TLDR
The high frequency of reactions suggests either cutaneous reactivity to T.infestans without prior sensitization or cross reactivity between P. megistus and T. infestans.Abstract:
We determined the frequency of cutaneous allergic reactions to bites of Triatoma infestans during xenodiagnosis in a rural community where Panstrongylus megistrus is the only domestic vector of Trypanosoma cruzi. Localized urticaria or more intense cutaneous allergic reactions at 48 and 72 hours were observed in 86.7% and 82.1% respectively of the individuals in our study. Urticaria was more severe in children and older adults and in women than in men. The high frequency of reactions suggests either cutaneous reactivity to T. infestans without prior sensitization or cross reactivity between P. megistus and T. infestans. A single application of topical corticosteroid or antihistamine medication did not reduce the cutaneous reactions.read more

TL;DR: Physicians in the United States should familiarize themselves with "kissing bugs" endemic to their area of practice and appreciate the medical implications of their bites as well as the potential for Chagas disease transmission.

Anticoagulant activity of Triatoma infestans and Panstrongylus megistus saliva (Hemiptera/Triatominae).
TL;DR: There are differences in anticoagulant activity and protein composition of triatomine saliva, and it is shown that T. infestans saliva interferes particularly with activity of factor VIII and factor V, but also affects other factors.

TL;DR: IgG1 reactive against TSGP is the main antibody present in individuals living in the triatomine-infested study areas, and also, IgG4 is found in the sera of insect-transmitted Chagas disease patients living in study areas.
