Chemical composition and biological effects of essential oils from Artemisia absinthium L. cultivated under different environmental conditions
Oils from cultivated A. absinthium showed antiparasitic effects against Leishmania infantum and Trypanosoma cruzi with better results than the commercial samples. Expand
Tentative identification of the species of Balantidium from ostriches (Struthio camelus) as Balantidium coli-like by analysis of polymorphic DNA.
The morphological characteristics and genetic results suggest that the species name B. struthionis is a synonym of B. coli; however, until experimental infections are carried out to determine if the parasite is transmissible between pigs and ostriches, it would be preferable to tentatively designate it as B. E. coli-like. Expand
Selective Action of Acetogenin Mitochondrial Complex I Inhibitors
The in vivo effects of these compounds on S. littoralis and their cytotoxic effects on Sf9 and tumor cells were more predictable than their effect on T. cruzi and mammalian cells. Expand
In vitro screening of american plant extracts on Trypanosoma cruzi and trichomonas vaginalis.
To determine the antiprotozoal activity of 79 extracts from different plant families, including Asteraceae, Araceae, Moraceae, Solanaceae, Rhamnaceae, Zingiberaceae, Leguminosae and Sapotaceae, selected parts were separated, dried carefully and reduced to powder. Expand
Genetic heterogeneity in internal transcribed spacer genes of Balantidium coli (Litostomatea, Ciliophora).
The results show that the ITS2 secondary structure of the species considered follows the general pattern of other ciliates, although with some deviations, and do not support B. suis and B. struthionis as distinct species. Expand
Indole alkaloids from Geissospermum reticulatum.
Indole alkaloids isolated from Geissospermum reticulatum exhibited selective action and were more active against Leishmania than against Trypanosoma, and alkaloid 4 was also very active against L. infantum. Expand
Major components of Spanish cultivated Artemisia absinthium populations: Antifeedant, antiparasitic, and antioxidant effects
The insect antifeedant properties of plant extracts from different years and crops were tested against Spodoptera littoralis, Myzus persicae and Rhopalosiphum padi and their antioxidant, phytotoxic and antiparasitic effects were studied. Expand
Biological characterization of Trypanosoma cruzi strains.
Differences in transformation to metacyclic, in the percentage of infected cells as well as in the number of amastigotes per cell were observed among the strains, demonstrating the heterogeneity of natural populations of T. cruzi. Expand
Antileishmanial, antitrypanosomal, and cytotoxic screening of ethnopharmacologically selected Peruvian plants
Extracts (34) from eight plant species of the Peruvian Amazonia currently used in traditional Peruvian medicine, mostly as antileishmanial remedies and also as painkiller, antiseptic, antipyretic,Expand
Trypanocidal, trichomonacidal and cytotoxic components of cultivated Artemisia absinthium Linnaeus (Asteraceae) essential oil
The chemical composition of the fractions and the antiparasitic effects of fractions and their main compounds suggest that the activity of the VP is related with the presence oftrans-caryophyllene and dihydrochamazulene (main components of fractions VLC1 and VLC2 respectively). Expand
