Triatoma infestans is more efficient than Panstrongylus megistus in obtaining blood meals on non Anaesthetized mice [PDF]

Memorias do Instituto Oswaldo Cruz, 1995
We compared the influence of the bug density in the capacity of Triatoma infestans and Panstrongylus megistus in obtaining blood meal in non anaesthetized mice. The regression anlysis for increase in body weight (mg) versus density (no.

Experimentally Induced Heat-Shock Tolerance inPanstrongylus megistus(Hemiptera: Reduviidae)

Journal of Medical Entomology, 2001
The survival and molting incidence of fifth-instar nymphs of Panstrongylus megistus (Burmeister, 1835), a vector of Chagas' disease, were investigated following sequential heat shocks in which a mild shock (35 or 40 degrees C, 1 h) preceded a more drastic one (40 degrees C, 12 h). The shocks were separated by 8-, 18-, 24-, or 72-h periods at 28 degrees

Oral transmission of Chagas disease from a One Health approach: A systematic review

Tropical Medicine &International Health, Volume 28, Issue 9, Page 689-698, September 2023., 2023
Abstract Objective To analyse acute Chagas disease (CD) outbreaks through a qualitative systematic review and discuss the determinants for its prevention and control. Methods Review of studies in which clinical cases of oral transmission were confirmed by parasitological and/or serological tests that included an epidemiological investigation of sources

Isolation and molecular characterization of a major hemolymph serpin from the triatomine, Panstrongylus megistus. [PDF]

Parasit Vectors, 2014
Chagas disease kills 2.5 thousand people per year of 15 million persons infected in Latin America. The disease is caused by the protozoan, Trypanosome cruzi, and vectored by triatomine insects, including Panstrongylus megistus, an important vector in Brazil.

Retrospective evaluation of the epidemiological importance of Triatoma infestans and Panstrongylus megistus in the transmission of Trypansoma cruzi in a region of southeastern Brazil. [PDF]

Rev Inst Med Trop Sao Paulo
Panstrongylus megistus is the most important autochthonous vector of Trypanosom cruzi, the etiological agent of Chagas disease, in the midwest region of the Minas Gerais State, Brazil. This study investigates the vectorial roles of Triatoma infestans and

Phylogenetic structure of geographical co‐occurrence among New World Triatominae species, vectors of Chagas disease

Journal of Biogeography, Volume 47, Issue 6, Page 1218-1231, June 2020., 2020
Abstract Aim The tropical niche conservatism (TNC) hypothesis is one of the most prominent evolutionary hypotheses that has been supported as an explanation for the diversity gradients of several animal taxa, mainly vertebrates. However, the validity of TNC for less‐known taxa such as disease vectors is not clear.

Trypanosomatid infections in captive wild mammals and potential vectors at the Brasilia Zoo, Federal District, Brazil

Veterinary Medicine and Science, Volume 6, Issue 2, Page 248-256, May 2020., 2020
Conservation projects in zoos require translocations of captive animals, which may spread pathogens. We aimed to verify the occurrence of vectors (triatomines and sandflies) and to investigate Trypanosoma cruzi and Leishmania infections in captive wild mammals in the Zoo Brasília.

Occurrence of positivity for Trypanosoma cruzi in triatomine from municipalities in Southeastern Brazil, from 2002 to 2004 Ocorrência e positividade para Trypanosoma cruzi em triatomíneos de municípios da região sudeste do Brasil, de 2002 a 2004

Revista da Sociedade Brasileira de Medicina Tropical, 2010
INTRODUCTION: from an epidemiological point of view, more than 120 species of triatomine (Hemiptera, Reduviidae) are known. The occurrence and positivity for Trypanosoma cruzi in triatomines in 16 municipalities of the Triângulo Mineiro and Alto ...
