Abstract:
We determined and compared the method detection limits (MDLalpha) of a PCR and an immunofluorescence assay (IFA) for detection of Cryptosporidium parvum oocysts in soils. Based on the MDLalpha and the quantitative nature and stability of the IFA, PCR analysis is not a useful screening step for soil studies of oocyst transport.
