Freshwater fish in Bangladesh frequently serve as hosts for different clinostomid species. During the metacercaria stage, the digenetic trematode Euclinostomum heterostomum exhibits a specific preference for Channidae species, where it undergoes encystment within the liver, kidneys, and muscles of these hosts. The study aimed to identify E. heterostomum in Channa punctata through combined morphological and molecular analysis. Light and scanning electron microscopy were conducted to investigate the morphological characteristics of the species. The histological examination of the infected liver tissue revealed the presence of encysted flukes, inflammatory leukocyte infiltrates, and degeneration and loosening of hepatic tissue. In molecular analysis, the generated internal transcribed spacer 1 (ITS1), 5.8S ribosomal DNA and ITS2 regions sequence (GenBank accession no: OR591452) of 830 bp showed 100% identity with Euclinostomum heterostomum identified in India (MT785786). The phylogenetic reconstruction provided substantial evidence of genetic similarities (0–1% genetic distance) among different isolates of the genus Euclinostomum, suggesting that there is a shared heritage.","PeriodicalId":54436,"journal":{"name":"Systematic Parasitology","volume":"55 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142265761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

He referred to it seven times as L. zetta in the main text, but also five times as L. zeta in the figure legends. This nominal species is currently assigned to the genus Guerrerostrongylus Sutton and Durette-Desset, 1991. The complete bibliography referring to this species from 1937 to date comprises only 22 works. Although the spelling 'zetta' has prevailed since 2011, the correct original spelling of its specific name remains unsettled. Acting as First Revisers under Articles 24.2.3 and 32.2.1 of the International Code of Zoological Nomenclature, we hereby choose 'zeta' as the correct original spelling of the specific name of this nematode, thus rendering 'zetta' an unavailable incorrect spelling. In making this choice, we have taken into account Travassos' obvious intention to name the species after the sixth letter of the Greek alphabet and the longer use of the spelling 'zeta' in the relevant literature, especially in those works in which 'zeta' (never 'zetta') was first combined with other generic names. We believe that standardizing the use of the spelling 'zeta' as the correct original spelling is the best way to stabilize this name.","PeriodicalId":54436,"journal":{"name":"Systematic Parasitology","volume":"101 5","pages":"59"},"PeriodicalIF":1.0,"publicationDate":"2024-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142047536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of these 54 species, 36 were found to be infected by metacestodes. Metacestodes were characterised by morphological and molecular data (the D1-D3 region of the 28S rDNA gene); these data were analysed in parallel to inform larval type allocation. Metacestodes collected represented eight morphological types, seven previously reported (Types I, II, IV, V, VI, VII, and X) and one novel type (Type XVI). Phylogenetic analyses were conducted to genetically match larval types to adult cestodes. Six of the eight larval types found were matched to adult forms: Type I metacestodes matched species of Phoreiobothrium Linton, 1889 (Onchobothriidae); Type II metacestodes matched species of Acanthobothrium van Beneden, 1849 (Onchobothriidae); Type IV metacestodes matched species of Scyphophyllidium Woodland, 1927 and Alexandercestus Ruhnke & Workman, 2013 (Phyllobothriidae); Type VI metacestodes matched species of Anthobothrium van Beneden, 1850 (Tetraphyllidea incertae sedis); Type X metacestodes matched species of Ambitalveolus Caira & Jensen, 2022 (Tetraphyllidea incertae sedis); and Type XVI metacestodes matched species of Platybothrium Linton, 1890 (Onchobothriidae). Based on phylogenetic topology, Type V metacestodes are inferred to match Pedibothrium Linton, 1909 (Balanobothriidae) and Type VII metacestodes are inferred to match Spongiobothrium Linton, 1889 (Rhinebothriidae). These findings support and extend the unified morphological type system proposed previously, but suggest that morphological types will ultimately be informative to identify metacestodes to a group of related genera rather than any distinct genus.","PeriodicalId":54436,"journal":{"name":"Systematic Parasitology","volume":"101 5","pages":"57"},"PeriodicalIF":1.0,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11338972/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142019601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Blakerius gen. nov. diverges from the other herpyllobiid genera by its possession of 1) a chalice-shaped ectosoma with several protuberances along the posterior margin and a long cylindrical shaft with a hyaline coating and integumental sculpturing, a short stalk with a small, anteriorly placed sclerotized ring, 2) a relatively large, discoid-shaped endosoma with digitiform process, and 3) attached male copepodids with 3-segmented antennules, containing limbless sac-like males.

Herein, we describe a novel Cytauxzoon species infecting an asymptomatic little-spotted-cat (Leopardus tigrinus) based on morphological, histopathological, and molecular analyses. The animal was attended presenting a history of a run-over with multiple traumas. Although the little-spotted-cat was stabilized, he died a few days later. Ring-shaped merozoites within erythrocytes were found on blood smears and in the abdominal effusion. In addition, schizonts were observed in histiocytes in the liver. Phylogenetic analyses based on both near-complete 18S rRNA and cytb genes positioned the obtained sequences in a unique clade, albeit closely related to Cytauxzoon felis from the USA. Genetic divergences ranging from 0.004 and 0.067-0.068 were found between the near-complete 18S rRNA and cytb sequences of Cytauxzoon sp. detected in the little-spotted-cat and C. felis, respectively.
