title: Development of Trypanosoma cruzi in the vector in the absence of blood.
abstract: First stage nymphs of Triatoma infestans and Dipetalogaster maximus which had never fed after egg hatching, were allowed to ingest by artificial feeding a blood-free suspension of Trypanosoma cruzi trypomastigotes collected from experimentally infected mice. A high percentage of the vectors acquired a normal infection and produced infective stages. The parasite's development in the vector did not require blood but may have needed the presence of unknown factors secreted and/or excreted in the insect's digestive tract.
