Mammalian serum or bovine serum albumin are essential for Trichomonas vaginalis cultivated under axenic conditions. Unfortunately, these components inhibit several biological properties of these parasites. PACSR is a serum replacement, free of bovine serum albumin. used for axenic cultivation of Entamoeba histolytica. We show that PACSR is also useful for(More)
The cyst of Entamoeba histolytica is responsible for amebiasis infection. However, no axenic in vitro system exists that promotes mass encystation for studying this process of this human-infecting parasite. Cyst-like structures of E. histolytica obtained in this work were induced using TYI-S-33 media in combination with enterobacterias Escherichia coli and(More)
Knowledge of Entamoeba histolytica biology in the last 17 years has been acquired largely as a consequence of this parasite's axenic cultivation in TPS-1 or TYI-S-33 media. Unfortunately, there are often low yields in these media, due to variability of their main components, Panmede and yeast extract. We describe a medium, PEHPS, of which the main(More)
BACKGROUND Tuberculosis is a chronic disease caused mainly by Mycobacterium tuberculosis. The emergence of antibiotic-resistant strains of this species underscores the need for novel effective drugs against resistant mycobacteria as first-line antituberculosis medications. METHODS Crude aqueous (obtained by decoction, in accordance with the traditional(More)
Trichomonad total extracts (TTE), or vesicular (P30) and soluble (530) subcellular fractions from 3 pathogenic Trichomonas vaginalis strains (GT-3. GT-13. and GT-15), lysed both human and Sprague-Dawley rat erythrocytes in a time- and dose-dependent manner. The entire hemolytic activity of TTE was located in P30, showing 2 peaks of maximum activity, one at(More)
Background: There is a number of alternative and complementary therapeutics that are unproven or have not been properly tested. For past twenty years, the transfer of bio-energetic information has been recognized as a novel scientific approach capable of contributing to improved therapy in the management of several diseases through the so-called(More)
