Can sexual transmission support the enzootic cycle of Trypanosoma cruzi?
BACKGROUND Trypanosoma cruzi circulates in sylvatic habitats, mainly through blood-feeding triatomines, although other routes also contribute to its dispersion. Sexual transmission of T. cruzi is an understudied topic, especially among wild mammals. Because of the difficulties inherent to field work, experimentally infected mice are frequently used to evaluate the transmission of T. cruzi. OB...
متن کاملEnzootic transmission of Trypanosoma cruzi and T. rangeli in the Federal District of Brazil.
The Federal District of Brazil (DF) lies within the Cerrado biome, where open shrubland (savannas) is interspersed with riverside gallery forests and permanent swamps (veredas). Trypanosoma cruzi-infected native triatomines occur in the area, but the enzootic transmission of trypanosomatids remains poorly characterized. A parasitological survey involving sylvatic triatomines (166 Rhodnius negle...
متن کاملThe Life Cycle of Trypanosoma Cruzi
Since the discovery of Trypanosoma cruzi as the parasite that causes Chagas disease, nearly a century ago, the details of the organism's life cycle have fascinated scientists. T. cruzi is a single-celled eukaryote with a complex life cycle alternating between reduviid bug vectors and vertebrate hosts. It is able to adapt via the process of cellular differentiation to replicate within the divers...
متن کاملThe life cycle of Trypanosoma cruzi revisited.
The basic features of the life cycle of Trypanosoma cruzi have been known for nearly a century. Various aspects of the life cycle, however, have been elucidated only recently, whilst others remain either controversial or unstudied. Here, we present a revised life cycle influenced by recent findings and specific questions that remain unresolved.
متن کاملAutochthonous Transmission of Trypanosoma cruzi, Louisiana
Autochthonous transmission of the Chagas disease parasite, Trypanosoma cruzi, was detected in a patient in rural New Orleans, Louisiana. The patient had positive test results from 2 serologic tests and hemoculture. Fifty-six percent of 18 Triatoma sanguisuga collected from the house of the patient were positive for T. cruzi by PCR.
