Toxoplasmosis is an important zoonosis worldwide. Here we determined the presence of Toxoplasma gondii antibodies in sera and T. gondii DNA in faeces of 215 domestic cats from veterinary clinics in the Lisbon area; 44 (20.5%) had anti-T. gondii IgG antibodies by the modified agglutination test (cut-off 1:40) and DNA was detected in 16 (35.6%) of 45 cat(More)
The proteasome proteolytic system is the major ATP-dependent protease in eukaryotic cells responsible for intracellular protein turnover. Schistosoma mansoni has been reported to contain an ubiquitin–proteasome proteolytic pathway, and many studies have suggested a biological role of proteasomes in the development of this parasite. Additionally, evidence(More)
The chemical composition and the in vitro schistosomicidal effects of the essential oil of Plectranthus neochilus (PN-EO) grown in Southeast Brazil was studied. β-Caryophyllene (1; 28.23%), α-thujene (2; 12.22%), α-pinene (3; 12.63%), β-pinene (4; 6.19%), germacrene D (5; 5.36%), and caryophyllene oxide (6; 5.37%) were the major essential oil constituents.(More)
Previously known from only two specimens collected in Uruguay, Prescottia ostenii Pabst is reported for the first time from Rio Grande do Sul, Southern Brazil. Several morphological features lacking in the original description are described and illustrated. The taxonomic affinities of this species are discussed, based on vegetative and floral morphology.
Foeniculum vulgare Mill. (Apiaceae), known as fennel, is a widespread aromatic herbaceous plant, and its essential oil is used as additive in the food, pharmaceutical, cosmetic, and perfume industries. The in vitro antischistosomal activity and cytotoxic effects against V79 cells of the essential oil of F. vulgare cultivated in southeastern Brazil (FV-EO)(More)
