What additional tests could be performed for confirmation?

Difficult one! I think it might be Cryptosporidium pavum owing to the site and morphology of the parasite, the symptoms and the fact the patient is HIV positive; crypto can be fatal in HIV+ and is one of the most common infections assoc. with HIV.
Other tests include Z-N staining...is there an antigen test for this????
Cryptosporidium -- used a modified acid-fast stain to confirm.
Cryptosporidium oocysts. Should be about 5 microns in diameter. If an AIDS patient, look also for Isospora belli.
Cryptosporidia. We've seen lot's in SF and oddly almost never recognized isospora on biopsy which is intraepithelial usually (only see maybe 1/yr in stool so I don't think just stupid pathologist).
Agree: Cryptosporidium
Cryptosporidium, and I believe there is an antigen test, and also PCR for this, though not widely done.
Agree - Cryptosproidium pavum
stool sample examination?
