SpletCryptosporidium sp. was detected in stool and biopsy samples of two HIV-infected patients. DNA was extracted from feces, biopsy specimens, blood, and cerebrospinal fluid (CSF). All samples were analyzed by nested PCR-RFLP of the 18S rDNA, real-time PCR, and gp60 subtyping. Cryptosporidium DNA was detected in stool and tissue samples and it was ... SpletThe observation revealed that combination of nested-PCR and ELISA leads to a sensitive and specific identification of three copies in HIV-infected; the specificity and sensitivity were 95% and 96.7%, respectively. In conclusion, PCR-ELISA was 10 fold more sensitive than nested-PCR.
