A total of 245 fresh fecal samples were collected from 87 dogs, 63 cats, and 95 cattle in Shiraz, the capital city of Fars province, between July 2021 and August 2022. None of the animals showed gastrointestinal signs such as diarrhea, and all fecal samples had normal consistency. Upon parasite observation using light microscopy, a DNA fragment of <i>G. duodenalis tpi</i> gene was amplified using nested-PCR. Using direct wet mount and Wheatley's trichrome staining examination, 9 out of 245 samples (3.7%; 1 from dogs and 8 from cattle) tested positive for <i>G. duodenalis</i>. Molecular methods confirmed 1.1% (1/87) of dogs and 8.4% (8/95) of cattle to be positive. Giardiasis was not detected in cats.

In the present in vitro study, the effect of Met on the viability and ultrastructure of <i>Schistosoma mansoni</i> adults and juveniles in comparison with the standard anti-schistosomal drug, praziquantel (PZQ), was investigated. Adults and juveniles were treated in vitro with 5 µM PZQ and/or 10 mM Met. The viability of the treated worms was screened over a three-day period by light microscopy and recorded as mortality rates (MR). The alterations in the ultrastructure were verified using scanning and transmission electron microscopy. Met showed significant anti-schistosomal activity against both adults and juveniles and resulted in severe tegumental damage in the form of loss of integrity and architecture, with evident vacuolation suggestive of increased autophagy. Met might be a potential drug either alone or as an adjuvant to PZQ for the treatment of schistosomiasis <i>mansoni</i> and warrant its further assessment in animal models of disease.</p>","PeriodicalId":16664,"journal":{"name":"Journal of Parasitic Diseases","volume":"49 1","pages":"69-83"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11832992/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143458492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
