原始语种摘要: Abstract(#br)Trypanosoma rangeli ( T. rangeli ), a parasite, is not pathogenic to human but pathogenic to some vector species to induce the behavior changes of infected vectors and subsequently impact the transmission dynamics of other diseases such as Chagas disease which shares the same vector species. Here we develop a mathematical model and conduct qualitative analysis for the transmission dynamics of T. rangeli . We incorporate both systemic and co-feeding transmission routes, and account for the pathogenic effect using infection-induced fecundity and fertility change of the triatomine bugs. We derive two thresholds R v (the triatomine bug basic reproduction number) and R 0 (the T. rangeli basic reproduction number) to delineate the dynamical behaviors of the ecological and...
