Anti-triatomine saliva immunoassays for the evaluation of impregnated netting trials against Chagas disease transmission

► We examined the effect of impregnated nets on exposure of guinea pigs to triatomine. ► We analysed antibody responses of guinea pigs to vector saliva. ► Five control animals showed strong immune reactions to T. infestans saliva. ► No animals under insecticide-impregnated nets reacted strongly to T. infestans saliva.
