Molecular analyses of several genetic markers have classified <i>G. duodenalis</i> into eight assemblages (A to H) exhibiting different host specificities. Assemblages A and B have zoonotic potential and infect a broad range of hosts. The European hedgehog (<i>Erinaceus europaeus</i>) is one of the wild species well-adapted to live in close proximity to humans. Therefore, surveying potential zoonotic parasites harbored by hedgehogs can also be of public health concern, particularly in urban settings with high animal densities.</p><h3>Recent findings</h3><p>Coproparasitological examinations are routinely conducted on hedgehogs admitted to WildUmbria Wildlife Rescue Center. <i>Giardia duodenalis</i> cysts were found in the fecal flotation of a hedgehog and were further tested using a direct immunofluorescent assay and PCR-RFLP molecular analysis of the <i>β</i>-giardin gene for assemblage and sub-assemblage characterization. The RFLP protocol attributed the samples to the AI-like zoonotic assemblage. Additionally, trophozoites attached to the intestinal mucosa of the small intestine were detected via histological techniques.</p><h3>Summary</h3><p>Although <i>G. duodenalis</i> has been detected in hedgehogs from several countries, it was never before reported in Italian hedgehogs.

The half-maximal inhibitory concentration (IC50) values for CNP against protoscoleces ranged from 39.9 to 341.3 µg/mL. Caspase-3 gene expression in the PS treated with CNP at 1/3 IC50, ½ IC50, and IC50 was 1.79-, 3.11-, and 5.39-fold change (<i>p</i> &lt; 0.001). Upon administration of CNP, particularly at doses of 80 mg/kg, a significant decrease (<i>p</i> &lt; 0.001) in hydatid cysts’ quantity, size, and weight was evident. CNP treatment caused a notable reduction in oxidative stress markers and inflammatory cytokines and increased the gene expression of antioxidant enzymes (<i>p</i> &lt; 0.001), whereas it modulated the serum levels of liver function parameters.</p><h3>Conclusion</h3><p>The study indicated the potential of green-synthesized CNP for eliminating the protoscoleces and in managing hydatid cysts through leveraging its antioxidant and anti-inflammatory characteristics. Nevertheless, additional investigations are necessary to elucidate the precise mechanisms of action and evaluate its effectiveness in clinical trials.</p><h3>Clinical Trial Number</h3><p>Not applicable.</p></div>","PeriodicalId":6932,"journal":{"name":"Acta Parasitologica","volume":"70 2","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
