Mj. Walker et al., METHOD DETECTION LIMITS OF PCR AND IMMUNOFLUORESCENCE ASSAY FOR CRYPTOSPORIDIUM-PARVUM IN SOIL, Applied and environmental microbiology, 64(6), 1998, pp. 2281-2283
We determined and compared the method detection limits (MDLalpha) of a
PCR and an immunofluorescence assay (IFA) for detection of Cryptospor
idium parvum oocysts in soils. Based on the MDLalpha and the quantitat
ive nature and stability of the IFA, PCR analysis is not a useful scre
ening step for soil studies of oocyst transport.
