Detection of Trypanosoma cruzi by Polymerase Chain Reaction

Methods Mol Biol. 2016:1392:125-41. doi: 10.1007/978-1-4939-3360-0_12.

Abstract

American Trypanosomiasis (Chagas disease) is an infectious disease caused by the hemoflagellate parasite Trypanosoma cruzi which is transmitted by reduviid bugs. T. cruzi infection occurs in a broad spectrum of reservoir animals throughout North, Central, and South America and usually evolves into an asymptomatic chronic clinical stage of the disease in which diagnosis is often challenging. This chapter describes the application of polymerase chain reaction (PCR) for the detection of Trypanosoma cruzi DNA including protocols for sample preparation, DNA extraction, and target amplification methods.
