Abstract

Freeze-thaw DNA extraction methods and PCR primers were compared to optimize detection of Cryptosporidium parvum and Toxoplasma gondii oocysts in different matrices. Increasing FT cycles did not increase parasite DNA detection, and primers targeting the 18S ssrRNA gene yielded the most sensitive detection of C. parvum oocysts.
