Chagas disease is a significant public health risk in rural and semi-rural areas of Venezuela. Triatomine infection by the aetiological agent Trypanosoma cruzi is also observed in the Metropolitan District of Caracas (MDC), where foodborne T. cruzi o

Analysis of genetic polymorphism is a powerful tool for epidemiological surveillance and research. Powerful inference from pathogen genetic variation, however, is often restrained by limited access to representative target DNA, especially in the stud

Triatomines are the vectors of Trypanosoma cruzi, the etiological agent of Chagas disease. Although Triatoma and Rhodnius are the most-studied vector genera, other triatomines, such as Panstrongylus, also transmit T. cruzi, creating new epidemiologic

Panstrongylus geniculatus and four other species of triatomine bug involved in the Trypanosoma cruzi enzootic cycle: high risk factors for Chagas’ disease transmission in the Metropolitan District of Caracas, Venezuela

Autor: Hernán J Carrasco, Maikell Segovia, Juan C Londoño, Jaire Ortegoza, Marlenes Rodríguez, Clara E Martínez

Publikováno v: Parasites & Vectors, Vol 7, Iss 1, Pp 1-15 (2014)

Abstract Background Chagas' disease is caused by the protozoan Trypanosoma cruzi and is autochthonous to the Americas. Its distribution depends on triatomine bugs that are responsible for the transmission of the disease. In 2005, we reported the pres

Molecular Epidemiologic Source Tracking of Orally Transmitted Chagas Disease, Venezuela

Autor: Maikell Segovia, Hernán J. Carrasco, Clara E. Martínez, Louisa A. Messenger, Anaibeth Nessi, Juan C. Londoño, Raul Espinosa, Cinda Martínez, Mijares Alfredo, Rafael Bonfante-Cabarcas, Michael D. Lewis, Belkisyolé A. de Noya, Michael A. Miles, Martin S. Llewellyn

Publikováno v: Emerging Infectious Diseases, Vol 19, Iss 7, Pp 1098-1101 (2013)

Oral outbreaks of Chagas disease are increasingly reported in Latin America. The transitory presence of Trypanosoma cruzi parasites within contaminated foods, and the rapid consumption of those foods, precludes precise identification of outbreak orig

Chagas disease is an endemic zoonosis native to the Americas and is caused by the kinetoplastid protozoan parasite Trypanosoma cruzi. The parasite is also highly genetically diverse, with six discrete typing units (DTUs) reported TcI - TcVI. These DT

Trypanosoma cruzi IIc: phylogenetic and phylogeographic insights from sequence and microsatellite analysis and potential impact on emergent Chagas disease.

Publikováno v: PLoS Neglected Tropical Diseases, Vol 3, Iss 9, p e510 (2009)

Trypanosoma cruzi, the etiological agent of Chagas disease, is highly genetically diverse. Numerous lines of evidence point to the existence of six stable genetic lineages or DTUs: TcI, TcIIa, TcIIb, TcIIc, TcIId, and TcIIe. Molecular dating suggests
