Estimating contact process saturation in sylvatic transmission of Trypanosoma cruzi in the United States
(Public Library of Science, 2010-04)
Although it has been known for nearly a century that strains of Trypanosoma cruzi, the etiological agent for Chagas' disease, are enzootic in the southern U.S., much remains unknown about the dynamics of its transmission ...
The role of the ratio of vector and host densities in the evolution of transmission modes in vector-borne diseases. The example of sylvatic Trypanosoma cruzi
Pathogens may use different routes of transmission to maximize their spread among host populations. Theoretical and empirical work conducted on directly-transmitted diseases suggest that horizontal (i.e., through host ...
The role of adaptations in two-strain competition for sylvatic Trypanosoma cruzi transmission
(Taylor and Francis Online, 2012-08)
This study presents a continuous-time model for the sylvatic transmission dynamics of two strains of Trypanosoma cruzi enzootic in North America, in order to study the role that adaptations of each strain to distinct modes ...
Graphical analysis of evolutionary trade-off in sylvatic Trypanosoma cruzi transmission modes
The notion of evolutionary trade-off (one attribute increasing at the expense of another) is central to the evolution of traits, well-studied especially in life-history theory, where a framework first developed by Levins ...
