Detection of viable Cryptosporidium parvum oocysts by PCR.
PCR was used to detect and specifically identify a gene fragment from Cryptosporidium parvum. An 873-bp region of a 2,359-bp DNA fragment encoding a repetitive oocyst protein of C. parvum was shown to be specifically amplified in C. parvum. An excystation protocol before DNA extraction allowed the differentiation between live and dead Cryptosporidium parvum oocysts.
