Variation in Trypanosoma cruzi clonal composition detected in blood patients and xenodiagnosis triatomines: implications in the molecular epidemiology of Chile. [PDF]

American Journal of Tropical Medicine and Hygiene, 2006
To identify Trypanosoma cruzi clones from chronically infected individuals, they were transferred to triatomines by the xenodiagnosis test (XD) with Triatoma infestans.

Toll Receptors Type-2 and CR3 Expression of Canine Monocytes and Its Correlation with Immunohistochemistry and Xenodiagnosis in Visceral Leishmaniasis

PLoS ONE, 2011
The aim of the present study was to investigate TLR2 expression in peripheral blood monocytes from dogs naturally infected with Leishmania (Leishmania) infantum to determine whether it correlates with CD11b/CD18 (CR3) expression, and to evaluate the ...

Light effect on feeding of first instar Dipetalogaster maximus in xenodiagnosis [PDF]

Revista da Sociedade Brasileira de Medicina Tropical, 1993
over a period of ten years suggest that a smaller quantity of blood is being ingested by hungry first instar bugs1 3. Since in Mexico the majority of bugs are first instar of diumal habit it was suggested that feeding might be related to light intensity2.

Quantification by real-time PCR of Trypanosoma cruzi DNA in samples of Triatoma infestans used in xenodiagnosis of chronic Chagas disease patients

Parasites & Vectors, 2016
Trypanosoma cruzi multiplies and differentiates in the digestive tract of triatomine insects. Xenodiagnosis (XD) is a parasitological tool in which the insect vectors acts as a biological culture medium to amplify and detect T. cruzi infection in mammals.

Studies in search of a suitable experimental insect model for xenodiagnosis of hosts with Chagas' disease. 4--The reflection of parasite stock in the responsiveness of different vector species to chronic infection with different Trypanosoma cruzi stocks. [PDF]

Revista de Saúde Pública, 1990
Previous studies (1982, 1987) have emphasized the superiority of sylvatic vector species over domestic species as xenodiagnostic agents in testing hosts with acute or chronic infections by T. cruzi "Y" stock. The present study, which is unique in that it

Heterogeneities in leishmania infantum infection : using skin parasite burdens to identify highly infectious dogs [PDF]

, 2013
Background: The relationships between heterogeneities in host infection and infectiousness (transmission to arthropod vectors) can provide important insights for disease management.

Trypanosoma cruzi detection in blood by xenodiagnosis and polymerase chain reaction in the wild rodent Octodon degus.

The American Journal of Tropical Medicine and Hygiene, 2007
We detected Trypanosoma cruzi in blood samples of the wild rodent Octodon degus by xenodiagnosis and a polymerase chain reaction (PCR) using the domestic and wild vectors of Chagas disease, Triatoma infestans and Mepraia spinolai, respectively.
