Habitat	Total samples	No. (%) T. cruzi positive*	Total no. identified lineages†		Total
			Cordillera	Paraguari
Domicile	191	67 (35)	7	23	30

^*T. cruzi-positive samples identified by using species-specific primers TCZ 1–TCZ 2 and 121–122.

^†Lineage-positive samples identified by using lineage-specific primers for mini-exon and 24Sα ribosomal RNA genes.
