Feces from wild Triatoma dimidiata induces local inflammation and specific immune response in a murine model.

In endemic regions for Triatoma dimidiata the vector for Chagas disease, subjects can be in contact with insect`s feces several times through a lifetime. The triatomine’s digestive tract is colonized by diverse but few dominant genera of microorganisms. The immune responses to microbiota feces are poorly known in mammal hosts.

Comparative 2-D electrophoresis of salivary proteins in Triatoma dimidiata and Rhodnius prolixus (Hemiptera: Reduviidae) and major cross-reactive antigens.

An immune response to triatomine’s saliva is an immunological marker of exposure to triatomine bites. However, considerable variability in salivary protein profiles did exist among species. In the present work, we compare salivary proteins from Mexican Triatoma dimidiata and Rhodnius prolixus using 2-D electrophoresis.
