Although the current treatments for toxoplasmosis may be associated with adverse effects and limited efficacy for different biological forms of the parasite, evidence suggests that alkaloid molecules such as harmaline and piperine exhibit antiparasitic effects against protozoa parasites. This investigation aimed to evaluate the in vitro effect of harmaline and piperine against T. gondii tachyzoites in infected Vero cell cultures. After 24 hours of host cell infection, the cultures were treated with harmaline or piperine (0.49 to 15.63 µg/mL). Negative and positive controls were RPMI/DMSO (0.1%) and sulfadiazine (200 µg/mL). Harmaline significantly reduced parasite multiplication by 20% compared to the negative control, while piperine decreased between 55.56% and 88.89% in a dose-dependent manner. According to an intracellular parasite proportion scale, it was observed that the Vero cells with low or moderate parasitic proliferation were more prevalent after the alkaloid treatment. The study demonstrated that the alkaloids had antiparasitic effects on T. gondii, with piperine being the most effective. Additional studies must be carried out to clarify other aspects of the action of the alkaloids on parasites.","PeriodicalId":48990,"journal":{"name":"Revista Brasileira De Parasitologia Veterinaria","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11452066/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142299210","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}

The EOs were obtained by hydrodistillation using a modified Clevenger apparatus for 2 h. Qualitative and quantitative analysis were performed via gas chromatography. The findings revealed that dillapiole was the predominant substance in both EOs, accounting for 77.6% (rainy) and 85.5% (dry) of the EOs. These EOs exhibited high efficacy against the parasite C. felis felis, resulting in 100% egg mortality at a concentration of 100 μg/mL and 100% mortality for adult fleas starting from 1,000 μg/mL. Dillapiole standard was also effective but at a relatively high concentration. This finding suggested that EOs from P. aduncum exhibit cytotoxicity against these pests and might hold potential for commercial production, offering practical applications for such bioprospecting.

Infected wild boar were found near peri-urban areas, demonstrating the importance of routine epidemiological surveillance and sanitary measures in and around cities.

The infestation was identified by the presence of whitish plaques on the integument of five animals, and the diagnosis was confirmed through skin scrapings. BiokosTM is a lipopeptide derived from the bacteria Pseudomonas that can destroy the functionality of the cell membrane of ciliated protozoa. The action of BiokosTM does not harm animals and the environment because the compound degrades into amino acids and fatty acids within days. A 0.15 m3 (150 L) aquarium was treated with an Ich-AwayTM water conditioner manufactured by the Danish company Sundew ApS, which has BiokosTM as the active ingredient. Six tablets were added to the water daily for two days, and new skin scrapings were performed. The fish were clinically well and no longer possessed lesions or parasites.

Therefore, baths with albendazole at 500 mg/L, as used in this strategy, can be recommended for controlling and treating infections by monogeneans in C. macropomum.","PeriodicalId":48990,"journal":{"name":"Revista Brasileira De Parasitologia Veterinaria","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11452061/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142082331","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}
