Comparison of different methods for cyst DNA extraction. Replicate samples of approximately 800 cysts were extracted using the DNEasy Tissue Kit or QIAmp Stool DNA kit, with or without mechanical breakage (bead-beating). Extraction efficiency was assessed based on (A) the total amount of DNA recovered and (B) the extent of amplification by real-time PCR (as a proxy for the number of ribosomal RNA gene copies recovered).
