Approximate amplicon sizes of gene targets and lineage determination in Trypanosoma cruzi

Strain Mini-exon, bp 24S α rRNA, bp 18S rRNA, bp Lineage

*Denotes isolates used as representative banding patterns seen for classic lineage typing.
†Because of atypical banding patterns, a clear definition of an isolate as type I vs. type IIa could not be obtained.
