This also applies to the interactions and scratches in different locales. The aim of this study was to describe D. renale occurrence in 12 animals at an interface of the domestic-wild cycle and to detail two specific cases of these, one domestic and one wild canine (Chrysocyon brachyurus) from the same microregion of the Brazilian Cerrado. The difficulty in diagnosing dioctophimosis is related to nonspecific clinical signs. Over the last five years, 12 cases of D. renale have been reported in domestic and wild canids, two of which are described in full in this study. The expansion of livestock farming and urbanization of biomes, fragmentation of floral areas, and destruction of natural areas have increased the proximity between domestic and wild animals, and consequently, the occurrence of infectious and parasitic diseases. Its probability of occurrence in humans represents a public health risk.","PeriodicalId":48990,"journal":{"name":"Revista Brasileira De Parasitologia Veterinaria","volume":"34 1","pages":"e012424"},"PeriodicalIF":1.3,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11961071/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143765560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the objective of this study was to develop and evaluate a laser prototype with a voltage of 5 V and power of 1000 mW to reduce the development of R. microplus. The methodology evaluated did not result in a high mortality rate; therefore, it was necessary to carry out a larval migration test. To carry out the test, 3 treatments were evaluated in triplicate (negative controls H20, 60% ethanol and positive control), with 20 larvae were evaluated for each replicate of the treatments, which resulted in an increase in the percentage of migration from 2.5% and 3.2% to above 94.9% and 93.5% in the negative controls, while in the positive control group there was no showed a significant change in migration, reaching close to 100%.

Ten specimens of Saimiri sciureus had their intestines analyzed and the parasites recovered were cleaned, quantified, fixed and observed using light microscopy and scanning electron microscopy, and fragments of the intestine were separated for histological analysis to identify the alterations. All the animals were parasitized, and a total of 50 specimens representing the Acanthocephala Phylum were recovered, which morphologically showed characteristics compatible with Prosthenorchis elegans (Diesing, 1851). Light microscopy revealed the presence of parasites attached to the mucosal layer, passing through the underlying layers until they reached the muscular layer. Scanning electron microscopy showed the tissue lesions caused by the proboscis hooks and the flattening of the intestinal villi in the presence of the parasite. The presence of the parasites in the intestine changed the morphology of the organ, possibly causing loss of functionality at the site of attachment and adjacent tissue.","PeriodicalId":48990,"journal":{"name":"Revista Brasileira De Parasitologia Veterinaria","volume":"34 1","pages":"e021824"},"PeriodicalIF":1.3,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11961073/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143765558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carvacrol was subjected to benzoylation and analyzed by gas chromatography coupled to mass spectrometry (GC/MS). The activity of BC and carvacrol was evaluated against H. contortus in the egg hatching test. The in silico study was based on molecular docking with the β-tubulin and thiabendazole used as control. The acute toxicity test was performed with BC and carvacrol by up-and-down procedure (limit test: 2,000 mg/kg) in Wistar rats. GC/MS confirmed the benzoylation. BC and carvacrol inhibited egg hatching by 99.70 and 98.89% at concentrations of 3.16 and 1 mg/mL, respectively, and interacted with β-tubulin. No mortality was caused by compounds, but rats treated with carvacrol demonstrated intoxication signs.

Twenty-three individuals were captured and classified as male, female, adult, or juvenile. The fecal samples were analyzed using various coprodiagnostic techniques. The eggs and oocysts were identified by microscopic evaluation of their morphology and morphometry. Twelve parasite species were identified: nine nematodes, one acanthocephalan, and two protozoans. In addition, an Adeleid coccidia considered pseudoparasite was found. The most prevalent parasite species (>50%) were Eimeria sp, Cruzia sp., Aspidodera sp., and Gnathostoma turgidum, and nematode larvae. No significant differences were observed between parasite prevalence and host sex or age. Parasites of public health interest, such as Trichuris spp., Capillariidae nematodes, Strongyloides spp., and Giardia spp., were also identified.
