A new protein (TiAP) from anterior midgut of Triatoma infestans is modulated by Trypanosoma cruzi.
TiAP doesn't interfere in the viability of T. cruzi trypomastigotes.
TiAP is able to control bacterial load inside anterior midgut of T. infestans.
TiAP is important in maintenance of T. cruzi – microbiota balance in the vector.
