Long PCR amplification of the entire mitochondrial genome from individual helminths for direct sequencing
Min Hu1, Aaron R Jex1, Bronwyn E Campbell1 & Robin B Gasser1
Abstract
Exploring mitochondrial (mt) genomes has significant implications for various fundamental research areas, including mt biochemistry and physiology, and, importantly, such genomes provide a rich source of markers for population genetics and systematic studies. Although some progress has been made, there is a paucity of information on mt genomes for many metazoan organisms, particularly invertebrates such as parasitic helminths, which relates mainly to the technical limitations associated with sequencing from tiny amounts of material. In this article, we describe a practical long PCR approach for the amplification and subsequent sequencing of the entire mt genome from individual helminths, which overcomes these limitations. The protocol includes the isolation of genomic DNA, long PCR amplification, electrophoresis and sequencing, and takes 
1–3 weeks to carry out. The present user-friendly, cost-effective approach has demonstrated utility to the study of a range of parasites, and has the potential to be applied to a wide range of organisms.
