Seven helminth species were found: six cestodes (Anomotaenia tringae, Eurycestus avoceti, Branchiopodataenia gvozdevi, Confluaria podicipina, Fimbriarioides tadornae, Hymenolepis s.l. stellorae) and one unidentified acuariid nematode (Acuariidae gen. sp.).

Additionally, partial sequences of the 18S rDNA gene as well as the mitochondrial cytochrome c oxidase subunit 1 (cox1) and nicotinamide adenine dinucleotide dehydrogenase subunit 1 (nad1) genes were obtained for varying numbers of cestode and nematode isolates for the first time.

This study aimed to clone, express the 22.6-kDa tegument protein of S. spindale (rSs22.6kDa) and to utilise it in a dot enzyme-linked immunosorbent assay for serodiagnosis. RNA was extracted from adult worms recovered from the mesenteries of slaughtered cattle to amplify the gene encoding the 22.6-kDa protein. In silico analysis revealed the protein's secondary structure, consisting of 190 amino acids forming alpha helices (47.89%), extended strands (17.37%), beta turns (8.95%), and random coils (25.79%), with α helices and β sheets in the tertiary structure. Two conserved domains were noted: an EF-hand domain at the N-terminus and a dynein light-chain domain at the C-terminus. Phylogenetic studies positioned the S. spindale sequence as a sister clade to Schistosoma haematobium and Schistosoma bovis. The gene was cloned into a pJET vector and transformed into Escherichia coli Top 10 cells, with expression achieved using a pET28b vector, BL21 E. coli cells, and induction with 0.6 mM isopropyl-β-d-thiogalactopyranoside.

Recently, specimens of digeneans were collected from two distinct geographical locations: the Paraná River basin (Misiones province) and the Río de la Plata basin (Buenos Aires province). These specimens were found parasitizing two different fish species: Bryconamericus sylvicola and Bryconamericus iheringi. Sequences of the 28S and COI genes were obtained for both digeneans from the two collection sites and hosts. The morphological study, combined with genetic sequences, confirmed their assignment to the genus Saccocoelioides. The COI and 28S gene sequences obtained from specimens at both collection sites exhibited genetic distances of 0.13% and 3.41%, respectively, indicating that these Saccocoelioides specimens represent a single species. The comprehensive taxonomic study of the newly collected specimens, along with an examination of the type material of S. bacilliformis and S. octavus, allows us to confirm the validity of both species. Argentina is home to more than 550 species of freshwater fauna, and it is likely that new species of Saccocoelioides remain to be discovered in underexplored regions of the basin, such as the Uruguay, Pilcomayo and Bermejo rivers.","PeriodicalId":15928,"journal":{"name":"Journal of Helminthology","volume":"98 ","pages":"e85"},"PeriodicalIF":1.3,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142800746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The indiscriminate use of anthelmintics (i.e., benzimidazole class, BZ) to control infections has led to the reduction of drug efficacy in H. contortus populations worldwide. Resistance to BZ is associated with high frequencies of single nucleotide polymorphisms at F200Y, F167Y, and E198A positions of the β-tubulin isotype 1 gene. This study aimed to determine the frequency of single nucleotide polymorphisms associated with BZ resistance in H. contortus from 18 farms (545 sheep and 124 goats) in Paraná, Southern Brazil. Health management practices were identified as risk factors from individual farms. Genomic DNA was extracted from 20,000 larvae/farm and used in quantitative polymerase chain reaction assays for the three mutations. We ran a correlation analysis between flock health and quantitative polymerase chain reaction data. H. contortus was the most prevalent parasite in 67% (12/18) of the farms. Resistant allele frequencies were detected for F200Y (var. 46.4 to 72.0%) and F167Y (var. 15.7 to 23.8%). Only (100.0%) susceptible alleles were detected for the E198A. High treatment frequency (15/18), visual weight estimations for anthelmintic dose (15/18), no integration with other farm practices (14/18), treatment of all animals (14/18), and no quarantine period for newly acquired animals (10/18) were considered the most critical risk factors associated with BZ resistance.

Acanthocephalus anguillae, a widespread parasite of European freshwater fishes and isopod Asellus aquaticus, was recently discovered also in Postojna-Planina Cave System (Slovenia) parasitising olms (Proteus anguinus) and cave populations of A. aquaticus. This setting offers a unique opportunity to investigate potential fine-tuning of parasitic manipulations to the specifics of the highly divergent subterranean environment where some common phenotypic alterations lose functionality, but others might gain it. We measured three behavioural traits: movement activity, shelter-seeking, and response to light of infested and uninfested isopods from surface and cave populations. All behaviours were quantified from 1-h video-recordings via video-tracking isopod's movement in empty or custom modified (half-sheltered/half-illuminated) Petri dishes. Infested isopods of both populations spent significantly less time sheltering and were significantly less photophobic than uninfested ones, whereas the activity of isopods was not altered. However, we observed almost no cave-specific responses upon infestation in the two altered behaviours. It seems phenotypic alterations are not particularly fine-tuned to the subterranean environment and its hosts, and likely still reflect the parasite's surface origin.","PeriodicalId":15928,"journal":{"name":"Journal of Helminthology","volume":"98 ","pages":"e84"},"PeriodicalIF":1.3,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142801139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
