A metapopulation model for sylvatic T. cruzi transmission with vector migration
Mathematical Biosciences and Engineering, 2013 This study presents a metapopulation model for the sylvatic transmission of Trypanosoma cruzi, the etiological agent of Chagas' disease, across multiple geographical regions and multiple overlapping host-vector transmission cycles.Classical qualitative ...

TcI isolates of Trypanosoma cruzi exploit the antioxidant network for enhanced intracellular survival in macrophages and virulence in mice [PDF]
, 2016 Trypanosoma cruzi species is categorized into six discrete typing units (TcI to TcVI) of which TcI is most abundantly noted in the sylvatic transmission cycle and considered the major cause of human disease. In our study, the TcI strains Colombiana (COL),

Vox Sanguinis, EarlyView.Abstract Background and Objectives According to the World Health Organization, more than 1 billion people are at risk of leishmaniasis in over 89 countries. Environmental changes such as deforestation, urban expansion and climate change facilitate the spread of sand fly vectors and reservoirs, increasing disease transmission.

Repertoire, genealogy and genomic organization of cruzipain and homologous genes in Trypanosoma cruzi, T. cruzi-like and other trypanosome species. [PDF]
PLoS ONE, 2012 Trypanosoma cruzi, the agent of Chagas disease, is a complex of genetically diverse isolates highly phylogenetically related to T. cruzi-like species, Trypanosoma cruzi marinkellei and Trypanosoma dionisii, all sharing morphology of blood and culture ...

Zika virus surveillance post‐epidemic in blood donors from São Paulo, Brazil 2016–2020
Transfusion Medicine, Volume 36, Issue 1, Page 59-65, February 2026.Abstract Introduction Zika virus (ZIKV) is primarily transmitted through the bite of the Aedes aegypti mosquito, though transmission via blood transfusion has also been documented. During the 2015 ZIKV epidemic in Brazil, severe complications were observed in pregnant women, leading to fetal microcephaly. This study evaluated the persistence of ZIKV in

Evidence of meaningful levels of Trypanosoma cruzi in platelet concentrates from seropositive blood. [PDF]
, 2015 BACKGROUND: According to the reported cases of transfusion-acquired Trypanosoma cruzi infection, the risk of T. cruzi transfusion transmission appears to be higher with platelet (PLT) products than with other blood components.
