A 220-kDa surface protein (L220) with lectin activity from Entamoeba histolytica trophozoites has been characterized previously (J. L. Rosales-Encina, I. Meza, A. López-de-León, P. Talamás-Rohana, and M. Rojkind, J. Infect. Dis. 156:790-797, 1987). This molecule is involved in the adhesion process (I. Meza, F. Cázares, J. L. Rosales-Encina, P.(More)
BACKGROUND For many years Chiapas, Mexico's poorest state, has had the highest rate of child mortality due to intestinal infections of unknown etiology in the country. To begin identifying the infectious agents, our work determined the prevalence of intestinal parasites as well as malnutrition in children from Chiapas's three most impoverished(More)
It is generally accepted that hydrolytic and cytolytic amebic components are involved in the pathogenic mechanisms of E. histolytica. We have now identified a lytic activity in two membrane proteins of 23.5 kDa and 25 kDa, which are able to lyse rat erythrocytes. The activity was purified from total homogenates of the virulent strains HM1:IMSS and(More)
Acetogenins from Annonaceae (ACG) are potent inhibitors of the mitochondrial complex I, they present cytotoxic activity on neoplasic lines, including those with multiresistance to drugs. In vivo antitumor activities of some ACG have been reported; however, no information is available regarding the relationship between their cytotoxic activity in cell(More)
