  • Description and molecular characteristics of Morishitium polonicum malayense Urabe, Nor Hashim & Uni, n. subsp. (Trematoda: Cyclocoelidae) from the Asian glossy starling, Aplonis panayensis strigata (Passeriformes: Sturnidae) in Peninsular Malaysia.

    [Abstract]

    We describe Morishitium polonicum malayense n. subsp. from Asian glossy starlings (Aplonis panayensis strigata) (Horsfield, 1821) (Passeriformis: Sturnidae) caught in Malaysia. The trematodes had parasitized the air sacs and the thoracic and body cavities of 40 out of 67 (59.7%) birds examined. The specimens each had an oral sucker, a postpharyngeal genital pore, and tandem testes, but lacked a ventral sucker. The morphological characteristics of our specimens were similar to those of M. polonicum polonicum (Machalska, 1980) from Poland. However, the anterior extremity of vitelline follicles of the present specimens sometimes extended to the level of pharynx. The oral sucker width, oral sucker width/pharynx width ratio, and intertesticular space metrics differed from those of M. p. polonicum. The maximum-likelihood trees based on the cytochrome c oxidase subunit I (COI) and the internal transcribed spacer 2 (ITS2) sequences indicated that the species from the present study formed a sister group with M. p. polonicum from the Czech Republic. The p-distances of COI and ITS2 sequences between the present specimens and M. p. polonicum from the Czech Republic were 6.9–7.5% and 0.6%, respectively. These genetic divergences indicate the border for intra- or interspecific variation of digeneans. The definitive host species and geographical distribution of the current specimens were distinct from those of M. p. polonicum from Europe. We thus concluded that the present specimens are ranked as a new subspecies of M. polonicum, namely M. polonicum malayense n. subsp.

  • Do atypical 15N and 13C enrichment in parasites result from isotope ratio variation of host tissues they are infected?

    [Abstract]

    Contrary to a general rule of stable isotope trophic discrimination, parasites show great variation in isotope discrimination from their host muscle tissues. One of the possible mechanisms is that isotopic variation among host tissues may cause apparent deviation from the actual isotope discrimination between a parasite and a given host tissue consumed by the parasite. To test this possibility, we measured δ15N and δ13C for some fish parasites and a variety of their host tissues to estimate their actual trophic discrimination factors (Δ). All of the trematodes investigated showed positive Δ15Ν values and nearly zero Δ13C values, which are comparable to those of free-living consumers. Cestodes and nematodes showed great variations in their Δ15Ν and Δ13C values when they were compared to a particular tissue/mucus of their infection site. Acanthocephalans showed negative Δ15Ν and Δ13C values in comparison with host intestinal mucus, and a crustacean had δ values similar to those of host blood. Even in parasites infected to intestine, Δ15Ν and Δ13C values varied among higher taxa. These results suggested that atypical 15N and 13C enrichment of parasites is not caused by the variation in δ values among host tissues, but possibly by metabolic processes unique to each parasite taxon.

    [Abstract]

    We performed the first host-parasite survey of the Philippine crocodile, Crocodylus mindorensis, a critically endangered species for which ecological information is lacking. We collected by gastric lavage samples of the stomach contents of crocodiles (n = 10) residing at the Palawan Wildlife Rescue and Conservation Center in Puerto Princesa, Palawan, Philippines. The only parasite detected was an acanthocephalan, which was identified as Neorhadinorhynchus nudus (n = 68), a parasite typically found in the marine fish species consumed by three crocodile individuals. Given the known hosts of N. nudus, its parasitism of C. mindorensis in captivity is likely established by consumption of marine fish. Our findings have implications for the conservation management of C. mindorensis, particularly in terms of preventing introduction of parasites that could lead to development of infectious disease or alter the fitness of captive animals.

  • Redescription and supplementary molecular characteristics of Aspidogaster ijimai Kawamura, 1915 (Trematoda, Aspidogastrea, Aspidogastridae), a parasite of Cyprinus carpio Linnaeus, 1758 s. lato (Actinopterygii) and freshwater bivalves in East Asia

    [Abstract]

    A detailed morphological description and ribosomal DNA (rDNA) sequence molecular data for Aspidogaster ijimai from Japan are provided. Morphological analysis, including a description of the cirrus-sac, indicate the conspecificity of Japanese and continental East Asian A. ijimai specimens. Analysis of ITS1-5.8S-ITS2 rDNA sequences of Japanese, Chinese and Russian specimens confirmed the morphological results. Phylogenetic analysis using ITS rDNA sequences confirmed that A. ijimai is a sister species for Aspidogaster chongqingensis. Median-joining network analysis showed an initial molecular differentiation step of Russian specimens from group of Japanese-Chinese samples. Our 28S rDNA results based on maximum likelihood (ML) and Bayesian (BI) phylogenetic analyses indicated well-supported monophyly of the Aspidogaster conchicola + A. ijimai group, a finding that indicates that these species are congeneric. At the same time, our data demonstrated that the genus Lobatostoma is paraphyletic and the family Aspidogastridae is polyphyletic, results that confirm previous studies.

    [Abstract]

    © Cambridge University Press 2018. In the present paper, the phylogenetic relationships between genera, subfamilies and families of the Hemiuroidea are explored. Twelve new sequences of 28 rDNA and data taken from GenBank (NSBI) on 43 species affiliated to 34 genera were included in the analysis. Most of the hemiuroidean trematodes form two highly supported clades (A and B), which are sister groups to each other. Hemipera manteri joined with Gonocerca spp. with moderate statistical support. This clade is basal relative to the clades A and B. Dilade A is polytomic and contains representatives of the families Accacoeliidae, Syncoeliidae, Didymozoidae, Hirudinellidae and Sclerodistomidae, and derogenid subfamilies Derogeninae and Halipeginae. At the same time, the Syncoeliidae, Hirudinellidae and Accacoeliidae form a well-supported monophyletic group. The phylogenetic relationship between Derogeninae and Halipeginae is poorly resolved. Dilade B unites the isoparorchiid, bunocotylid, lecithasterid and hemiurid trematodes. Our data re-establishes the family Bunocotylidae, which consists of two subfamilies, Opisthadeninae and Bunocotylinae, and the Machidatrema chilostoma + Hysterolecithoides frontilatus group. The Bunocotylidae is the sister group to the Hemiuridae + Lecithasteridae group and the Isoparorchiidae is a basal relative to the representatives of these three hemiuroid families.
