Garcia Multidisciplinaria (Ciencias Naturales y Exactas) vector parasites Trypanosomes Rhodnius prolixus ABSTRACTThis review outlines aspects on the developmental stages of Trypanosoma cruzi and Trypanosoma rangeli inthe invertebrate host, Rhodnius prolixus. Special attention is given to the interactions of these parasites withgut and hemolymph molecules and the effects of the organization of midgut epithelial cells on the parasitedevelopment. The vector insects permissiveness to T. cruzi, which develops in the vector gut, largely dependson the host nutritional state, the parasite strain and the molecular interactions with trypanolytic compounds,lectins and resident bacteria in the gut. T. rangeli invades the hemocoel and once in the hemolymph, can berecognized and activates the defense system of its insect vector, i.e., the prophenoloxidase system, phagocytosis,hemocyte microaggregation, superoxide and nitric oxide activity and the eicosanoid biosynthesispathway. Taken together, these findings not only provide a better understanding of the interactions parasite- insect vector, but also offer new insights into basic physiological processes involved in the parasitestransmission. 2005 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32777304 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.3 Vol.77 |
