identification of cryptosporidium species and genotypes in scottish raw and drinking waters during a one-year monitoring period.we analyzed 1,042 cryptosporidium oocyst-positive slides (456 from raw waters and 586 from drinking waters) of which 55.7% contained 1 or 2 oocysts, to determine species/genotypes present in scottish waters. two nested pcr-restriction fragment length polymorphism (rflp) assays targeting different loci (1 and 2) of the hypervariable region of the 18s rrna gene were used for species identification, and 62.4% of samples were amplified with at least one of the pcr assays. more samples (577 slides; 4 ...201020639357
