoelium sp and a Haematolechus sp. Sclerophrys maculata as a newhost record for the genus Haematoloechus in Nigeria. More specimens of the Haematoloechus sp. are needed for themorphological description and molecular characterization of the parasite, to establish its relationship with the cogener inH.occipitalis.

Abstract Morphological Redescription and Molecular Characterization of Dactylogyrus labei (Monogenea, Dactylogyridae) from Catla catla: a New Host Record in India. Chiary, H. R., Chaudhary, A., Singh, H. S. - Dactylogyrus labei Musselius et Gusev, 1976 (atypical form) specimens were collected from host Catla catla from the river Brahmaputra, Guwahati, Assam, India. The Dactylogyrus samples were examined by morphological and molecular methods. This parasite was originally described from Labeo rohita from fish farm Kalyani, West Bengal, India, but the morphological study of sclerotized parts showed the existence of D. labei on Catla catla. This is the first record of D. labei from Catla catla in India.

Background: Heteraxinoides atlanticus Gayevskaya et Kovaleva (1979) is described from the locality of Arabian Sea, India. This monogenean species is first time reported from India, infesting the gills of Nemipterus japonicus (Bloch). The present study redescribes H. atlanticus and its phylogenetic status using morphometric and molecular tools. Methods: A total of 35 parasites were collected from the 234 specimens of Nemipterus japonicus at Mumbai, India. The temporary and permanent mounts were prepared for the morphometric analyses of H. atlanticus. For PCR, the genomic DNA was isolated from the parasites using primers for 18S rDNA, 28S rDNA and mtCOI gene. The obtained DNA sequences were subjected to different bioinformatics softwares (BLASTn, Clustal Omega and MEGA) for phlyogenetic analyses.Result: Phylogenetic analyses with the help of partial 18S and 28S rDNA sequences of H. atlanticus and other available sequences of heteraxinids provided the better understanding of relationship in the family Heteraxinidae. Another species, H. karachiensis Hadi and Bilqees (2014) showed similar morphological features such as number of clamps and structure of genital atrium to H. atlanticus except few minor differences, so it must be considered as synonym of H. atlanticus and placed into Heteraxinidae instead of Axinidae.

Description and some ecological aspects of two species of Eudactylina (E. rhinabati and E. turgipes) were found parasitic on two specimens of Glaucostegus granulatus and seven of Gymnura poecilura during the period from January 2011 till June 2012 from the north west of the Arabian Gulf (Latitudes 48° 44? to 48° 46?; longitude 29° 46? to 29° 47?). The prevalence of infection and the mean intensity of infection of E. rhinabati and E. turgipes was 40 %, 4.5 and 28.5, 2 respectively. The present finding of E. rhinobati on the gills of G. granulatus represents its first record in fishes of the Arabian Gulf, and its second occurrence in the World, while the finding of E. turgipes  on the gills of G. poecilura in the present study represents a new host record and a new geographical distribution .

Recent examinations of anisakid nematodes (Anisakidae) from marine fishes off New Caledonia, collected in the years 2003–2008, revealed the presence of the following five new species of Raphidascaris Railliet et Henry, 1915, all belonging to the subgenus Ichthyascaris Wu, 1949: Raphidascaris (Ichthyascaris) spinicauda n. sp. from the redbelly yellowtail fusilier Caesio cuning (Caesionidae, Perciformes); Raphidascaris (Ichthyascaris) fasciati n. sp. from the blacktip grouper Epinephelus fasciatus (Serranidae, Perciformes); Raphidascaris (Ichthyascaris) nudicauda n. sp. from the brushtooth lizardfish Saurida undosquamis (Synodontidae, Aulopiformes); Raphidascaris (Ichthyascaris) euani n. sp. from the Japanese large-eye bream Gymnocranius euanus (Lethrinidae, Perciformes); and Raphidascaris (Ichthyascaris) elopsis n. sp. from the Hawaiian ladyfish Elops hawaiensis (Elopidae, Elopiformes). An additional two congeneric species, R. (I.) etelidis Moravec et Justine, 2012 and R. (I.) sillagoides (Bruce, 1990) were found in the deep-water red snapper Etelis carbunculus (new host record) and the deepwater longtail red snapper Etelis coruscans (both Lutjanidae, Perciformes), and the silver sillago Sillago sihama (Sillaginidae, Perciformes) (new host and geographical records), respectively. Two unidentified congeneric species, Raphidascaris (Ichthyascaris) sp. 1 from the trumpet emperor Lethrinus miniatus (Lethrinidae, Perciformes) and Raphidascaris (Ichthyascaris) sp. 2 from the white-spotted puffer Arothron hispidus (Tetraodontidae, Tetraodontiformes) were recorded. Moreover, two species of Hysterothylacium Ward et Magath, 1917, H. alatum Moravec et Justine, 2015 and H. epinepheli (Yamaguti, 1941), were found in the leopard coralgrouper Plectropomus leopardus (type host) and the highfin grouper Epinephelus maculatus (new host) (both Serranidae, Perciformes), respectively. This is the second finding of H. epinepheli since its original description in Japan 79 years ago. Most species are described based on light and electron microscopical studies.
