Abstract: A PCR Differentiation Method, a hybrid of the US EPA and MOE methods, for quantifying human infectious C. parvum/C. hominis as a group and non-human infectious C. andersoni/C. muris was developed. Primers and probe sets targeting the hsp70 gene were designed for C. andersoni/C. muris; those for C. parvum/C. hominis were obtained from the MOE method. Results showed that C, andersoni/C. muris primers were specific for C. andersoni/C. muris oocysts, while those for C. parvum/hominis primers detected C. parvum/hominis and C. meleagridis. All primers were then used to quantify oocysts from urban and agricultural environmental water samples in Kitchener/Waterloo. Human infectious Giardia lamblia was also incorporated into this study. C. parvum/C. hominis and Giardia lamblia were detected at urban and agricultural areas, whereas C. andersoni/C. muris was only detected at agricultural sites. The PCR Differentiation Method is a reliable method for quantifying Cryptosporidium and Giardia lamblia in environmental water samples.
