 en Trypanosoma rangeli check for this species in other resources interactions within the vector Rhodnius prolixus check for this species in other resources - A mini review
Patrícia Azambuja & Eloi S Garcia

Abstract

This article is an integrative mini review of the research on the interactions between Trypanosoma rangeli check for this species in other resources and the insect vector, Rhodnius prolixus check for this species in other resources . Special attention is given to the interactions of these parasites with the gut environment, gut walls, with hemolymph invasion, hemocytes, hemocyte microaggregations, prophenoloxidase-activating system, superoxide, and nitric acid generation and eicosanoid pathways. We described factors affecting vectorial capacity and suggested that T. rangeli may modulate the hemocoelic invasion and the survival of the parasites by overcoming the cellular and humoral defense reactions of the insect vector at different physiological events. The mechanisms of these interactions and their significance for parasite transmission are discussed.
