Abstract |
Acquiring genomic material from avian malaria parasites for genome sequencing has proven problematic due to the nucleation of avian erythrocytes, which produces a large ratio of host to parasite DNA (∼1 million to 1 bp). We tested the ability of laser capture microdissection microscopy to isolate parasite cells from individual avian erythrocytes for four avian Plasmodium species, and subsequently applied whole genome amplification and Illumina sequencing methods to Plasmodium relictum (lineage pSGS1) to produce sequence reads of the P. relictum genome. We assembled ∼335 kbp of parasite DNA from this species, but were unable to completely avoid contamination by host DNA and other sources. However, it is clear that laser capture microdissection holds promise for the isolation of genomic material from haemosporidian parasites in intracellular life stages. In particular, laser capture microdissection may prove useful for isolating individual parasite species from co-infected hosts. Although not explicitly tested in this study, laser capture microdissection may also have important applications for isolation of rare parasite lineages and museum specimens for which no fresh material exists. |
