title: DNA from this sample was extracted from a Cyst biopsy (L. byrdi infection). It contains a mixture of Host and Parasite DNA
design: O. grillus targeted for DNA extraction were preserved at -80C and dissected in chilled PBS. Amphipods were classified infected if they were orange and carried at least one cyst, or uninfected if they were brown and carried no cysts. DNA was extracted using a Qiagen RNeasy Mini Kit and diluted to equimolar concentrations prior to sequencing.
